The Neural Basis of Human prosocial behavior

A new Frontiers in Science ebook here. The blurb:

With the rise of laboratory and field experimental economics, the famous prisoner’s dilemma, public good, dictator, ultimatum, and trust games have become the classical paradigms of studying prosocial behavior. Due to the increasing use of functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) with human subjects playing economic games, the neural basis of prosocial behavior has been uncovered by a large amount of neural imaging and stimulating research. A wide range of brain areas including, but not limited to the prefrontal cortex, orbitofrontal cortex, cingulate cortex, striatum and amygdale have been revealed highly correlated or causally related with prosocial behaviors.

A number of hypotheses such as empathy, altruism, reciprocity, inequality aversion, or guilt aversion preferences have been considered as motives promoting prosocial behavior. However, the neural bases of these different preferences have seldom been revealed and the mechanisms of how these preferences influence prosocial behavior have rarely been discussed. Moreover, since prosocial behavior may be due to the cooperative work of several brain areas (neural network), it is essential to integrate findings from difference disciplines including psychology, economics, neuroscience, and to nearly all the social and behavioral sciences.

The present Research Topic of Frontiers in Psychology aims to bring a collection of research revealing the neural basis of human prosocial behavior. Interdisciplinary research investigating brain areas influencing prosocial behaviors is highly encouraged. We believe sharing relevant brain imaging and stimulation findings can promote a better understanding of neural basis of prosocial behavior. 

Fantastic Fungi

Ever since seeing the Spore Drive in Star Trek: Discovery, as well as the story on the Wood Wide Web, I’ve been fascinated by the possibilities for fungi. It’s playing at The Guild Theater Dec. 9 – 12. See the preview below. Here’s the blurb from Rotten Tomatoes on this new documentary:

“Fantastic Fungi, directed by Louie Schwartzberg, is a consciousness-shifting film that takes us on an immersive journey through time and scale into the magical earth beneath our feet, an underground network that can heal and save our planet. Through the eyes of renowned scientists and mycologists like Paul Stamets, best-selling authors Michael Pollan, Eugenia Bone, Andrew Weil and others, we become aware of the beauty, intelligence and solutions the fungi kingdom offer us in response to some of our most pressing medical, therapeutic, and environmental challenges.”

The neuroscience of creativity

Since this came up in our book discussion or Range yesterday,  something relevant from this article. It’s interesting how the salience network mediates between and integrates two normally one on, one off networks.  And how it is the connections between networks that seems to do the trick akin to the book’s description of how those with range make analogous connections between ideas and domains.

“Three of these distinct brain networks — the default mode, the executive control network and the salience network — have been identified by Dr Beaty and colleagues as being associated with creativity.

“The default mode network is activated when people are relaxed and their mind is wandering to different topics or experiences, associated with remembering past experiences, thinking about possible future experience and daydreaming.

“The executive control network comes into play when you need to pay close attention and focus on something in the environment. It comes online when we have to focus our attention and cognitive resources on more demanding tasks that require us to hone our attention and manage multiple things in our mind at one time, directing the content of our thoughts.

“The salience network plays a significant role in detecting and filtering important — or salient — information. It’s called salience because it helps us to pick up on salient information in the environment or internally. Interestingly, the default mode and the executive control networks don’t typically work together — when one network is activated, the other tends to be deactivated. One thing that we think the salience network might be doing is switching between an idea-generation mode, which is more of a default process, and the idea-evaluation mode, which is more of a control way of thinking. […] More creative people tended to have more network connections.”

History of complexity science

Here’s an interesting infographic of the main concepts and thinkers in complexity science across time. Notice S. Kauffman is slated in the 1980s column, suggesting the graphic depicts when influential thinkers first make their marks.

how does music affect the brain?

The blurb:

“In this episode of Tech Effects, we explore the impact of music on the brain and body. From listening to music to performing it, WIRED’s Peter Rubin looks at how music can change our moods, why we get the chills, and how it can actually change pathways in our brains.”

For me the most interesting part was later in the video (10:20), how when we improvise we shut down the pre-frontal planning part of the brain and ‘just go with the flow,’ which is our most creative and innovation moments. This though does depend on having used the pre-frontal cortex in learning the techniques of music to get them so ingrained in memory that we are then free to play with what we’ve programmed.

The info processing (IP) metaphor of the brain is wrong

Psychologist Robert Epstein, the former editor of Psychology Today, challenges anyone to show the brain processing information or data. The IP metaphor, he says, is so deeply embedded in thinking about thinking it prevents us from learning how the brain really works. Epstein also takes on popular luminaries including Ray Kurzweil and Henry Markram, seeing both exemplifying the extremes of wrongness we get into with the IP metaphor and the notion mental experience could persist outside the organic body.

The Empty Brain (Aeon article with audio)

Neuroscience: Deep breathing changes your brain

Humans have some intentional control over our brains (and minds and bodies) and focused breathing is one of those control mechanisms.

“This recent study finally answers these questions by showing that volitionally controlling our respirational, even merely focusing on one’s breathing, yield additional access and synchrony between brain areas. This understanding may lead to greater control, focus, calmness, and emotional control.”

Vibration: A new theory of consciousness

Article in Scientific American. One point. The article sees energetic fields underlying matter as if they are separate things, one the cause of the other. Whereas a naturalistic, postmetaphysical view might be that they mutually entail and co-generate each other within an ecological frame. The cause/effect frame still clings to a form of dualism.

Musk: merging of humans and technology essential to survival

[et_pb_section bb_built=”1″][et_pb_row][et_pb_column type=”4_4″][et_pb_text _builder_version=”3.17.6″]

From Axios interview with Elon Musk:

Musk said his neuroscience company, Neuralink, has about 85 of “the highest per capita intelligence” group of engineers he has ever assembled — with the mission of building a hard drive for your brain.

  • “The long-term aspiration with Neuralink would be to achieve a symbiosis with artificial intelligence.”
  • Wait. What? “To achieve a sort of democratization of intelligence, such that it is not monopolistically held in a purely digital form by governments and large corporations.”
