The cellular composition of the primate claustrum was analyzed using serially sectioned Golgi impregnated neurons. The tissue used in this study was embedded in a soft resin mixture and cut with 25 mm long glass knives. The resin embedding allowed the sections to be cut serially at a thickness of only 3 μm. A camera lucida was employed for drawing the(More)
Experimental light and electron microscopic studies were carried out to determine the length of parallel fibers in the cat cerebellar cortex. Using a fine surgical knife, vermal and hemispheral folia were cut perpendicular to their long axis. The animals were sacrificed 1–10 days after the operation. Sections of the transected folia were then stained with a(More)
We used anemone toxin II (ATX II) to study how a selective enhancement of persistent Na+ current (INaP) would affect the excitability of CA1 pyramidal neurons in the hippocampal slice. In whole-cell recordings from CA1 cell somata, local application of ATX II (10 microM) into the stratum pyramidale invariably depolarized the neurons and produced sustained(More)
the cerebellar cortex of the pond turtle (Pseudemys scripta elegans) was analyzed with histochemical methods for the enzyme acetylcholinesterase (AChE) in the light and the electron microscope. The glomeruli in the granular layer were moderately AChE positive throughout the cerebellum. The molecular layer, however, showed a peculiar pattern of AChE(More)
Young and adult cats were operated upon and a number of the vermal cerebellar folia were either transected with a vertical incision or isolated by a horizontal cut. In the proximity of the lesion, Purkinje cell bodies and their dendritic trees became stainable with the Fink-Heimer method. Electron microscopy of the silver stained sections show that the(More)
Cytodifferentiation and synaptogenesis in the neostriatum (caudate nucleus and putamen) were analyzed by the Golgi impregnation method and electron microscopy in 14 fetuses and 8 postnatal rhesus monkeys. During the second fetal month the neostriatum consists primarily of simple, mostly bipolar, immature cells and a small number of undefined profiles ending(More)
