<start_of_turn>model
There are 100 billion neurons in the brain. A neuron, or nerve cell, is an excitable cell constituting the basic functional unit of the nervous system. Neurons ensure the transmission of a bioelectric signal called nerve impulses. They have two physiological properties: excitability, i.e. the ability to respond to stimulation and convert these into nerve impulses, and conductivity, i.e. the ability to transmit impulses .<end_of_turn><eos>
