Functional Ultrasound Signals Reflect Modulation of Local Spiking

(A) Schematic of spike recordings with a multielectrode probe positioned in the primary visual cortex (left) or in the amygdala (right) during visual motion eliciting the optokinetic reflex. See also Figure S5.

(B) Standardized spike rate for all neurons recorded in each region (n = 3 mice). Black thick line, presentation of drifting gratings. Gray arrows, axis of visual motion.

(C) Spike rate averaged across all neurons with significant responses in the primary visual cortex (red) and amygdala (blue). Thick line, mean; widths of colored bands, 2 × SD.
