Figure 1: Latency of fall of experimental animals expressed in seconds. Veh; Control, - dopamine-2 receptors; Haloperidol-treated, +gamma aminobutyric acid; Diazepam treated, - dopamine-2 + gamma aminobutyric acid; haloperidol and diazepam treated. The graph shows that all treated group is significantly lower than the control P < 0.05. This shows that activating gamma aminobutyric acid nergic system does not alleviate motor coordination disorder experienced in Parkinsonism
