Serotonergic and serotonin-accumulating neurons in the goldfish retina.
Autoradiography of goldfish retinas incubated in micromolar levels of 3H-serotonin displayed 3 kinds of labeled somas in the inner nuclear layer: S1 amacrine cells with heavy labeling, large somas, and a sparse distribution (approximately 93/mm2); S2 amacrine cells with moderate labeling, smaller somas, and a denser distribution (approximately 500/mm2); and a subset of bipolar cells with light ...
متن کاملMorphological identification of serotonin-accumulating neurons in the living retina.
Neurons that accumulate the transmitter serotonin have been identified in the living retina by being labeled with 5,7-dihydroxytryptamine (5,7-HT), an autofluorescent serotonin analog. Iontophoretic injection of Lucifer yellow into the labeled cells under microscopic control revealed that the serotonin-accumulating neurons in rabbit retina constitute two morphological types of amacrine cells, t...
متن کاملP 341 Effect of ischaemia on serotonin neurones in the rabbit retina
EFFECT OF ISCHAEMIA ON SEROTONIN NEURONES IN THE RABBIT RETINA. CAZEVIEILLE C. and OSBORNE N.N. Nuftield Laboratory of Ophthalmology, University of Oxford, Oxford OX2 6AW, 1J.K. Serotonin is normally not present in sufficient concentrations in the rabbit retina for localisation by inununohistrxhemisby. The amine is taken up by a population of amacrine cells in the intact retina and in primary r...
متن کاملEvidence for a D4 dopamine receptor decreasing serotonin N-acetyltransferase activity in chick retina.
INTRODUCTION. In vertebrate retina melatonin (MEL) level and activity o f serotonin N-acetyltransferase (NAT; a key regulatory enzyme in MEL biosynthetic pathway) fluctuate with a light-dependent circadian rhythm, with peak values at night. The nocturnal increase o f MEL synthesis is dramatically suppressed by acute exposure o f animals to light (1). Experimental evidence suggest that the inhib...
متن کاملVariations of dopamine, serotonin, and amino acid concentrations in Noda epileptic rat (NER) retina.
Noda epileptic rats (NER) exhibit frequent spontaneous tonic-clonic convulsions which represent a valuable model of human epilepsy. If implication of brain neurotransmitters was largely reported, little is known about retina. However, it has been reported that human epilepsy syndrome varies not only with the location of seizure foci but also according to rhythmic patterns, for which retina has ...
