The subventricular zone (SVZ) of the lateral ventricle remains mitotically active in the adult mammalian central nervous system (CNS). Recent studies have suggested that this region may contain neuronal precursors (neural stem cells) in adult rodents. A variety of neuronal and glial markers as well as three extracellular matrix (ECM) markers were examined(More)
Transient neurophysiological changes in CA3 neurons and dentate granule cells after severe forebrain ischemia in vivo. J. Neurophysiol. 80: 2860-2869, 1998. The spontaneous activities, evoked synaptic responses, and membrane properties of CA3 pyramidal neurons and dentate granule cells in rat hippocampus were compared before ischemia and </=7 days after(More)
It has been argued that labels play a special role in cognitive development: hearing the same label associated with different entities facilitates categorization by directing infants' attention to commonalities. The current study assessed 8-month-olds' attention to commonalities and processing of visual input more generally when visual stimuli were(More)
The electrophysiological responses of CA3 pyramidal neurons and dentate granule (DG) cells in rat hippocampus were studied after transient forebrain ischemia using intracellular recording and staining techniques in vivo. Approximately 5 min of ischemic depolarization was induced using 4-vessel occlusion method. The spike threshold and rheobase of CA3(More)
The current study investigated comprehension of object labels in young children. Eight-and 14-month olds were presented with pairs of pictures (e.g., dog and ball) to establish infants' initial looking preferences and then children heard a linguistic label (e.g., dog). Only 14-month-olds reliably increased looking to the referents after hearing the labels(More)
