Y1R+ neurons can express VIP and/or CCK. High-magnification confocal images of a coronal IC section showing VIP (magenta), CCK (yellow), and Npy1r (white) expression. Arrows indicate examples of cells that are VIP+CCK+Y1R− (blue arrows); VIP−CCK+Y1R+ (white arrows); and VIP+CCK+Y1R+ (magenta arrows). Dotted circles represent individual neurons. Scale bar, 5 μm.
