Crazy Cats and Brain Parasites


Brain parasitesIt reads like a script for a scary movie: an alien parasite invading our brains, taking control of our minds, changing our behaviour silently, secretly; making us do what it wants. And it’s happening now, in homes across Canada and the USA. Alien puppet masters over-running the nation, one household at a time.

But it’s not fiction, although my scenario is a trifle exaggerated.

They’re not some right-wing aliens from outer space subverting our natural goodness and compassion; not some cyber-bullying bloggers dripping political poison into the gullible minds of their readers.They are microscopic, found worldwide, on land and in water – including saltwater – and may be infecting people you know this very minute. Or even you. They’re Toxoplasma gondii; an amoebic parasite pretty much capable of infecting any warm-blooded creature.

Where they breed, however, is in your cat, and are then excreted in their feces:

Although T. gondii can infect, be transmitted by, and asexually reproduce within humans and virtually all other warm-blooded animals, the parasite can sexually reproduce only within the intestines of members of the cat family (felids). Felids are therefore defined as the definitive hosts of T. gondii, with all other hosts defined as intermediate hosts.

As an owner of four cats and having had cats most of my life, this is troubling. But not entirely new. Back in 2012, in an article in The Atlantic, titled, “How Your Cat Is Making You Crazy,” Kathleen MacAuliffe wrote:

The parasite, which is excreted by cats in their feces, is called Toxoplasma gondii (T. gondii or Toxo for short) and is the microbe that causes toxoplasmosis—the reason pregnant women are told to avoid cats’ litter boxes. Since the 1920s, doctors have recognized that a woman who becomes infected during pregnancy can transmit the disease to the fetus, in some cases resulting in severe brain damage or death. T. gondii is also a major threat to people with weakened immunity: in the early days of the AIDS epidemic, before good antiretroviral drugs were developed, it was to blame for the dementia that afflicted many patients at the disease’s end stage. Healthy children and adults, however, usually experience nothing worse than brief flu-like symptoms before quickly fighting off the protozoan, which thereafter lies dormant inside brain cells—or at least that’s the standard medical wisdom.

But if Flegr is right, the “latent” parasite may be quietly tweaking the connections between our neurons, changing our response to frightening situations, our trust in others, how outgoing we are, and even our preference for certain scents. And that’s not all. He also believes that the organism contributes to car crashes, suicides, and mental disorders such as schizophrenia. When you add up all the different ways it can harm us, says Flegr, “Toxoplasma might even kill as many people as malaria, or at least a million people a year.”

To be fair to cats, the parasites live in soil, too, so they’re hard to avoid. Plus they’re also found in undercooked meat. You like your steak blue? Or bloody rare? You may be inviting this parasite into your brain. And also if you drink contaminated water or eat uncooked or undercooked shellfish. Those raw oysters you love? Parasite havens. Yum.

Timothy Leary Was Right. Maybe.


This is your brain on drugs
This is your brain on drugs. Or rather, the right-hand image is your brain on psilocybin. The other side is your brain on a non-psychedelic drug. Researchers recently discovered some amazing facts about how our brains work on some chemicals. And some psychedelic drugs prove to have pretty amazing effects. But don’t try this at home… stick to building toy rockets and drones for your science experiments…

Apparently Timothy Leary was right: psychedelic drugs change the way users think. For a long time, possibly forever. In his pioneering work, The Psychedelic Experience (1964), Leary wrote

A psychedelic experience is a journey to new realms of consciousness. The scope and content of the experience is limitless, but its characteristic features are the transcendence of verbal concepts, of space-time dimensions, and of the ego or identity. Such experiences of enlarged consciousness can occur in a variety of ways: sensory deprivation, yoga exercises, disciplined meditation, religious or aesthetic ecstasies, or spontaneously. Most recently they have become available to anyone through the ingestion of psychedelic drugs such as LSD, psilocybin, mescaline, DMT, etc. Of course, the drug does not produce the transcendent experience. It merely acts as a chemical key — it opens the mind, frees the nervous system of its ordinary patterns and structures.

