Daniel Dennett on the evolution of the mind

Daniel Dennett on the evolution of the mind

Comments 2 comments

The Google talk on his new book, From Bacteria to Bach and Back: The Evolution of Minds. The blurb: “How did we come to have minds? For centuries, this question has intrigued psychologists, physicists, poets, and philosophers, who have wondered how the human mind developed its unrivaled ability to create, imagine, and explain. Disciples of Darwin have long aspired to explain how consciousness, language, and culture could have appeared through natural selection, blazing promising trails that tend, however, to end…

Future discussion topic recommendations

Future discussion topic recommendations

Comments 2 comments

Several of us met on Labor Day with the goal of identifying topics for at least five future monthly meetings. (Thanks, Dave N, for hosting!) Being the overachievers we are, we pushed beyond the goal. Following are the resulting topics, which will each have its own article on this site where we can begin organizing references for the discussion: sex-related influences on emotional memory gross and subtle brain differences (e.g., “walls of the third ventricle – sexual nuclei”) “Are there…

The differences between sitting and moving meditative states

The differences between sitting and moving meditative states

Comments 0 Comment

Here is Thompson’s talk on the topic. As a dancer and martial artist, as well as an embodied cognitioner, this talk is particularly relevant to me. I’ve been saying since forever that these arts are meditative disciplines in themselves. And one doesn’t necessarily need the sitting still sort of meditation to achieve meta-cognition. Having done both kinds my anectodic report is that both sitting and moving meditation induce meta-cognition. But there are no studies on movement meditation to confirm it…

From intersubjectivity to interbeing

From intersubjectivity to interbeing

Comments 1 comment

I was reminded today of this seminal paper by Evan Thompson with the above title. The premise: “Human consciousness is not located in the head, but is immanent in the living body and the interpersonal social world. One’s consciousness of oneself as an embodied individual embedded in the world emerges through empathic cognition of others. Consciousness is not some peculiar qualitative aspect of private mental states, nor a property of the brain inside the skull; it is a relational mode…

There’s no such thing as a male or female brain

There’s no such thing as a male or female brain

See this New Scientist article. Excerpt: When the group looked at each individual brain scan, however, they found that very few people had all of the brain features they might be expected to have, based on their sex. Across the sample, between 0 and 8 per cent of people had “all-male” or “all-female” brains, depending on the definition. “Most people are in the middle,” says Joel. This means that, averaged across many people, sex differences in brain structure do exist,…

Your brain hallucinates your conscious reality

Your brain hallucinates your conscious reality

Comments 1 comment

Ted Talk by neuroscientist Anil Seth. The brain processes the outer world via the senses, then organizes it and projects that organization back on to the world. Perception itself is an active, constructive process. It is a controlled hallucination. Reality is just an agreed upon hallucination. And so is the perception of our self a controlled hallucination.

Giant neuron found encircling and intraconnecting mouse brain

Giant neuron found encircling and intraconnecting mouse brain

Comments 0 Comment

A neuron that encircles the mouse brain emanates from the claustrum (an on/off switch for awareness) and has dense links with both brain hemispheres. Scientists including Francis Crick and Christoph Koch have speculated that the claustrum may play a role in enabling conscious thought. https://www.sciencealert.com/a-giant-neuron-has-been-found-wrapped-around-the-entire-circumference-of-the-brain  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1569501/ (Crick and Koch academic article) We’ve frequently discussed how self-aware consciousness likely arises not from any single brain structure or signal, but from complex, recursive (reentrant), synchronized signaling among many structures organized into functional regions. (Did I get…
