Differential recruitment of V3 INs in running and swimming behaviors. A, Confocal image of dorsal V3 neurons (red) expressing c-Fos protein (green) at rest or after running and swimming. B, c-Fos-positive V3 INs are mapped onto cross sections of lumbar cords from control (Bi), running (Bii), and swimming (Biii) mice. Cells are divided into ventral (gray), intermediate (black), and dorsal (white). C, Histogram showing proportion of c-Fos-positive V3 INs relative to the total number V3 INs at different positions. *p < 0.01.
