in vivo calcium imaging of auditory cortical neurons. a AAV9-CaMKII-GCaMP6f expression and prism probe position in the auditory cortex. GCaMP6f: Green; DAPI: Blue. Scale bar: 1 mm. b Coronal section from a representative mouse brain showing the prism probe tract with its imaged side facing the GCaMP6f-expressing cells. Solid line, prism probe tract; dashed line, focal plane. Scale bar: 200 μm. c & d The contours of detected neurons superimposed on the image of a representative field of view. Scale bars: 100 μm (c), 50 μm (d). e. Fluorescence traces of the example region of interest (colored in c & d). Gray shading, sound presentation period
