[The relationship between the frequency of self-stimulation and parameters of the stimulus].
The dependence of self-stimulation frequency on stimulation parameters (current intensity, stimulation frequency, pulse duration, duration of pulse bursts) was studied in fifteen rats with monopolar electrodes implanted in the lateral hypothalamus, using rectangular current pulses for brain stimulation. All the experiments revealed qualitatively similar response surfaces to the combined change of stimulation frequency and pulse duration Self-stimulation frequency is connected in a non-linear way with the "specific charge" per unit of time, and in an approximately linear way, with the duration of the pulse burst. Regression equations are determined which precisely enough described the kind of response surface (R =0.7 to 0.95).
