Algorithm brings whole-brain simulation within reach

Algorithm brings whole-brain simulation within reach

Comments 0 Comment

An improvement to the Neural Simulation Tool (NEST) algorithm, the primary tool of the Human Brain Project, expanded the scope of brain neural data management (for simulations) from the current 1% of discrete neurons (about the number in the cerebellum) to 10%. The NEST algorithm can scale to store 100% of BCI-derived or simulated neural data within near-term reach as supercomputing capacity increases. The algorithm achieves its massive efficiency boost by eliminating the need to explicitly store as much data…

LSD produces new type of harmonic order in the brain

LSD produces new type of harmonic order in the brain

See this study. The blurb: “New brain published in the journal Scientific Reports sheds new light on how LSD produces its psychedelic effects. The drug resulted in the ’emergence of new type of order in the brain,’ the researchers found. The study used a new mathematical method to analyze brain activity, known as connectome-harmonic decomposition, to examine how LSD caused alterations in consciousness. A connectome is a distinctive pattern of neural connections — like a wiring diagram of the brain.”

A Guardian article last October brings the darker aspects of the attention economy, particularly the techniques and tools of neural hijacking, into sharp focus. The piece summarizes some interaction design principles and trends that signal a fundamental shift in means, deployment, and startling effectiveness of mass persuasion. The mechanisms reliably and efficiently leverage neural reward (dopamine) circuits to seize, hold, and direct attention toward whatever end the designer and content providers choose. The organizer of a $1,700 per person event…

Downward mental causation and free will

Downward mental causation and free will

Comments 1 comment

I know, to free will or not to free will, that is the hackneyed question debated in philosophical circles since we learned how to talk. But here’s a cognitive neuroscientist’s research on “how neuronal code underlies top-down mental causation.” It’s a long video, over 2 hours, and I have yet to complete it. Here is Peter Tse’s CV.  Here is his book on the topic is. Here is a good summary of Tse’s work on the topic.

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…

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…

Your brain hallucinates your conscious reality

Your brain hallucinates your conscious reality

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.
