The synapse is the site of specific interaction between nerve ceils. It results from a complex
series of developmental events, during which axonal processes grow to specific regions …

The development of synapses in the visual cortex (VC) and superior colliculus (SC) of the
rabbit has been examined with the electron microscope. In both areas, the number of …

The upper layers of the superior colliculus of the adult rat have a set of characteristic and
quantitatively stable synaptic features. The changes in distribution of these features have …

Three periods of synaptic development have been previously 22 demonstrated in the
superior colliculus of the rat. In this study of ratios of certain synaptic patterns, eyelid closure …

Fine structural and quantitative aspects of the synaptic organization of the superior colliculus
of the rabbit were studied. The synaptic density, the frequency of the distinct types of …

The superior colliculus is organized into a superficial zone which is directly connected with
other parts of the visual system and a deep zone which is not directly connected with other …

The spatial distributions of retinal and area 17 synapses in the zonal, superficial gray, and
upper optic layers of the cat superior colliculus have been examined quantitatively. The …

An electron microscopic study has been undertaken of the upper layers of the superior
colliculus, into which run fibers from the retina and visual cortex. Study of the normal …

While the synaptic patterns studied with the electron microscope in the upper layers of the
superior colliculus of the monkey are basically similar to those described for the rat, there …

Synapses have been counted by electron microscopy and neurones by light microscopy
through the depth of the visual cortex in a series of cats from 37 days gestation to adulthood …
