Emotional lateralization is the asymmetrical representation of emotional control and processing in the brain. There is evidence for the lateralization of other brain functions as well. Emotions are complex and involve a variety of physical and cognitive responses, many of which are not well understood.
Temporal cortex – This brain area is important in processing sound, speech, and language use, as well as helping us understand others faces and others emotions based on facial cues. [42] The temporal cortex is responsible for determining the quality and content of our emotional memories.
Emotional arousal has also been shown to cause augmentation in memory, and enhanced processing and information consolidation when paired with stimuli. This effect has been explained by the arousal-biased competition (ABC) model, which postulates that bottom-up sensory preference to arousing stimuli and top-down relevance to current activity or ...
He postulated the limbic system as the brain's center of emotions, including the hippocampus and amygdala. Developing observations made by Papez, he hypothesized that the limbic system had evolved in early mammals to control fight-or-flight responses and react to both emotionally pleasurable and painful sensations.
If the amygdala perceives a match to the stimulus, i.e., if the record of experiences in the hippocampus tells the amygdala that it is a fight, flight or freeze situation, then the amygdala triggers the HPA (hypothalamic–pituitary–adrenal) axis and "hijacks" or overtakes rational brain function. [5] This emotional brain activity processes ...
Human brain in the coronal orientation. Amygdalae are shown in dark red. The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates.
