A top-down, bottom-up model of circuit function for anxiety and depression.
A great review article describes the bottom-up and top-down processing from Marr’s computational-algorithmic-implementation perspective to understand depressive and anxious disease states. The review illustrate examples of bottom-up processing as basolateral amygdala signaling and projections and top-down processing as medial prefrontal cortex internal signaling and projections. Understanding these internal processing dynamics can help us better model…

“Fitness” Beats “Truth”
The “Fitness-Beats-Truth Theorem” provides a quantitative measure of the extent to which the fitness-only strategy dominates the truth strategy, and of how this dominance increases with the size of the perceptual space. The FBT Theorem supports the Interface Theory of Perception. The Interface Theory of Perception is discussed and described in detail in 2015 by…

Legs move, thoughts flow : Physical exercise influences creative thinking
I only give a summary of the article, lacking the capability to understand and read the native language. Still, the summary is very interesting: Creative thinking is the ability to generate novel and useful solutions to a problem, of which divergent and convergent thinking are two common types. Evidence shows that physical exercise may influence…
