Neuron Neuron A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals. These signals between neurons occur via specialized connections called synapses. Neurons can connect to each other to form neural pathways, and neural circuits. Neurons are the primary components of the central nervous system, which includes the brain and spinal cord, and of the peripheral nervous system, which comprises the autonomic nervous system and the somatic nervous system. There are many types of specialized neurons. Sensory neurons respond to one particular type
Electrical brain stimulation motor and sensory territories). EBS remains inextricably entwined with the work of Dr. Robert Galbraith Heath, Dr. Jose Delgado and Dr. Wilder Penfield. It's of interest that during cerebral localization studies, neurosurgeon Penfield could not elicit emotional reactions in humans, either by observing spontaneous epilepsy or by electrically stimulating the surface of the cerebral cortex. Neurophysiologist Dr. Jose Delgado noted a few exceptions to this rule. In contrast, EBS, via deeply implanted electrodes in localized areas of the brain (deep brain stimulation; DBS), elicited both pleasurable and aversive responses in laboratory animals and man as previously described. EBS could elicit
