Abstract
The theta-rythm of the rat's hippocampus in paradoxical phase of sleep and in orientational behavior is investigated by estimating the attra ctor's dimension. It is shown that the theta-rythm of the hippocampus consists of a regular component and an irregular one of high dimension which relation is in the wide variation depending on the state of the animal. The frequency characteristics of both components are revealed as well as the mechanisms of their forming. Some hypothesis that conc ern their biological nature are suggested.
