What is the amygdala

What is an almond shaped part of your brain that is made of 13 nuclei and is next to your hippocampus. The amygdala regulates emotions such as anger, aggression, anxiety, fear, emotional memory, and social cognition. The amygdala lies in the temporal lobe, behind the uncus.

What does the amygdala do?

What is controls emotions such as anger, aggression, anxiety, fear, emotional memory, and social cognition. The amygdala also ties emotional meaning to our memories, reward processing(getting awarded/achievement), and decision-making.

Sections of the amygdala

What is the

• The medial (middle) group of subnuclei which has many connections with the olfactory bulb and cortex (related to olfactory functions, or sense of smell).
• The basolateral group has several connections with the cerebral cortex (outer layer that lies on top of your cerebrum), particularly the prefrontal cortex within the frontal lobes.
• The central and anterior (front) group of nuclei has many connections with the brain stem, hypothalamus, and sensory structures.

200

Limbic system

What is a collection of structures process emotional memory.

300

Where is the limbic system

What is located within the cerebrum , below the temporal lobes, and under the cerebral cortex.

400

Connection

What is thought to be the body's most important element to respond to stress and being connected to endocrine and autonomic nervous system.

500

Limbic cells

Within the limbic system, the cells are either arranged in fewer layers or are more jumbled. As there is less complexity of the cells within the limbic system, this has led people to believe that this system is evolutionarily older than the cerebral cortex itself.

Fear/memory
