Data in bold print are mean percentage input to the target regions from the origins based on total normalized numbers of labeled cells arising from retrograde tracer injections. Data for layers are percentages of labeled cells for the particular region. Numbers of cells labeled in each region can be calculated from the estimated total number of labeled cells. Data are means±SEM.
