Cognitive-Emotional Interactions in the Brain!

In chapter 14 of our physiological psychology Brain and Behavior book it talks about how do we learn and remember. Both are connected. Learning is the change in an organism’s behavior as a result of experience. Memory is the ability to recall or recognize those previous experiences. In  the article Cognitive-Emotional Interactions in the Brain goes in depth on how emotional interactions on the brain correlates with our learning and memory. The article researches that   Emotion and cognition are mediated by separate but interacting systems of the brain. The core of the emotional system is a network that evaluates (computes) the biological significance of stimuli, including stimuli from the external or internal environment or from within the brain (thoughts, images, memories). The computation of stimulus significance takes place prior to and independent of conscious awareness, with only the computational products reaching awareness, and only in some instances. The amygdala may be a focal structure in the affective network. By way of neural interactions between the amygdala and brain areas involved in cognition (particularly the neocortex and hippocampus), affect can influence cognition and cognition can influence affect. Emotional experiences, it is proposed, result when stimulus representations, affect representations, and self representations coincide in working memory.
