a Calcium responses from a single neuron during ultrasound stimulation before, during and after treatment with the sodium channels blocker tetrodotoxin (TTX). b Quantification of area under the curve before, during and after TTX treatment (n = 3 independent experiments, one-way ANOVA p = 0.0004, Tukey’s post comparison (control vs. TTX)). c Diagram of the Ace2N voltage indicator genetic construct and representative fluorescence image of neurons transfected with this construct. d Voltage responses to ultrasound. (n = 4 independent experiments). e Voltage responses of neurons in calcium-free media (n = 2 independent experiments). Mean trace is solid and SEM is shaded. Bar graph values represent mean ± SEM.
