Fig. 6: Living retina stimulation of F-URSP.
From: Flexible ultrasound-induced retinal stimulating piezo-arrays for biomimetic visual prostheses
a Schematic diagram and photograph showing the ex vivo murine retina tissue and experimental setup for the retina stimulation using the F-URSP. The retina tissue was removed from the eye of an anesthetized mouse and stimulated using F-URSP. The inset shows the living retina placed under the stimulating electrodes of the F-URSP. Scale bar: 1 mm. b Measured acoustic pressure distribution of a “V”-shaped pattern emitted by a 2D array transducer through a hydrophone probe. The color bar indicates the normalized acoustic pressure. The maximum value is 0.45 MPa. c Calcium imaging of the living retina at stimulated levels. d Time course of calcium transients during stimulation. Source data are provided as a Source data file.
