Table 1.

Dorsal-ventral distribution of retrogradely labeled cells on coronal section at the injection site. SL: single-labeled cells, WAHG+ only; DL: double-labeled cells, co-localization of WAHG and PV. Counts are the total of three cases, and are provided for each cortical layer. % = (DLs /Total labeled cells in each bin) * 100.
