Different signaling proteins found instrumental in remembering and forgetting scent-based memories

Different signaling proteins found instrumental in remembering and forgetting scent-based memories

Understanding how brains actively erase memories may open new understanding of memory loss and aging, and open the possibility of new treatments for neurodegenerative disease. http://neurosciencenews.com/memory-brain-signals-8002/ 

Are We Racists?

Are We Racists?

BMAI friends. The following ramble is my first cut at making sense of the grave role racial (and other) bias is playing in the world today. This was prompted by comments I see daily from my family and friends on social media. Thinking about the great lack of self- and group-awareness many of the commenters display, I turned my scope inward. How do my own innate, evolved biases slant me to take my group’s and my own privileges for granted and…

Future discussion topic recommendations

Future discussion topic recommendations

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…

‘Entangled’ consciousness app approaching release

‘Entangled’ consciousness app approaching release

The Global Consciousness Project, Institute of Noetic Sciences (IONS, for which I was once Hawaii state coordinator) and Princeton Engineering Anomalies Research (PEAR) are collaborating to release a smart phone app, Entangled, that aims to Monitor your mind’s influence on your physical environment Let you take part in large-scale consciousness experiments Support ongoing development of a”consciousness technology” platform for developers and artists Monitor global consciousness data in real-time Before you think I’ve gone off the deep end, let me explain that I…

Giant neuron found encircling and intraconnecting mouse brain

Giant neuron found encircling and intraconnecting mouse brain

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…

Computer metaphor not accurate for brain’s embodied cognition

Computer metaphor not accurate for brain’s embodied cognition

It’s common for brain functions to be described in terms of digital computing, but this metaphor does not hold up in brain research. Unlike computers, in which hardware and software are separate, organic brains’ structures embody memories and brain functions. Form and function are entangled. Rather than finding brains to work like computers, we are beginning to design computers–artificial intelligence systems–to work more like brains.  https://www.wired.com/story/tech-metaphors-are-holding-back-brain-research/ 

Mathematical field of topology reveals importance of ‘holes in brain’

Mathematical field of topology reveals importance of ‘holes in brain’

New Scientist article: Applying the mathematical field of topology to brain science suggests gaps in densely connected brain regions serve essential cognitive functions. Newly discovered densely connected neural groups are characterized by a gap in the center, with one edge of the ring (cycle) being very thin. It’s speculated that this architecture evolved to enable the brain to better time and sequence the integration of information from different functional areas into a coherent pattern. Aspects of the findings appear to…
