This protocol describes a unique experimental model of tic disorders by laying out the method for inducing motor tics in a freely-behaving rat, either in a transient or chronic manner. The main advantage of this method is that it describes the onl

We present protocols for generating acute and chronic experimental models of tic expression in freely behaving rats. The models are based on striatal cannula implantation and subsequent GABAA antagonist application. The acute model uses transient injections whereas the chronic model utilizes prolonged infusions via a subcutaneous implanted mini-osmotic pump.
