Sensitivity Profile for Orientation Selectivity in the Visual Cortex of Goggle-Reared Mice
Figure 1
Cortical activation patterns and orientation distributions.
(A) Single-orientation maps of an NR mouse and a mouse GR from P21 to P28, which were reconstructed from intrinsic signal optical imaging conducted at P29 and P28, respectively. The darkness indicates the strength of intrinsic signals evoked by oriented grating stimuli. The dotted rectangles show the region of interest. R: rostral, L: lateral. (B) Orientation distributions obtained from the single-orientation maps shown in (A). The ordinate indicates the relative size of activation areas eliciting stimulus-related responses stronger than 2SD for each stimulus orientation. (C) Group-averaged orientation distributions for NR (n = 45) and GR (n = 44) groups of juvenile mice. Error bars indicate SE (standard error). All scale bars indicate 1 mm.
