After providing all the funding for The Brain from Top to Bottom for over 10 years, the CIHR Institute of Neurosciences, Mental Health and Addiction informed us that because of budget cuts, they were going to be forced to stop sponsoring us as of March 31st, 2013.

We have approached a number of organizations, all of which have recognized the value of our work. But we have not managed to find the funding we need. We must therefore ask our readers for donations so that we can continue updating and adding new content to The Brain from Top to Bottom web site and blog.

Please, rest assured that we are doing our utmost to continue our mission of providing the general public with the best possible information about the brain and neuroscience in the original spirit of the Internet: the desire to share information free of charge and with no adverstising.

Whether your support is moral, financial, or both, thank you from the bottom of our hearts!

A Summer School on Animal Sentience and Cognition

Without consciousness the mind-body problem would be much less interesting. With consciousness it seems hopeless.” – Thomas Nagel

What is it like to be a bat? is the somewhat disconcerting title of philosopher Thomas Nagel’s famous 1974 article on the ineffability of subjective consciousness. In reality, we humans will never know what it is like to use echolocation to navigate as we fly through the air, because, unlike bats, we simply don’t have the bodies or the nervous systems to do so. But the question of animals’ experience in general is nevertheless highly relevant, if only because our human species has the faculty of language and has developed a scientific method that lets us make observations and deductions about the mental states of other human beings and other animals. And because humans domesticate, exploit and exterminate thousands of other animal species, knowing what they may experience becomes an ethical imperative to guide the way we treat them.

That was the idea behind a 10-day summer school entitled “The other minds problem: animal sentience and cognition”, presented in 2018 by the Université du Québec à  Montréal Institut des sciences cognitives (UQAM/ISC institute of cognitive science). At this event, some 60 comparative psychologists, ethologists, evolutionary scientists and cognitive neurobiologists made presentations on scientific efforts to understand the thought processes of other animal species. (To watch a video of each presentation, click the preceding link, then click on the presenter’s name.) As the overview of the summer school so nicely put it, these presenters played the role of human spokespersons for elephants, monkeys, whales, cows, pigs, chickens, mice, fish, lizards, lobsters and snails, attempting to communicate in words what science believes it understands about their mental processes.

The UQAM/ISC summer schools are high-profile events that have been held every other year since 2008 (plus the first edition, on categorization, in 2003). They always address sweeping topics: social cognition (2008), the origin of language (2010), evolution and the function of consciousness (2012), the science of the web and the mind (2014) and reasoning (2016).

Are Nationalist Sentiments Inversely Proportional to Cognitive Flexibility?

Many studies have shown how certain emotional characteristics can have higher-level cognitive effects. including an impact on people’s political choices. For example, studies have shown that being more sensitive to disgusting things is correlated with having a more conservative political or ethical outlook. Being afraid of nature or even of hearing someone read horror stories out loud is also likely to attract people to the conservative end of the political spectrum. More recently, the opposite phenomenon has even been demonstrated: making people feel invincible through a simple thought experiment can move them toward the more liberal, progressive end of this spectrum.

Daniel Glaser: A Neuroscientist Who Explains

This week I’d like to tell you about a little gold mine of easy-to-understand explanations of neuroscience. It’s a weekly blog and podcast called “A Neuroscientist Explains”, by Dr. Daniel Glaser, and you can access it on the website of the newspaper The Guardian.

Glaser has had an interesting career as a scientist who always places great emphasis on sharing his knowledge with the general public. He has also taken an interest for many years in the arts and in multidisciplinary approaches—for example, he has conducted studies in which he compared the activation of mirror neurons in the brains of ballet dancers and of practitioners of the Brazilian martial art of capoeira. Glaser is now the director of Science Gallery London, an organization that builds bridges between the arts, the sciences and health through research, experimentation and exhibitions to which the general public is invited.

Pedal Your Way To Healthy Aging!

The evidence of the benefits of physical activity for both the body and the brain continues to pile up. A study published by Pollock et al. in April 2018 dealt with a group of 125 male and female cyclists ages 55 to 79, a stage of life when normally our muscle fibres becomes less vascularized and our immune systems decline. But Pollock found that some of his subjects, at age 75, had the immune profiles of 20-year-olds!

As described in a summary of this study published in the French newspaper Le Monde, these cyclists (two-thirds of whom were men) had all been cycling for many years, still cycled 2.5 hours per week (at moderate but constant intensity) and could cycle 100 kilometres in 6.5 hours. (more…)

A Pickpocket Teaches the Science of Attention

When I give courses on the brain’s “higher functions”, and I get to the topic of attention and control, I often show videos of Apollo Robbins, a professional pickpocket whom many consider the best in the world. The video I show most often was produced by Scientific American and is entitled “Neuroscience Meets Magic”. It shows neuroscientists who specialize in the subject of attention analyzing his subtlest gestures and identifying the classic principles of attention that he is manipulating, such as bottom up, top down, frame of attention, and misdirection.
