Human brain produced and circulated. Underneath the cerebral cortex are several important structures, including the thalamus, the epithalamus, the pineal gland, the hypothalamus, the pituitary gland, and the subthalamus; the limbic structures, including the amygdala and the hippocampus; the claustrum, the various nuclei of the basal ganglia; the basal forebrain structures, and the three circumventricular organs. The cells of the brain include neurons and supportive glial cells. There are more than 86 billion neurons in the brain, and a more or less equal number of other cells. Brain activity is made possible by the interconnections of neurons and their release of neurotransmitters
Ten percent of the brain myth the human brain is capable of exhibiting psychic powers and can be trained to perform psychokinesis and extra-sensory perception. There is no scientifically verified body of evidence supporting the existence of such powers. In 1980, Roger Lewin published an article in "Science", "Is Your Brain Really Necessary?", about studies by John Lorber on cerebral cortex losses. He reports the case of a Sheffield University student who had a measured IQ of 126 and passed a Mathematics Degree but who had hardly any discernible brain matter at all since his cortex was extremely reduced by hydrocephalus. The article led to the
