Which structure of the Limbic system is mostly responsible for controlling the emotional behaviour of fear?

Correct option is A

The Amygdala is the structure of the Limbic system primarily responsible for controlling the emotional behavior of fear.

Information Booster:

1. Key Functions:
The amygdala processes emotions, particularly fear and aggression, and plays a role in emotional memory, threat detection, and emotional learning. It is involved in the fight-or-flight response, and helps regulate emotional reactions.

2. Features:
Located in the temporal lobe near the hippocampus, the amygdala has two almond-shaped structures, one in each hemisphere. It is part of the limbic system and has key nuclei (e.g., lateral, central) that process different aspects of emotions.

3. Location:
The amygdala is found in the medial temporal lobe, in front of the hippocampus. It is bilateral, with one in each hemisphere of the brain.

Additional Information:

(b) Hippocampus: The hippocampus is primarily involved in memory formation and spatial navigation.
-The hippocampus is located in the medial temporal lobe, underneath the cerebral cortex, and is part of the limbic system. It lies near the amygdala and is involved in memory and emotional processing.

(c) Cingulate gyrus: The cingulate gyrus plays a role in emotional regulation, pain processing, and decision-making
-The cingulate gyrus is located in the medial part of the brain, above the corpus callosum, and forms part of the limbic system. It wraps around the brainstem, connecting the frontal and parietal lobes.

(d) Mammillary bodies: The mammillary bodies are involved in memory processing
-The mammillary bodies are small, round structures located at the base of the brain, part of the hypothalamus. They are positioned just behind the pituitary gland and below the thalamus, in the diencephalon region of the brain.
