Couple with Glass Head Revealing Limbic System



Video Topic : Visualization beginning with two orange glass heads (one man and one woman) with the eyes, optic nerves, and brains showing. The camera rotates to the right and over the heads while the brains fade out. While this happens, the glass heads and outlines of the brains turn white. Once on the other side of the female's head, there is a close up of the limbic system and spinal cord. The camera zooms out while moving to the male head and then zooms in on the paraventricular nucleus of the hypothalamus.

Limbic System

A set of forebrain structures common to all mammals that is defined functionally and anatomically. It is implicated in the higher integration of visceral, olfactory, and somatic information as well as homeostatic responses including fundamental survival behaviors (feeding, mating, emotion). For most authors, it includes the AMYGDALA; EPITHALAMUS; GYRUS CINGULI; hippocampal formation (see HIPPOCAMPUS); HYPOTHALAMUS; PARAHIPPOCAMPAL GYRUS; SEPTAL NUCLEI; anterior nuclear group of thalamus, and portions of the basal ganglia.

The limbic system, which contains the brain's reward circuit. It links together a number of brain structures that control and regulate our ability to feel pleasure. Feeling pleasure motivates us to repeat behaviors that are critical to our existence. The limbic system is activated by healthy, life-sustaining activities such as eating and socializing-but it is also activated by drugs of abuse. In addition, the limbic system is responsible for our perception of other emotions, both positive and negative, which explains the mood-altering properties of many drugs.
