Limbic system

The Limbic system is the part of the nervous system that allows humans to form memories and emotions. The first structure in the Limbic system is a small part below the thalamus, between two optic nerves, and above the pituitary gland. This part is known as the Hypothalamus; and it regulates the autonomic nervous system. Furthermore, the Hypothalamus controls how humans perceive different levels of certain behaviors or feelings inside the body. In other words, the Hypothalamus creates a homeostasis environment throughout the brain. The Hypothalamus sends these messages either through the autonomic nervous system or the pituitary gland. Another structure in the limbic system is the hippocampus. The Hippocampus converts short-term memories into long-term memories. It looks like “two ‘horns’ that curve back from the amygdala.” There are two amygdalas, almond-shaped masses of neurons, which control animals’ abilities to respond with fear and anger. For instance, when it is present and electrically charged animals will become aggressive.
