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. [10] Therefore, the set of anatomical structures considered part of the limbic system is controversial.
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
The theory asserts that the thalamic region is the brain area responsible for emotional responses to experienced stimuli. [ 7 ] Cannon summarises the observations that serve as the basis for his theory of emotion which claims the thalamic region is the coordinating center for emotional reactions. [ 14 ]
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.
The hippocampus is anatomically connected to parts of the brain that are involved with emotional behavior, including the septal area, the hypothalamic mammillary bodies, and the anterior nuclear complex in the thalamus. MacLean proposed that the associated structures of the limbic lobe be included in what he termed as the limbic system. [14]
An imbalance between the relative influence between the emotional and executive systems is posited to be responsible for the heightened levels of risk-taking and emotionality observed in adolescents. Specifically, dopamine-rich regions related to motivation, including the ventral striatum which has been shown to represent the appetitive value ...
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 ...
