Portable wireless transcranial ultrasound brain stimulation for freely behaving small animals

Conventional transcranial ultrasound stimulation (tUS) for animal studies utilize external bulky transducer systems, requiring the use of wires that limit the study to anesthetized or immobilized subjects. To facilitate behavioral studies with ultrasound, we designed a portable wireless tUS system that can provide acoustic stimulation on a freely behaving rat. Stimulation is given by a transducer attached on the rat skull that is driven by a circuit placed on the back of the rat. The whole system is controlled wirelessly via bluetooth.
