Which of the following is not a forebrain structure? amygdala hippocampus pons thalamus

The correct answer is - amygdala.

The amygdala is not part of the forebrain structure, as it is out of it, and it is located just behind in it as two separate parts on each sides. The amygdala is consisted of two separate parts, with the shape of an almond, thus getting its name.

It is constructed as two almond-shaped cluster nuclei that are located medial and deep into the lobes of the brain, and it can only be found in the complex vertebrates.

The role of the amygdala is to process the decision-making, emotional responses, and the memory.
