How “awe” contributes to our well-being
In November 2023, many music fans in Quebec and elsewhere were saddened to hear that Karl Tremblay, lead singer of the folk-rock group Cowboys Fringants, had died of prostate cancer at age 47. Many of his fans remembered the moments of magic that they had experienced at the group’s concerts—the feelings of true oneness that only music can provide. People often have similar, fleeting experiences of wonder when out in nature—for example, beholding a beautiful sunset, or a sky full of stars or the view from the top of a mountain—or with the help of magic mushrooms or other psychedelic substances. The term “awe” is often used quite aptly to refer to these experiences when we feel part of something greater than ourselves, with a mixture of admiration and amazement, along with some fear, reverence and respect.

Determined: A Science of Life without Free Will
This week I’d like to tell you about one of my “travelling companions” who has had a huge influence on me for as long as I’ve been writing popular science. His name is Robert Sapolsky, he’s a neurobiologist and primatologist, and I’ve posted about him before here and here. He has just published a new book, Determined: A Science of Life without Free Will , following his earlier, sensational book Behave, published in 2017. (more…)

An interview that capture some of the essential aspects of my book to be published this fall
Today I’d like to tell you about an interview with a researcher whose thoughts run in exactly the same direction as those in the book that I’ve been writing since 2020. This book will be published this fall by
Écosociété. (I don’t know whether I’ve mentioned this book in the English version of this blog before, but it’s being published in French, and if you’re interested and can read French, I’ve been maintaining an “author’s log” about the process of writing it, in the French version of this blog).

The “rich club” of networks in the human brain
What is known as the “rich club” in the human brain consists of densely interconnected regions of neurons that show little plasticity. The activity of these networks is highly stable , and the regions involved are rapidly informed of other neuronal events that occur throughout the brain . The neurons in this “rich club” may be regarded as one end of a continuum in terms of their low plasticity and the many connections that they make with other parts of the brain. The other end of the continuum consists of neurons that show a high degree of plasticity but are connected to relatively few other neurons and have a far lower level of activity. Along this continuum, just about every other possible combination of these traits can be found. It has been estimated, however, that the “rich club”, while accounting for only about 20% of the total population of neurons in the human brain , also accounts for nearly 50% of its total activity !
