The amygdala is a fascinating, complex structure that lies at the center of much of our current thinking about emotion. Here, I will review data that suggest that the amygdala is involved in several processes linked to determining what a stimulus is and what the organism should therefore do – the two questions that are part of the title.
Apr 13, 2020 · Campeau, S. & Davis, M. Involvement of subcortical and cortical afferents to the lateral nucleus of the amygdala in fear conditioning measured with fear-potentiated startle in rats trained ...
Mar 11, 2023 · The MRI data were segmented into the whole amygdala and nine amygdala nuclei groups, accessory basal nucleus, anterior amygdaloid area-AAA, basal nucleus, central nucleus, cortical nucleus ...
The amygdala is a collection of nuclei found deep within the temporal lobe. The term amygdala comes from Latin and translates to "almond," because one of the most prominent nuclei of the amygdala has an almond-like shape. Although we often refer to it in the singular, there are two amygdalae —one in each cerebral hemisphere.
Oct 30, 2023 · The nucleus accumbens in turn sends efferent projections to the midbrain, hypothalamus, amygdala, nuclei of the brainstem, and the globus pallidus. The nucleus accumbens, through these broad connections mediates several of its functions. For example, the VTA has been shown to play a key role in reward processing.
May 31, 2021 · The lateral nucleus (LA) extends across the entire length of the amygdala. It is the largest nucleus of the human amygdala with a high density of nerve cells . The LA is extremely well connected intrinsically (its individual parts are interconnected) as well as with other nuclei of the amygdala, mostly with the basal nucleus .
In this classification, amygdala nuclei are divided into three groups : 1) the deep or basolateral group, which includes the lateral nucleus, the basal nucleus, and accessory basal nucleus; 2) the superficial or cortical-like group, which includes the cortical nuclei and nucleus of the lateral olfactory tract; and 3) the centromedial group ...
