The expertise account, or, why the brain’s face-recognition area can be activated by the sight of a chessboard
In a 2017 article on the chess website chessable, entitled “Beating Magnus after a month of training: the neuroscience of why learning chess is so much harder than learning a language”, author David Karmaley writes: “A fascinating finding from neuroscience is that your brain starts using the fusiform face area to store chess positions! This is the part of the brain usually responsible for human face recognition.”
Karmaley seems surprised that a part of the brain associated with face recognition is also used to recognize the positions of pieces on a chessboard, and at first glance, the connection may seem puzzling. But a theory known as the expertise account offers a highly plausible explanation. (more…)

The combined effects of meditation and magic mushrooms
Today I want to tell you about a study entitled “Psilocybin-assisted mindfulness training modulates self-consciousness and brain default mode network connectivity with lasting effects,” which a research team from the University of Zurich published in the journal NeuroImage in August 2019. As the title suggests, this study combined two methods of modulating the brain: engaging inmindfulness meditation and taking the hallucinogen psilocybin, a psychoactive molecule found in “magic mushrooms”. Previous studies had shown that both of these methods produced a similar effect: they gave subjects the impression that the boundaries between their bodies and their environments were dissolving (a state of consciousness often referred to as ego dissolution). But in this study, the research team wanted to find out whether combining these two methods might make this effect stronger and longer-lasting. (more…)
