Suppression of EEG visual-evoked potentials in rats through neuromodulatory focused ultrasound
We investigated the use of pulsed low-intensity focused ultrasound (FUS) to suppress the
visual neural response induced by light stimulation in rodents. FUS was administered
transcranially to the rat visual cortex using different acoustic intensities and pulsing duty
cycles. The visual-evoked potentials (VEPs) generated by an external strobe light
stimulation were measured three times before, once during, and five times after the
sonication. The VEP magnitude was suppressed during the sonication using a 5% duty …
