To localize the oral primary somatosensory cortex, we measured somatosensory-evoked fields for the lip, gingiva, and tongue in six healthy subjects. The latency of the first peak of the posterior-oriented current in the contralateral hemisphere was 50.9 +/- 8.3 ms for the gingiva, significantly shorter than those for the lip and tongue peaks. The equivalent(More)
Using parvalbumin (PV)-immunocytochemistry, we identified the human primary auditory field (PAF) for the first time. The first gyrus of the right Heschl was identified, and a serial perpendicular cut to the gyrus was made. PV-immunoreactive neuropils delineated four zones, as have been described in monkeys. Unlike with conventional staining, zone 1,(More)
The somatotopic organization of the human primary somatosensory (SI) area in the cerebral cortex has been intensively studied for the hand, lip, and tongue, but little is known about the gingiva. Penfield concluded that the gingival SI area was above the tongue area, as shown in his famous homunculus map. However, our recent study suggested that the lingual(More)
The developmental expression of arginine vasopressin (VP) and VP mRNA in human hypothalamus was studied using combined immunocytochemistry (ICC) for VP-neurophysin II and in situ hybridization (ISH) for VP mRNA. Routine formalin-fixed autopsy material was used from 22 cases ranging in age from 18 wk of gestation to 21 yr. VP-neurophysin II immunoreactive(More)
