Figure 2: Reconstruction of three-dimensional orientation maps.
From: Mixed functional microarchitectures for orientation selectivity in the mouse primary visual cortex
(a,c,d) Orientation maps reconstructed for layer 2/3 (a), layer 4 (c) and layer 5 (d). Calcium signal changes are calculated for all the pixels, and every pixel is coloured according to the response to the orientation stimuli (hue: preferred orientation; lightness: response magnitude; saturation: gOSI). The upper panels show a three-dimensional map. The lower panels show y–z side sections (a,c,d). Vertically aligned cell rows are indicated by arrows and marked by numbers (1–6) or white asterisks (*). (b) Calcium transients of cells shown in a (1–6) in response to the orientation stimuli. Grey shaded: stimulation periods; white: blank periods. The angle of orientation presented during each stimulation period is illustrated at the bottom. Scale bars, 30 μm.
