Hypothalamic autostimulation in rats at low frequencies of stimulation on the basis of locomotion]

A study was made of the hypothalamic autostimulation of rats with the impulse stimulation frequency of from 30 to 7 cycles/sec. The animals' brain was stimulated in Skinner's chamber and on the basis of locomotion. The duration of a series of impulses established by the animal on the basis of locomotion grew with reduction of the frequency of stimulation impulses. The pauses between the series of impulses and the duration of the series were also prolonged with a voltage reduction. With the help of stimulation frequency of 7 cycles it was possible to choose such a current that the sum of the total duration of pauses lay within 0 divided by 10% of the total experimental time. The duration of individual pauses was less than 0.5 sec.
