[Measurement of spontaneous motor activity by using the vibrator response method in rats].
To investigate the usefulness of spontaneous motor activity (SMA) measurement using the vibrator response method, the acute effects of drugs on SMA were observed in Sprague-Dawley male rats. There were no significant differences between four devices. Methamphetamine (0.3-1 mg/kg, i.p.) and 1-2 mg/kg (s.c.) of apomorphine increased the SMA, but 0.05-0.2 mg/kg (s.c.) of apomorphine decreased the SMA. Apomorphine at 1-2 mg/kg (s.c.) significantly increased the SMA when the vibrator response method was used as compared with the Animex method. These results suggest that the vibrator response apparatus is useful for the measurement of SMA in rats.
