Research Abstract |
The basal ganglia is supposed to important for motor control. We have applied ‘ optogenetics (the combination of genetics and optics to control cellular excitability)’ to mice to clarify the mechanism of motor control in the pathway of the basal ganglia. Specific excitation in striatal projection neurons in the hemisphere has induced phasic inhibition in the output signal from the basal ganglia, and has induced rotational behavior. These data suggest that phasic response in the output signal is important to regulate motor activity.
