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 support Edelman’s and Tononi’s (2000, p. 83) theory of neuronal group selection (TNGS, aka neural Darwinism).

In preparation for the March meeting topic, Your Political Brain, please recommend any resources you have found particularly enlightening about why humans evolved political thinking. Also, please share references about how brain functions lead to political perceptions. I’m assuming political perceptions result from more fundamental cognitive orientations, and that those arise in part from one’s genetics and in part from environment (during development and afterward).
Let’s use the following description from Wikipedia:
Politics is the process of making decisions applying to all members of each group. More narrowly, it refers to achieving and exercising positions of governance— organized control over a human community, particularly a state. Furthermore, politics is the study or practice of the distribution of power and resources within a given community (this is usually a hierarchically organized population) as well as the interrelationship(s) between communities. (Wikipedia)
This description places political thinking in the realm of the brain’s/mind’s social processing.
Following are some candidate resources for our discussion preparation:
All bodily capacities, including the most impressive, uniquely human cognitive and metacognitive ones, coevolve with regulatory mechanisms. Regulatory mechanisms operate unconsciously, and control the expression of associated capacities such that the latter consistently operate with high effectiveness and efficiency to promote replication of our genes. So, to fundamentally change and render socioecologically sustainable the human species, H+ technologies will somehow have to alter the deep neural relationship between these regulatory “value systems,” (sensu neuroscientist Gerald Edelman in, “A Universe of Consciousness”), residing primarily in the limbic system, and all our mundane or enhanced corticothalamic activities. We need H+ that radically diminishes our transparent penchant for evolutionarily adaptive self-deception, and that alters our power to more freely and consciously choose, moment-to-moment, what we do with our cognitive capacities. I suspect current H+ is blind to this. — Warmly, PJW