He also said in a 1966 CBS documentary about his work,

We always have urged people: Don’t take LSD unless you are very well prepared, unless you are specifically prepared to go out of your mind. Don’t take it unless you have someone that’s very experienced with you to guide you through it. And don’t take it unless you are ready to have your perspective on yourself and your life radically changed, because you’re gonna be a different person, and you should be ready to face this possibility.

A story in Wired Magazine about this new research described the image above:

A representation of that is seen in the image above. Each circle depicts relationships between networks—the dots and colors correspond not to brain regions, but to especially connection-rich networks—with normal-state brains at left, and psilocybin-influenced brains at right…
In mathematical terms, said Petri (study co-author Giovanni Petri, a mathematician at Italy’s Institute for Scientific Interchange), normal brains have a well-ordered correlation state. There’s not much cross-linking between networks. That changes after the psilocybin dose. Suddenly the networks are cross-linking like crazy, but not in random ways. New types of order emerge…
Petri notes that the network depiction above is still a simplified abstraction, with the analysis mapped onto a circular, two-dimensional scaffold. A truer way of visualizing it, he said, would be in three dimensions, with connections between networks forming a sponge-like topography.

Words, Your Brain and Sex


Naked readingOne of the reasons I’m a dedicated librocubularist* can be found in a story on IFL Science that is headlined, “Learning New Words Activates The Same Brain Regions As Sex And Drugs.” It opens:

While it doesn’t get much better than sex and drugs for many out there, new research has found that simply learning a new word can spark up the same reward circuits in the brain that are activated during pleasurable activities such as these. No wonder there are so many bookworms and scrabble addicts out there.

So nothing like a good, brisk read through the Compact English to get in the mood, eh? Get all purfled from the effort of learning new words. While you groak your snoutfair mate and suggest she festinate her reading while she tells you to be testudineous while she deliciates her words…

The actual article this story draws from doesn’t exactly say that learning new words is the same as sex or drugs. What it says is that learning them lights up the regions of the brain that kicks into play when it wants to reward you. At least it works on people who were being studied under MRIs, not necessary those in libraries or bookstores. Don’t go ecstasiated over it, yet.

It does the same thing for gambling, although I have to admit for this unrepentant mumpsimus, my own reward-centre connection for learning kicks a much more powerful punch than that for gambling. It’s a burden I bajulate well, though.

“A” Personalities: A Theory


GoodreadsWhen someone tells me he is an “A-type” personality, I cannot help but think of the title of Aaron James’ bestselling book: Assholes *A Theory (Anchor Books, New York, 2014). After all, what else would the “A” stand for when someone boasts to the audience he is an alpha male as if the rest of the room was full of less-worthy betas?

Self aggrandizement is not limited, of course, to assholes, but they certainly occupy centre stage (at least in their own mind). Not always the best place to be, considering that, medically speaking, A-types are more prone to heart disease than B-types.

As Wikipedia tells us, Type A personalities are,

“…ambitious, rigidly organized, highly status-conscious, sensitive, impatient, take on more than they can handle, want other people to get to the point, anxious, proactive, and concerned with time management… often high-achieving “workaholics” who multi-task, push themselves with deadlines, and hate both delays and ambivalence.
…Type A behavior is expressed in three major symptoms: (1) free-floating hostility, which can be triggered by even minor incidents; (2) time urgency and impatience, which causes irritation and exasperation usually described as being “short-fused”; and (3) a competitive drive, which causes stress and an achievement-driven mentality.

Not entirely flattering a description, is it? Rigid, status-conscious, ambivalent, impatient, short-fused, irritable, hostile, competitive… not the sort of person you want at a council table where cooperation, consensus and respect make for good governance. A-types at the table generally are seen by others as assholes. Hence the mnemonic association with the book. One wonders why anyone would boast of this.

Aaron James writes of a dichotomy between cooperative people and these A-types:

Even the “bright-line” rules of cooperation will have exceptions and cooperative people often put a certain amount of work into discerning both the spirit of the law and what is finally acceptable in a particular case. They thus seek clarification, check assumptions, ask permission or at least take a measure of care in good faith. The asshole, by contrast sees little need for the work of mutual restraint aimed at benefit for all involved. According to his generalized sense of entitlement, it is only natural that the various advantages of social life should flow his way.

