Amantadine modulates action-specific neural ensembles in hypokinetic and hyperkinetic conditions

Gaurav Chattree, Radosław Chrapkiewicz, Yanping Zhang, Jane Li, Fatih Dinç, Mark J. Schnitzer

The paper investigates how amantadine affects neural ensembles in hypokinetic and hyperkinetic conditions, finding it modulates action-specific ensembles rather than rebalancing pathway activity.
