A computer processes and relays the electrodes’ signal to an ultrasound machine over the rat’s head, which delivers low-energy ultrasound pulses into the its brain, stimulating its motor cortex–the area that controls its movements. The pulses are aimed at area the size of a grain of rice that controls the rat’s tail. It starts to wag.
