REINFORCEMENT CONCEPT IN INVESTIGATIONS O N SIMPLE NERVOUS SYSTEMS

Analysis of applicability of the reinforcement concept to the learning studies in invertebrate systems is performed basing on literature and own data. It is suggested that reinforcement can be regarded not as a n independent phenomenon, but as a state of the nervous system which p recedes a long-term changes of behavior. Such consideration of reinfor cement allows to use this concept in studies of plasticity and learnin g in simple nervous systems, investigate neurochemical mechanisms of r einforcement.
