Thalamus, Hypothalamus, Hippocampus, Amygdala
Thalamus
The thalamus is a large , dual lobed mass of grey matter calls that are located at the top brain stem and is superior to the hypothalamus. Sometimes they are interconnected with the massa intermedia.
It sends information received from the different regions of the brain to the cerebral cortex.
iHypothalamus
The general functions of the hypothalamus are extremely important to the body, such as:
> pituitary gland regualtion
> feeding reflexes
> Hydration
> Water preservation
> testicular function
> metabolism
> Blood pressure regulation thirst
> Thirst
> Heart rate
> Sleep cycle
> Mood and behavioral functions

The hypothalamuc is located below the thalamus and posterior to the optic chiasma. It links the nervous system to the endocrince system by the pituitary glands.
Hippocampus
The Hippocampus is aprt of the forebrain that is located in the medial temporal lobe. It belongs to the limbic system. The hippocampus is mainly involved in memory, learning, and emotion.

Amygdala
The Amygdala are almond-shaped groups of neurons located in the medial temporal lobe. The Amygdala is involved in arousal, hormonal secretion, emotional responses, and controls the autonomic functions that are associated with fear.
