“Foraging Behavior” – The Basis of Business, Econ, Finance, Politics, etc….Evertyhing….

Standard

 

You are sitting on your couch flipping through TV channels trying to decide whether to stay put or get up for a snack. Such everyday decisions about whether to “stay” or to “go” are supported by a brain region called the anterior cingulate cortex (ACC), which is part of the prefrontal cortex.

(This is called..) “foraging behavior”…the firing of two distinct types of inhibitory neurons…has a strong correlation with the start and end of a period of foraging behavior.

…..”The brain is complex and continuously active, so it makes sense that these two types of inhibitory interneurons define the boundaries of a behavior such as foraging, opening and then closing the ‘gate’ within a particular neural circuit through changes in their activity,”

“we have to remain humble about our understanding of the brain, because even our most powerful tools remain pretty blunt instruments for decoding the brain. In fact, we still do not know how to decipher the basic language of how the brain works.”

A few numbers can help to define the challenge. The human brain is thought to have close to 86 billion neurons, each making on average about 10,000 connections. In contrast to most animals, our brains are largely made up of a heavily folded cortex, accounting for 80 percent of brain mass and about 100,000 miles of axons that provide the highways between neurons.1 Continue reading
