What are the subdivisions of the amygdala?

Amygdala Subdivisions The amygdala complex is traditionally subdivided into thirteen nuclei in three major groups, namely the deep, superficial, and remaining nuclei [Whalen, 2009] (Table ​ 1). The deep group or basolateral complex (BLA) is comprised of the lateral, basolateral, and basomedial nuclei.

What are the functions of the amygdala?

The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.

What are the components of the amygdala?

Anatomy of the amygdala The amygdala comprises a group of nuclei, or clusters of neurons. The basolateral complex, the largest of the clusters and located roughly in the lateral and middle parts of the amygdala, includes the lateral, basal, and accessory-basal nuclei.

What is the function of the amygdala in the experience of emotion?

Along with emotions, the amygdala processes memories. It filters the memories with the different emotional responses involved with the memory. The amygdala decides which memories it will keep and where the brain will store these memories.

What is the midbrain?

The midbrain is the topmost part of the brainstem, the connection central between the brain and the spinal cord. There are three main parts of the midbrain – the colliculi, the tegmentum, and the cerebral peduncles.

What are the functions of the amygdala and prefrontal cortex of the brain?

Amygdala: ↑ The brain structure that actually detects stress and tells the HPA axis to respond. Prefrontal Cortex: ↑ The control center of the brain that controls thoughts and actions. Its main job is to control the emotional responses to stress by regulating the amygdala.

What is the function of the amygdala and hippocampus?

The amygdala is specialized for input and processing of emotion, while the hippocampus is essential for declarative or episodic memory. During emotional reactions, these two brain regions interact to translate the emotion into particular outcomes.

What is parietal lobe function?

The parietal lobes are responsible for processing somatosensory information from the body; this includes touch, pain, temperature, and the sense of limb position. Like the temporal lobes, the parietal lobes are also involved in integrating information from different modalities.

Where is the basolateral amygdala?

The basolateral amygdala (BLA), or basolateral complex, consists of the lateral, basal and accessory-basal nuclei of the amygdala. The lateral nuclei receives the majority of sensory information, which arrives directly from the temporal lobe structures, including the hippocampus and primary auditory cortex.

What is the function of the amygdala in the experience of emotion quizlet?

Terms in this set (4) What does the Amygdala do? It is crucial in processing and regulating emotional reactions. Especially important in strong emotional reactions such as fear and anger.

What is the role of the amygdala in anxiety?

The amygdala is responsible for the expression of fear and aggression as well as species-specific defensive behavior, and it plays a role in the formation and retrieval of emotional and fear-related memories.
