  1. The system consists of a single element focused ultrasound transducer, a power amplifier and a function generator. The function generator produces a pulsed sinusoidal waveform. The pulse center frequency was 1.0 MHz; the pulse repetition period was 6 s; the pulse duration was 1 s. The duty cycle is the fraction of time that the ultrasound stimulus is active within each pulse repetition period, which was 16.7% in our study. The total stimulation time was 12 min or 6 min. The different ultrasound pressures were set as 0.1 MPa, 0.35 MPa, 0.473 MPa. The corresponding voltage was 94.7 mV, 409.3 mV and 1000 mV, respectively
