THE INDIRECT VERIFICATION OF MINIMAL 2-GENERATOR MODEL OF HOMEOSTATICDRINKING BY COMPLEXITY EXAMINATION

In the course of previous examinations, it has been suggested that min imally two lick pattern generators have to take part in the formation of temporal patterns of homeostatic drinking. The drinking pattern of five rats was investigated, subsequently analysed and compared to simu lated data. As the interaction of the two generators changes by the pr ogress of satiation, the dynamics of drinking have to change too. In t his experiment we demonstrated this nonlinear dynamical change by the examination of algorithmic complexity which reflects the nature of mot ivational changes and that the proportion of the change of complexity is in harmony with our model of homeostatic drinking.
