Le cerveau à tous les niveaux. Chapter 8. Neurons, Synapses, Action Potentials, and Neurotransmission - The Mind Project. Return to MODULE PAGE Neurons, Synapses, Action Potentials, and Neurotransmission Robert Stufflebeam: Author, Artist & Animator Functions of Neurons The central nervous system [CNS] is composed entirely of two kinds of specialized cells: neurons and glia. Hence, every information processing system in the CNS is composed of neurons and glia; so too are the networks that compose the systems (and the maps).
Clearly, without these two types of cells, the CNS would not be able to do what it does (which is everything having to do with our minds and how we move our bodies). Neurons are the basic information processing structures in the CNS. While we are considering numbers, it is worth noting that there are as many as 50 times more glia than neurons in our CNS! Because our main interest lies in exploring how information processing occurs in the brain, we are going to ignore glia.
