Abstract

Luminance of extended-duration adapting field was varied from zero to a level sufficient to reduce brightness of a 5 ms test stimulus to a level just above increment threshold. Increasing the luminance of surrounds or solid adapting fields resulted in increased reaction time. With the perceived-order method, reduction of latency with increasing surround luminance (temporal facilitation) was obtained with a visual comparison stimulus but not with an auditory comparison. It was concluded that perceived motion is a necessary condition for temporal facilitation. This study and earlier studies using moving test stimuli may be explained by a shift from sustained to transient units with increasing adapting luminance.

Ontogeny of a photic response in the retina and suprachiasmatic nucleus in the mouse.

The ontogeny of photic responsiveness in the retina and the suprachiasmatic nucleus (SCN) of C57BL/6J mouse was studied using the enhanced expression of the immediate early gene c-fos as a marker of neuronal activation. c-fos expression was assessed by immunocytochemical localisation of its protein product. Light induction of Fos-like protein in the retina and SCN occurred first at postnatal day four (PD 4). At this stage of development, some cells in the inner part of the neuroblastic layer and in the ganglion cell layer showed positive immunoreaction; the number of Fos-like positive cells increased with age until it reached adult levels by PD 15. Induction of Fos-like expression at PD 4 in the SCN mainly occurred in the ventrolateral region, the region that receives the greatest density of retinal innervation. These results indicate that retinal input can activate cells in the SCN even before eyelids open, and the SCN can be stimulated by photic inputs as early as day 4 after birth.

Calcium transients in the rhabdomeres of dark- and light-adapted fly photoreceptor cells.

The light response of fly photoreceptor cells is modulated by changes in free Ca(2+) concentration. Fly phototransduction and most processes regulating it take place in or very close to the rhabdomere. We therefore measured the kinetics and the absolute values of the free Ca(2+) concentration in the rhabdomere of fly photoreceptor cells in vivo by making use of the natural optics of the fly's eye. We show that Ca(2+) flowing into the rhabdomere after light stimulation of dark-adapted cells causes fast Ca(2+) transients that reach peak values higher than 200 microM in <20 msec. Approximately 500 msec later, the free Ca(2+) concentration has declined again to approximately 20 microM. The duration of the Ca(2+) transients becomes still shorter, and their size reduced, when the photoreceptor cell is light-adapted. This reduction in duration and size of the Ca(2+) transients is graded with the intensity of the adapting light. The kinetics and absolute values of the free calcium concentration found to occur in the rhabdomere are suitable to mediate the fast feedback signals known to act on the fly phototransduction cascade.

GABA(C) receptors control adaptive changes in a glycinergic inhibitory pathway in salamander retina.

We studied the role of GABA in adaptive changes in a lateral inhibitory system in the tiger salamander retina. In dark-adapted retinal slice preparations picrotoxin caused a slow enhancement of glycine-mediated IPSCs in ganglion cells. The enhancement of glycinergic IPSCs developed slowly over the course of 5-20 min, even though picrotoxin blocked both GABA(A) and GABA(C) receptors within a few seconds. The slow enhancement of glycinergic IPSCs by picrotoxin was much weaker in light-adapted preparations. The slow enhancement of glycinergic inhibitory inputs was not produced by bicuculline, indicating that it involved GABA(C) receptors. The responses of ganglion cells to direct application of glycine were not enhanced by picrotoxin, indicating that the enhancement was not caused by an action on glycine receptors. In dark-adapted eyecup preparations picrotoxin caused a slow enhancement of glycinergic IPSPs and transient lateral inhibition produced by a rotating windmill pattern, similar to the effect of light adaptation. The results suggest that the glycinergic inhibitory inputs are modulated by an unknown substance whose synthesis and/or release is inhibited in dark-adapted retinas by GABA acting at GABA(C) receptors.
