We investigated the influence of modulating NO synthesis on oscillatory components of ON and OFF evoked field potentials in developing rat superior colliculus. Nitric oxide (NO) is involved in neuronal transmission by adjusting neurotransmitter relea

The present investigation is aimed at characterizing the development of ON and OFF visually evoked responses in the rat superior colliculus from postnatal day 13 (P13) to postnatal day 25. Depth profiles of field potentials reveal that ON and OFF lon

During the first 10 days after birth in the rat there are a succession of major developmental stages in the retinotectal pathway. During most of this time, the only recordable event in the superior colliculus is spontaneous activity. We studied and c

Electrophysiological activity in the neonatal rat superior colliculus was recorded to measure neuronal and synaptic activity, and, therefore, functional development. Neonatal rat pups were studied from five days to two weeks of age. The earliest acti

Nitric oxide (NO) is involved in neuronal transmission by modulating neurotransmitter release in adults and in stabilizing synaptic connections in developing brains. We investigated the influence of downregulation of NO synthesis on oscillatory compo

Retinal projections in rats were studied using anterograde horseradish peroxidase (HRP) tracing and electron microscopic (EM) degeneration. HRP-labeled axons were observed to leave the optic tract in the vicinity of the lateral geniculate nucleus and

Wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP) was injected intraocularly in monkeys and rats. All known primary visual pathways were labeled and, in addition, ocular dominance columns in visual cortex were labeled in monkey, an

The tracer, wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP), was used as a transneuronal marker in the macaque monkey to study retino-geniculo-striate pathway terminals in area 17. Concomitantly, we stained matching sections for

Horseradish peroxidase (HRP) and wheat germ agglutinin conjugated to HRP (WGA-HRP) were used as anterograde tracers to study the macaque monkey retinofugal pathways. Labeled axons were mapped beyond the lateral geniculate nucleus to the inferior (PI)

Summary Visual pathways were studied using horseradish peroxidase (HRP) as an anterograde tracer after intraocular injections in rats and monkeys. Retinal axons continue caudally from the stratum opticum of the contralateral superior colliculus at th
