The amygdala is one of the best-understood brain regions with regard to differences between the sexes. The amygdala is larger in males than females, in children aged 7 to 11, [17] adult humans, [18] and adult rats. [19] There is considerable growth within the first few years of structural development in both male and female amygdalae. [20]

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 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 ...
The word is derived from the Latin word amygdala, meaning "almond tree", and the Greek word αμυγδαλή, meaning "almond" – reflecting the typical shape of an infilled vesicle. Amygdule is more common in American usage, while amygdale is more common in British usage.
Amygdalotomy, also known as amygdalectomy, is a form of psychosurgery which involves the surgical removal or destruction of the amygdala, or parts of the amygdala.It is usually a last-resort treatment for severe aggressive behavioral disorders and similar behaviors including hyperexcitability, violent outbursts, and self-mutilation.
The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus.Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum.