(For the sake of politeness and civility, I am inclined to find another name for assholes. I cannot merely call them jerks, because James differentiates between assholes and mere jerks. Twits, idiots, dweebs, boors, shmucks, cads, jackanapes… these names fail to capture the essence of those truly despicable people whom James describes. I think I will have to simply refer to them as “a*holes” so as not to entirely dilute the impact.)

A-type, A*holes, pretty much the same thing, at least as far as I can fathom. Of course, I’m not a psychologist and I’m sure there are subtle shades of difference I fail to discern.

B-type personalities, on the other hand, Wikipedia says, work well together:

…generally live at a lower stress level and typically work steadily, enjoying achievement but not becoming stressed when they do not achieve. They may be creative and enjoy exploring ideas and concepts. They are often reflective…

Sounds like someone much easier to get along with in a group dynamic like the council table: unstressed, creative, exploratory, reflective. People who will contribute rather than control, will think rather than merely act. People you can work with and respect. people who use “we”  when describing accomplishments and work as a team. People unlikely to be described in James’ book.

A-types, however, will find themselves in it.

The Utility Animal


In the July/August edition of Pets Magazine (the Cat Care issue) there are two articles that caused me concern. One is “The Loyalty and Bravery of a Cat” (p.28), the other is “Quick-Thinking Cat Saves the Day.” (p.26). The latter is a pet profile from the Purina Hall of Fame that honours pets for “extraordinary actions.” The former is about a YouTube video showing a family cat attacking a dog that had itself attacked the family’s four-year-old son.

The acts themselves and the cats involved are extraordinary and deserving of praise as individual animals. But the idea that cats in general need to be propped up as utility animals, that in order to have intrinsic value they need to perform some service for humans, bothers me deeply.

It also annoys me that cat lovers feel the need to be defensive about cats and find ways to make them seem more like dogs. They are separate species with very different social (pack) cultures and cannot be expected to behave like one another.

All animals evolved to fulfill their own purpose. Some have become domesticated through their interactions with humans; a few are even companion animals we call pets. Dogs and cats top that small list. And a small percentage of those perform acts that are of use or beneficial to humans.

Valuing an animal on the basis of its utility is to devalue the life of that animal. Animals do not exist to serve human needs. Yes, they can be trained to perform tasks, but that isn’t their purpose.

Cats have value simply by being cats. All life has its own inherent value and we cannot measure that value against its usefulness to our lives. Not should not – cannot. There is no appropriate measuring stick.

Any attempt only promotes subjective value judgments over other species. It’s akin to measuring the distance to a neighbouring planet by the number of bicycle lengths between us. Irrelevant.

Value your pet, value all life, for what it is. Not what use, not what advantage and not what profit you can gain from it. And I am happy to share my home with my pets for the sake of their companionship alone.

Tricks of the mind


Reading

Reading involves bit of trickery. Mental trickery. It engages the imagination and fools us into thinking we are there within the book: nestled beside the author, or better yet, beside the characters. Immersed in the created world, floating through it like a ghost in a haunted house movie, or perhaps in the imagined flesh, interacting on the mental stage.

We ask ourselves how we would play the scene, how we would decide, take action, engage the other characters. How would we behave at the dinner table with Becky and Rawdon? Would we defend Nancy from the rages of Bill Sykes? Would we warn Caesar on the steps of the forum? How would we greet Paul Atreides in a dusty sietch? Would we hide or expose Jean Valjean?

Our minds put us there, let us explore and build the what-if world of our own thoughts. Every paragraph opens another possibility, and our minds add it to the infinite number of scenarios we play out in them.

We imagine the walls, the furniture, the coolness of the water, the scent of spice on the breeze, the rustle of the leaves as we snake along the forest trail. Our brains get into high gear, populating the microcosm and making it real. We feel the stiffness of the starched collar, the smoothness of the velvet, the coolness of the rain as it soaks our clothes, the heat of the sun on the beach. We see the wallpaper as the sun moves across it, taste the soup served at the table, smell the lavender as we walk in the fields.

