| Abstract: | The influence of diazepam (1 and 5 mg/kg, i. p.) and buspirone (5 and 10 mg/kg) on the Fourier's spectral EEG power of sensomotor cortex and a conflict behavior in freely moving rats were studied. Diazepam (1 mg/kg) and buspirone (5 mg/kg) produced slowing of EEG theta-activity. Large doses of diazepam and buspirone produced different and multiple EEG effects. To 15-1788 (10 mg/kg) completely antagonized all the effects of diazepam (5 mg/kg). The authors discuss possible mutual relations between the influence on EEG and anxiolytic effect of these tranquilizers. |
