Although molecular gradients have long been postulated to play a role in the development of topographic projections in the nervous system, relatively little is known about how axons evaluate gradients. Do growth cones respond to concentration or to slope? Do they react suddenly or gradually? Is ther

β¦ Synopsis
The finding of Adrian and Matthews ( '27), that a rhythmic discharge in the optic nerve can be recorded when no such rhythm is present in the retinal action current evinces the fact that the activity of the ganglion cell axons was not recorded in their retinograms. When the discharge of the ganglion cell axons is rhythmic it should be easily recognized in the retinogram, if it were recorded, as a series of short ripples added

Retinal ganglion cells (RGCs) in rats were retrogradely labeled with the fluorescent tracer Fluorogold (FG) and subjected to GAP-43 and c-JUN immunocytochemistry to identify those RGCs that are capable of regenerating an axon. After optic nerve section (ONS) and simultaneous application of FG to the
Inhibition of incorrect axonal outgrowth has been shown to be a crucial guidance mechanism during the development of the nervous system. Within the visual system of chick and rat, extension of retinal ganglion cell axons is essentially restricted to distinct layers of the retina and distinct brain r
