The why of emotion, from whence did it come?

A recent article positing a theory for the origin of emotions as a system to induce cooperation got me to thinking about this subject which I've been mulling for quite some time recently in an effort to understand the requirements for building a truly stable Artificial Intelligence. A post from a few months back covers how emotion once emerged is used to tie emotional import to newly sensed memories while comparing those sensations to previously stored memories and the associated emotional triggers to them. Conditions like Kapgras syndrome highlight the unique role that deep brain regions like the hippocampus and the amygdala play in tying emotion to memory. The new study however knocks at the heart of the question, why do we have emotion in the first place? Why did it evolve? What necessity did it serve? Fundamentally, we should be able to agree that our emotional system emerged to trigger the individual as to important occurrences in the surrounding, to serve as a stimulant to a...

Emotion no longer has to be our guide?

Two recent discussions I've engaged in on Facebook have elicited more thought on the subject of how the human brain ties together emotion to memory. A study released recently showed that an emotional component could be untied or subtracted from the associated sensory experience or memory under current retrieval if a stimulus is provided at a given time. This discovery hints at some amazing possibilities for how the human brain works and helps point to a possible hypothesis for the purpose of emotion in the evolutionary history of the brain. The new frontier of brain science We know today loosely that the neocortex is responsible for processing and relating sensory input (between adjacent senses) we know that "adjacent" is more than an abstract categorization of their hierarchy in the mind but is quite literal, when flattened out the surface consists of patches of cells devoted to processing various types of sensory input in several layers (5 or 6)...where their edged tou...
