FIGURE 5.

Region-specific cortical projection to MOp and MOs. (A) Coronal sections show inputs to the motor cortex from different cortical regions. The green signals indicate the neurons projecting to the Mop, while the red signals indicate the neurons projecting to the MOs. Scale bar = 1 mm. (B) Three-dimensional reconstruction of cortical areas. A dot denotes one neuron projecting to the MOp (green) or MOs (red). (C) Schematic diagram for input areas projecting to subregions of the MC. The green and red circles represent injection site positions. Green areas indicate regions mainly projecting to the Mop, while red areas indicate regions mainly projecting to the MOs; yellow areas indicate regions projecting to both the MOp and MOs. Scale bar = 1 mm.
