Fig.6.

Time dependent changes in stimulation/background field potential counts and activated/resting-state CBF before and after cocaine administration (at t=0min). (a) forepaw activated SEP counts (NSEP) vs background field potential counts (nrest) showing that the stimulation to background neuronal activity ratio was increased after cocaine; (b) ΔCBFt/CBF0 showing that the stimulation to background cerebral blood flow ratio was decreased after cocaine.
