Respuesta :
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.
The amygdala is not a part of the forebrain structure.
Further Explanation:
The biggest area of the brain is occupied by the forebrain. The thalamus, the limbic system, the pineal gland and the hypothalamus are the parts of the forebrain. The body's temperature, eating, sleeping, reproductive functions are all controlled by the forebrain.
A collection of nuclei inside temporal lobe is known as the amygdala. Each hemisphere contains one amygdalae. The term is derived from a Latin word which means “almond”.
A tiny, arched formation in the brain which plays a major part in the limbic system is known as hippocampus. New memories formation, learning and emotions are all the roles of hippocampus.
A tiny structure in the brain that is present just on the brain stem in the middle of the midbrain and the cerebral cortex is known as the thalamus.
The relay of sensory and motor signals to the cerebralcortex is the major function of thalamus. The sleep is also regulated by the thalamus. All these parts mentioned in the question are the portions of the forebrain except for the amygdala. The amygdala is not a part of forebrain. Rather, it lies outside the forebrain.