Imagination is such a powerful force that it can affect us like the real thing. We get a jolt from the coffee the hero drinks, we get aroused by the imagined sexual touch of the heroine. Our own hearts beat faster as the protagonist runs away in fear from the killer, our hair prickles when she enters the darkened room to confront the danger.

As A Scribbler’s Dreams says:

The curse of a voracious reader is having an amazing imagination. Having an amazing imagination that you feed by reading more and more books and picturing each world vividly. From the power vibrating in the Elder Wand to the smoke curling from Smaug’s nostrils, you, the reader, can picture each world and be sucked in – the only problem is that you can’t physically go there and talk to Liz Bennet or Peter Pevensie or Percy Jackson, no matter how hard you wish.

When good people do bad things in groups


Mob MentalityThe headline is taken from a piece on Science Daily on a study about how groups change personal behaviour and morality. The study is reported on the MIT website. I’ve seen that change myself, many times over the years, and most recently locally. The study adds intelligence on the neurology of how such group activity changed people.

The report itself is called “Reduced self-referential neural response during intergroup competition predicts competitor harm,” which of course would have most people’s eyes glazing over. But the authors of the report start by asking a salient question:

Why do interactions become more hostile when social relations shift from “me versus you” to “us versus them”? 

Why, indeed? Why do people who seem rational and even friendly individually become angry bullies in a group?The authors themselves offer a hypothesis:

One possibility is that acting with a group can reduce spontaneous self-referential processing in the moral domain and, in turn, facilitate competitor harm. We tested this hypothesis in an fMRI experiment in which (i) participants performed a competitive task once alone and once with a group; (ii) spontaneous self-referential processing during competition was indexed unobtrusively by activation in an independently localized region of the medial prefrontal cortex (mPFC) associated with self-reference; and (iii) we assessed participants’ willingness to harm competitors versus teammates. As predicted, participants who showed reduced mPFC activation in response to descriptions of their own moral behaviors while competing in a group were more willing to harm competitors. These results suggest that intergroup competition (above and beyond inter-personal competition) can reduce self-referential processing of moral information, enabling harmful behaviors towards members of a competitive group.

That’s fairly technical and likely not eyebrow-raising for us non-techies. Is this relevant to you and me, to our neighbours and friends and our daily lives? Yes, and very much so.

It means that our personal moral compass may not work, may be disabled when we interact in groups that identify an us-them dichotomy, or see outsiders as competitors. It explains why groups can become uncivil, nasty, aggressive, even violent although their individual members may not be.

It also suggests that to break away from group dominance, one needs to become introspective about our own values and ethics, and one must work hard to recover that moral compass.

We only need read the stories of the brave but estranged family members the late Fred Phelps, leader of the hate-filled Westboro Baptist Church, who broke away from his control. Twenty-three-year-old Zach Phelps-Roper broke from the church recently, and spoke to the Topeka Capital-Journal about his decision:

Empathy and unconditional love, he said, are the keys to solving the world’s problems — a lesson he has learned contrasting his time inside the WBC compound and the past nearly 11 weeks outside it.
“I feel like I have unconditional love for every person around the world,” Phelps-Roper said Friday. “The Westboro Baptist Church sees things differently than I do now.”
The church he grew up in was too busy pointing out problems to look for solutions, he said. He has been able to spend the past two months investigating the second part of that equation.
His conclusion: “Most problems come from a lack of understanding of how we affect other people and things around us. I feel like I have found the holy grail, the overarching solution to solving all of our society’s problems, and I want to learn more. I want to do more.”

What is interesting to me is that Zach, although he broke from the abusive church and its leader, and rediscovered his own moral compass, he also retains considerable religious faith – even a fundamentalist view I would have expected him to abandon. So one can break free of a group’s dominance yet retain shared core beliefs., just behave differently – more normally, more civilly.

That was eye-opening. It certainly isn’t the experience of all Westboro members who have freed themselves of its grip (read this piece about another family member’s struggle; Libby Phelps-Alvarez), although most have said in the interviews I’ve read they are kinder, gentler, more empathetic and humane since leaving the church. I expect most people who break free of any group’s control feel that way.
