TIP39 neurons in the subparafascicular area of the rat posterior thalamus. A: TIP39-ir neurons (green) are shown in the PVG in coronal sections labeled with a fluorescent Nissl dye (red) at antero-posterior (AP) coordinates -4.2, -4.4, and -4.6 mm from the bregma level. B: The position of the PVG is shown in a drawing of a sagittal section of the rat brain at 0.4 mm lateral from the midline (Paxinos and Watson, 1998). C: A photomicrograph of a sagittal section corresponding to panel B shows the location of TIP39-ir neurons in the PVG. D: TIP39-ir neurons and fibers are shown in a horizontal section 6.8 mm ventral to the surface of the brain. The large density of TIP39-ir neurons in the PVG is in contrast to the scattered TIP39-ir neurons in the PIL while TIP39-ir fibers connect the 2 regions of TIP39 expression.
