The neural center in the limbic system that plays a central role in emotions such as aggression and fear is amygdala.
Amygdala
The name "amygdala" relates to the structure's almond-like form.
The left and rightamygdalae, which are situated immediately adjacent to the hippocampus, are crucial to how we react emotionally, including how we feel pleasure, fear, anxiety, and anger.
What is the limbic system?
The limbic system is the area of the brain that controls humanbehavior and emotions, especially when it comes to behaviors like feeding, reproducing, and raising offspring as well as fight-or-flight reactions.
The limbic system's components are hidden deep inside the brain, above the brainstem and below the cerebralcortex.
The hippocampus and the amygdala are two of the limbic system's key components, along with the thalamus, hypothalamus (which produces vital hormones and regulates appetite, thirst, mood, etc.), and basal ganglia (which processes rewards, forms habits, moves, and learns).
