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!

Microscopic Synapses and Giant Microscopes

More and more courses are being offered for free online by prestigious universities. Many of these courses deal with various aspects of the cognitive sciences. One such course is “The Fundamentals of Neuroscience”, from Harvard University (see first link below). This course includes various multimedia features, including an excellent 30-minute documentary video entitled “Connectomics: Big Microscopes & Tiny Synapses” (second link below). This video presents the research being done by Professor Jeff Lichtman and his colleagues in his laboratory, who are using images of real human brains to try to map the connections between their neurons—the synapses.

The Physiology of Expanded Consciousness

The results of some studies are exactly what you would have predicted, but that doesn’t make them any less interesting. For example, the study reported in the link below found that taking psilocybin (the psychoactive substance in “magic mushrooms”) puts the brain in a state that is conducive to freer associations, somewhat as in dreams.

The McGurk Effect: An Auditory Illusion

This week’s post will be brief, so that you can get out and enjoy the start of summer and the restoratjve effects of nature, but the subject is very intriguing.

Have you ever heard of the McGurk effect? It’s an auditory illusion that shows just how much our brains construct our auditory perceptions not only from what we hear but also from what we see.

In the case of spoken words, what we see is the mouth of the person who is talking to us. (more…)

The Evolution of Language, From Animals to Analogy

Language is a communication tool that relies very heavily on analogy. In fact, according to Douglas Hofstadter and Emmanuel Sander, authors of Surfaces and Essences: Analogy As the Fuel and Fire of Thinking (2013), analogy plays a fundamental role in the very way we think.

Hofstadter now admits that when he wrote his book Gödel, Escher, Bach: An Eternal Golden Braid, which is full of daring analogies and became something of a cult in the 1980s, he had not really explored all the implications of analogy as a way of transferring knowledge from one field to another. Today, however, he regards analogy as central to all human experience. (more…)

Preserving Our Bodies and Minds from the Ills of Civilization

For several hundreds of thousands of years, human beings lived and evolved in small groups of hunter-gatherers whose environment was the natural world. It is only for the past 10,000 years or so that we have lived first in villages, and then in cities. Today, a large proportion of us live in megalopolises and work in factories or offices where we have little contact with nature. And what is worse, our contacts with one another are becoming more and more virtual, and our emotional bonds weaker and weaker.

Thus, over what is a very short timespan from an evolutionary standpoint, the human body and the human brain, shaped by a natural environment very different from our own, have had to adapt to a very radical change in environment. And, it would seem, the further our urban way of life departs from the ways of our hunter-gatherer ancestors, the more our physical and mental health suffers.

That is the argument made by John Ratey, co-author of the book Go Wild: Free Your Body and Mind from the Afflictions of Civilization, in an interview by Ginger Campbell in the last episode of his podcast Books and Ideas. (more…)
