Fig. 3: Spatially confined acoustic wave and neural stimulation induced by FOC.
From: Optoacoustic brain stimulation at submillimeter spatial precision
a FOC wavefront reconstruction by the transducer array. Note only part of the wavefront is reconstructed due to the limited receptive angle of the transducer array. b Acoustic intensity attenuates significantly as the distance to the FOC increases. c, d Spatial distribution of maximum neuronal calcium response induced by 200 ms FOC stimulation. Dashed line: placement of FOC. e Sorted calcium traces of neurons by the distance from the cell to the FOC. Green arrow: stimulation onset. Source data are provided as a Source Data file.
