Fig. 12.     Rostro-caudal series of schematic coronal sections depicting the locations of juxtacellularly labeled non-cholinergic basal forebrain neurons that were tested for responses after substantia nigra (SN) or locus coeruleus (LC) stimulation using 2 µA. Cells # 4-8 responded both to SN and LC stimulation, while cells # 1-3 responded only to SN stimulation. Cell #9 did not respond to either stimulation.
