简介：
Overview
This protocol describes a unique experimental model of tic disorders by laying out the method for inducing motor tics in freely-behaving rats, either in a transient or chronic manner. The main advantage of this method is that it describes the only available model of tic expression, which is widely used to study Tourette syndrome and other tic disorders.

What are the advantages of this tic model?
This model is the only widely used method for studying tic disorders, providing unique insights into Tourette syndrome.
How are the tics induced in the rats?
Tics are induced through striatal cannula implantation and the application of GABA A antagonists.
What is the difference between acute and chronic models?
The acute model uses transient injections, while the chronic model employs prolonged infusions via mini-osmotic pumps.
Who demonstrates the procedure in the video?
The procedure is demonstrated by Esther Vinner, a graduate student, and Katya Belelovsky, the lab manager.
What is the significance of this research?
This research provides essential protocols for studying tic disorders, which can lead to better understanding and treatment options.
