The Nucleus accumbens and the Amygdala are the part of the Limbic System.
What is the Limbic System?
The limbic system is the part of the brain involved in behavioral and emotional responses, especially when it comes to behaviors that is required for survival ,feeding, reproduction and caring for our young, and fight or flight responses.
The limbic system is located within the cerebrum of the brain, immediately below the temporal lobes, and are buried under the cerebral cortex (the cortex is the outermost part of the brain).
Limbic system comprises of:
- Limbic cortex
- Hippocampal formation
- Amygdala
- Septal area
- Hypothalamus
What is Nucleus Accumbens?
The nucleus accumbens is a region in the basal forebrain rostral to the preoptic area of the hypothalamus.
The nucleus accumbens has a significant role in the cognitive processing of motivation, aversion, reward , and reinforcement learning hence, it has a significant role in addiction.
In addition, part of the nucleus accumbens core is centrally involved in the induction of slow-wave sleep. The nucleus accumbens plays a lesser role in processing fear (a form of aversion), impulsivity, and the placebo effect. It is involved in the encoding of new motor programs as well.
What is Amygdala?
The amygdala is an almond-shaped structure, located right next to the hippocampus.
The main function of the amygdala is in emotional responses, including feelings of happiness, fear, anger, and anxiety.
This area is also key for the formation of new memories. The amygdala interacts with the hippocampus by attaching emotional content to memories.
It has a role in how memorable memories can be – memories that have strong emotional components tend to stick, rather than those with little emotional content. ‘Fear learning’ is also an element of the amygdala.
Damage to the amygdala can result in more aggression, irritability, loss of control of emotions, and deficits in recognizing emotions, especially recognizing fear.
There are also links of amygdala differences in those with Autism, depression, posttraumatic stress disorder, and bipolar disorder.
