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
In the Name of the Brother Viktor accepts the offer. Gerhardt finds Viktor digging up a body from a graveyard to use for his experiments. They are interrupted by a guard, who fatally shoots Gerhardt. Viktor attempts to revive Gerhardt in the laboratory, but the procedure burns his heart into charcoal. Alphonse discovers what has happened and disowns Viktor. Rumplestiltskin appears again and offers Viktor a magical heart in exchange for "putting on a show" for his "friend," Regina. After receiving the heart, Viktor successfully brings Gerhardt back to life. Alphonse is initially pleased, but becomes dismayed when he discovers Gerhardt is now an animalistic "monster."
