Research of influence of low-frequency rhythmic electro-stimulation of subcrustal structures of rabbit brain on its ability to ultrasonic vocalization
Abstract
In work on the basis of experimental research, a comparative analysis of ultrasonic vocalizations of rabbits in a state of rest and during exposure to low-frequency rhythmic electrical stimulation (electric sleep) was carried out. The rest characterized typical two-peak shape of the ultrasonic signal: first peak of USV with greater power spectral density occurs in the frequency range of 20-25 kHz, while the second peak - in the range of 33-38 kHz. In the state of the ability to generate rabbit`s ultrasound electric sleep stored as ultrasonic waveform is similar to that of the rest. Low-frequency repetitive stimulation leads to a shift of the first peak of ultrasonic vocalizations in frequency and a slight decrease of the power spectral density of the second peak.
