High-magnification brightfield photomicrographs of anterogradely PHA-L– labeled fibers in case M-17-07. A: Fibers in the outer portion of the molecular layer of the dentate gyrus. The fibers have a substantial range of thicknesses but virtually all have varicosities (arrows) that are reminiscent of synaptic boutons. B: Fibers in stratum lacunosummoleculare of CA1. Again, fibers range from thick nonvaricose fibers, particularly in the superficial portion of the field, to thinner highly varicose fibers (arrows) in the deeper portion of the field. Scale bar = 10 μm in B (applies to A,B).
