The effects of cocaine by two routes of administration were studied on the resting, awake human EEG during a 2 min sequential subtraction task. Fifty subjects were given 1 of 3 intravenous cocaine doses (0.2, 0.4 and 0.6 mg/kg). Thirty-three subjects received 1 of 3 oral doses of cocaine (2, 3 and 4 mg/kg). The EEG was analyzed as spectral power for delta, theta, alpha and beta bands. At each dose for both routes of administration, cocaine increased beta power. The increase was observed at the 5 min post-drug test session for the subjects given intravenous cocaine and at both 45 and 75 min test sessions for subjects given oral doses. In addition, a decrease in delta power was found at the 5 min test for the intravenous group and theta power was decreased at the 45 min test session. The increase in beta power was correlated with the area under the cocaine plasma versus time curve, but not with the cardiovascular effects of cocaine. The increased beta activity observed with cocaine may be a consequence of the direct stimulation of a central noradrenergic arousal system.
