This paper aims to expound more on the Amygdala, the part of the brain that processes emotions. It is an assortment of nuclei that are located within the temporal lobe. Although considered singular, two Amygdalae exist in every cerebral hemisphere (Kanwisher, 2014). The area referred to as the Amygdala incorporates various cerebrum structures with diverse connectional and functional physiognomies in human beings and other organisms. The Amygdala is more centrally and medially positioned and categorized as a section amidst the basal ganglia.
The amygdala is linked with the subcortical brain areas. It connects with various subcortical regions, including the Diencephalon, basal forebrain, and brainstem. Most of the fibers align into the amygdalafugal trail that connects with the globus pallidus (Caplan, 2009). The other fibers are thin and referred to as stria terminalis and take a circuitous dorsal path into the internal capsule. Its projections from the dorsal path ascend from the thalamic nuclei and are next to the subsequent thalamic nuclei.

The amygdala has various functions that occur within the right and left amygdala. The right amygdala is linked with adverse emotions filtering, sorrow, and panic, whereas the left amygdala is linked with contentment. The amygdala function is to encode, store, and deduce emotions (Amaro & Barker, 2006). The amygdala processes fear and dispensation of the fear-inducing inducements. When individuals face an atrocious stimulus, data about that inducement is directly sent to the amygdala, sending indications to the brain zones, such as the hypothalamus, that trigger reaction, such as respiration, to formulate action and elevated heart rate (Leschak et al., 2020). The main reason why I am interested in this section of the brain is that I am a mental health therapist, as it safeguards the key to emotions and memories. Being a mental health therapist requires sufficient knowledge of the amygdala's functioning to give precise and accurate information to clients. Being competent in this area will guarantee efficient service delivery.
