The indirect verification of minimal two-generator model of homeostatic drinking by complexity examination

In the course of previous examinations, it has been suggested that minimally 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 simulated data. As the interaction of the two generators changes by the progress of satiation, the dynamics of drinking have to change too. In this experiment we demonstrated this nonlinear dynamical change by the examination of algorithmic complexity which reflects the nature of motivational changes and that the proportion of the change of complexity is in harmony with our model of homeostatic drinking.
