Mathematical Model of the Habituation Process as a Learning Basic Phenomena in PC-12 Cells.
Valdivia, Adolfo Obaya
Learning processes have been investigated for regularities of the changes in the strength of a reflex that result from manipulations of several parameters of a stimulus. Most of this work has been carried out in the tradition of associative theory. One consequence of this emphasis was that for a long time several phenomena that can be characterized properly as learning were ignored. This group includes habituation, sensitization, pattern recognition and acquisition of motor skills. However, now it is common to find references in the literature to behavioral changes that are not the result of some associative process. Among the nonassociative phenomena, habituation has received the most attention in the contemporaneous study of learning. Habituation is defined as a decrement in the response that results from its repeated elicitation. If we include as learning all those behavioral changes that are a product of experience, habituation would be one of the most elementary forms of learning. Additionally, habituation is observed in a large variety of species and organisms like PC-12 cells. Since they are a model of the neuronal system, the explanation of the behavioral changes that take place during habituation can become one of the building blocks of a more general theory of behavioral plasticity. This work describes the principal characteristics of the process of habituation that permit a definition of habituation as a basic process of learning and illustrates some methodological problems faced in the study of its parameters. A mathematical model that explains behavioral changes observed in PC-12 cells in situations of repetitive stimulation is proposed. (Contains 26 references, 11 figures, and 5 tables.) (Author/NB)
