A simple view of the information processing through the amygdala follows as: the amygdala sends projections to the hypothalamus, septal nuclei and BNST (via the amygdalofugal tract), the dorsomedial thalamus (via the amygdalothalamic tract), the nuclei of the trigeminal nerve and the facial nerve, the ventral tegmental area, the locus coeruleus ...
The amygdala connects to the thalamus both through the amygdalofugal pathway and through a direct connection to the dorsomedial nucleus of the thalamus. [13] After leaving the substantia innominata , the ventral amygdalofugal pathway continues on a medial path to enter the septal region, the lateral preoptic area , the hypothalamus , and the ...
Besides memory, the amygdala also seems to be an important brain region involved in attentional and emotional processes. First, to define attention in cognitive terms, attention is the ability to focus on some stimuli while ignoring others. Thus, the amygdala seems to be an important structure in this ability.
The stria terminalis (or terminal stria) is a structure in the brain consisting of a band of fibers running along the lateral margin of the ventricular surface of the thalamus. Serving as a major output pathway of the amygdala, the stria terminalis runs from its centromedial division to the ventromedial nucleus of the hypothalamus.
An amygdala hijack is an emotional response that is immediate, overwhelming, and out of measure with the actual stimulus because it has triggered a much more significant emotional threat. [1] The term, coined by Daniel Goleman in his 1996 book Emotional Intelligence: Why It Can Matter More Than IQ , [ 2 ] is used by affective neuroscientists ...
The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.
The anterior part of the insula is subdivided by shallow sulci into three or four short gyri.. The anterior insula receives a direct projection from the basal part of the ventral medial nucleus of the thalamus and a particularly large input from the central nucleus of the amygdala.
Major glutamatergic inputs to the nucleus accumbens include the prefrontal cortex (particularly the prelimbic cortex and infralimbic cortex), basolateral amygdala, ventral hippocampus, thalamic nuclei (specifically the midline thalamic nuclei and intralaminar nuclei of the thalamus), and glutamatergic projections from the ventral tegmental area (VTA).
