 The author next turns his attention to the central nervous system.He lists the prime functions of the brain in mammals as control and coordination of neuromuscular activity, to set into action innate programs of action in response to stimuli, to integrate sensory inputs, to register, group, and associate significant events, and to represent and simulate.Monod makes the point that behavior cannot be strictly separated as learned or innate since elements are acquired through experience according to an innate program and "the program's structure initiates and guides early learning, which will follow a certain pre-established pattern defined by the species' genetic patrimony" (Monod, 153).
