The amygdala has the following functions: to value the emotional meaning of the experiences and to coordinate the somatic expression . The amygdala is recognized as a component of a group of brain structures referred to collectively as the limbic system, and is thought to play important roles in emotion and behavior. Further, decreased amygdala activation to sad faces predicts lower internalizing symptoms. Amygdala volume (n = 49) and signal change (n = 44) during emotional face processing were compared between groups, and structure-function correlations were examined within the BD group (n = 16). Here, we consider the possibility that associations among amygdala volume, responses to social hierarchy and political conservatism may be due in part to individual variability in the motivation . Integration of emotions and autonomous responses. The medial amygdala (MA) is a complex amygdaloid structure that is both part of the "extended amygdala" and a key node in the social behavior network. The world "hippocampus" is derived from the Greek words "hippos" meaning horse and "kampos" meaning sea monster, and refers to the structure's shape resembling a seahorse.

Certain structures of the limbic system are involved in memory, as well: two large limbic system structures, the amygdala and the hippocampus, play important roles in memory.The amygdala is responsible for determining which memories are stored and where the memories are stored in the brain.It is thought that this determination is based on how large an emotional response an event invokes.

The amygdala is a limbic system structure that is involved in many of our emotions and motivations, particularly those that are related to survival. The amygdala is specialized for input and processing of emotion, while the hippocampus is essential for declarative or episodic memory.

As mentioned, the amygdala is a complex structure and vital for survival, participating and being linked in a large number of psychological and physiological phenomena . Interestingly, there is preliminary evidence suggesting that alterations in amygdala structure and function may even be present in individuals with the permutation (Hessl, et al., 2007; Moore, et al., 2004). Each amygdala is located close to the hippocampus, in the frontal portion of the temporal lobe. Particularly prominent have been studies of humans that have reported positive correlations between social function (e.g. 15 Followers. Dysfunction of the amygdala results in syndromes ranging from . Save to Library. The amygdala is primarily involved in the processing of emotions and memories associated with fear. 25 Here, . Results: Adolescents with BD showed decreased amygdala volume (p =.009) and increased amygdala response to emotional faces (p =.043). . The amygdala is an almond-shaped structure deep within the temporal lobe and was first identified by Burdach in the early 19th century. amygdala, region of the brain primarily associated with emotional processes. Burdach originally described a group of cells that are now known as the basolateral complex. Introduction. Papers; People; Synapse-specific reconsolidation of distinct fear memories in the lateral amygdala.
