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 ...
Limbic resonance is the idea that the capacity for sharing deep emotional states arises from the limbic system of the brain. [1] These states include the dopamine circuit-promoted feelings of empathic harmony, and the norepinephrine circuit-originated emotional states of fear, anxiety and anger.
The common practice of calling brain circuits that detect and respond to threats "fear circuits" implies that these circuits are responsible for feelings of fear. LeDoux has argued that so-called Pavlovian fear conditioning should be renamed Pavlovian threat conditioning to avoid the implication that "fear" is being acquired in rats or humans.
However, most of its putative role in emotion was developed only in 1937 when the American physician James Papez described his anatomical model of emotion, the Papez circuit. [37] The first evidence that the limbic system was responsible for the cortical representation of emotions was discovered in 1939, by Heinrich Kluver and Paul Bucy.
An example of a neural circuit is the trisynaptic circuit in the hippocampus. Another is the Papez circuit linking the hypothalamus to the limbic lobe. There are several neural circuits in the cortico-basal ganglia-thalamo-cortical loop. These circuits carry information between the cortex, basal ganglia, thalamus, and
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. The general purpose of emotions is to ...
A motor circuit originating in the supplementary motor area, motor cortex, and somatosensory cortex, which in turn projects to the putamen, which projects to the ventrolateral GPi and caudolateral SNr, before returning to the cortex via the ventralis lateralis pars oralis and ventralis lateralis pars medialis.
The brain is made up of two halves. Every half's amygdala is made up of a small, round structures located closer to the forehead than ( anterior to) the hippocampus , near the temporal lobes . The amygdalae are involved in detecting and learning which parts of our surroundings are important and have emotional significance.
