#Stories and the Brain: The Neuroscience of Narrative by Paul B. Armstrong, 2020

This book explains how the brain interacts with the social world—and why stories matter.
How do our brains enable us to tell and follow stories? And how do stories affect our minds? In Stories and the Brain, Paul B. Armstrong analyzes the cognitive processes involved in constructing and exchanging stories, exploring their role in the neurobiology of mental functioning.

Armstrong argues that the ways in which stories order events in time, imitate actions, and relate our experiences to others' lives are correlated to cortical processes of temporal binding, the circuit between action and perception, and the mirroring operations underlying embodied intersubjectivity. He reveals how recent neuroscientific findings about how the brain works—how it assembles neuronal syntheses without a central controller—illuminate cognitive processes involving time, action, and self-other relations that are central to narrative. An extension of his previous book, How Literature Plays with the Brain, this new study applies Armstrong's analysis of the cognitive value of aesthetic harmony and dissonance to narrative. Armstrong explains how narratives help the brain negotiate the neverending conflict between its need for pattern, synthesis, and constancy and its need for flexibility, adaptability, and openness to change. The neuroscience of these interactions is part of the reason stories give shape to our lives even as our lives give rise to stories. Taking up the age-old question of what our ability to tell stories reveals about language and the mind, this truly interdisciplinary project should be of interest to humanists and cognitive scientists alike.

Next was an excellent discussion on representations in minds and brains on the Brain Inspired podcast with Luis Favela, Edouard Machery, Frances Egan, Rosa Cao, and John Krakauer. After reviewing the results of a survey showing  a lack of consensus in the neuroscience field around the term "representation," the conversation shifts to the essence of its different meanings and implications for the field and beyond.

Self-Powered Synapse Brings Human-Like Vision to AI Devices

neurosciencenews.com/ai-synaps

Researchers have developed a self-powered artificial synapse capable of color recognition with near-human precision. Unlike traditional systems that demand external energy and massive data processing, this device mimics biological vision and generates its own electricity using solar cells. …

I continue to struggle through Gödel, Escher, Bach: an Eternal Golden Braid by Douglas Hofstadter. It is full of brilliant insights that seem logical to me. Hofstadter is a brilliant author and much smarter than me. But, I do usually disagree with something in each book that I read, and I did read something I think is incorrect. Hofstadter writes, “Bees and other insects do not seem to have the power to generalize—that is, to develop new class symbols from instances which we would perceive as nearly identical.” This is from a section where he writes about the human brain being able to create mental symbols to represent “classes” of things (e.g., cars) and more specific “instances” of things (e.g., Ford cars).

It has been known since at least the early 1900s (Charles Henry Turner 1867-1923) that insects can sometimes change their food sources to survive under environmental pressures. This suggests an ability to recognize new classes (e.g., foods) and even new instances (e.g., flowers). When an invasive insect is introduced to the U.S. by crossing the Atlantic on a ship, it has to adapt to food sources it has never before encountered and many pest insects have unfortunately been able to do so successfully. I doubt those insects just randomly chewed on rocks and other inedible objects until they stumbled across something edible. Someone correct me if I am wrong.

Why Some Individuals Adapt to Fear Faster Than Others

neurosciencenews.com/fear-adap

A new study has uncovered the brain circuits responsible for individual differences in how animals adapt to repeated visual threats. Using advanced neural recording and manipulation tools, researchers identified two distinct pathways in the brain that drive either persistent escape or rapid habituation in mice. …
