[The dynamics of the integral parameters of orienting-exploratory and searching behaviors in rats]

Multiple five-day testing of rats in the open field and elevated plus-maze revealed a regressive dynamics of the integral characteristics of the exploratory behavior. The integral quantitative indices of searching activity in Henderson's test of extrapolation deliverance (modified by N. A. Bondarenko) and in active shock avoidance in N. R. Grigor'ev's problem box, on the contrary, displayed a progressive dynamics, like quantitative characteristics of cognitive activity. We established the differences between the determinants and control mechanisms of exploratory behavior and searching activity. This allowed us to differentiate these forms of behavior as different functional states.
