Emotional memories are thought to be stored in synapses throughout the brain. Fear memories, for example, are considered to be stored in the neuronal connections from the lateral nuclei to the central nucleus of the amygdalae and the bed nuclei of the stria terminalis (part of the extended amygdala ).
Currently, it is not considered an isolated entity responsible for the neurological regulation of emotion, but rather one of the many parts of the brain that regulate visceral autonomic processes. [9] Therefore, the set of anatomical structures considered part of the limbic system is controversial.
Affective neuroscience is the study of how the brain processes emotions.This field combines neuroscience with the psychological study of personality, emotion, and mood. [1] The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
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 ...
A heuristic model of the neural pathway of the Papez circuit shows the connections between its different parts. Based on Papez's experiment with aggression in rats and other studies, it was initially believed that the circuit was involved with emotion. The circuit connects the hypothalamus and the cortex and acts as the emotional system of the ...
Specifically, they're connected through the Enteric Nervous System, or the ENS, which has over 100 million nerves running directly from your brain ... to your stomach. So emotional distress can ...
Exposure to different types of emotion and levels of arousal also appear to influence pain through an interaction known as the valence-by-arousal interaction. During this reaction, negative emotions experienced by an individual with low levels of arousal tend to cause enhanced pain while negative valenced emotions with higher levels of arousal ...
The cerebellum (Latin for “little brain”) is a distinct part of your brain that is attached to the rest of your brain at the back of your head. The cerebellum is only about one-tenth the size ...
