The neurohormone melatonin is synthesized by the pineal gland under the stimulation of norepinephrine (NE). Its synthesis is inhibited by acetylcholine (ACh) and by insulin. Type 2 diabetic Goto Kakizaki (GK) rats have higher insulin and lower melato

In normal subjects the later part of the cone a-wave to a brief flash increases in amplitude after 50–100ms darkness due to a contribution from secondary hyperpolarising cells. We recorded these responses along with clinical ON and OFF ERGs in pati

Retinas from a strain of rabbits with low dark-adapted electroretinographic (ERG) b-wave amplitudes, and declining ERG responses with time, were examined by light and electron microscopy. Seven rabbits from the affected strain (13 months to 5 years o

When used as an antiepileptic drug in humans vigabatrin, which is a GABA analogue and an inhibitor of GABA-aminotransferase, often causes peripheral visual field loss. This could result from increases in endogenous GABA levels. Accordingly we have in

HEPES-buffered solutions, mostly used in studies of isolated cells, and bicarbonate-buffered solutions, mostly used in studies of isolated retinal tissues, have both been used to superfuse an isolated rabbit retina preparation. The responses of horiz

In the retinas of Royal College of Surgeons (RCS) rats light induces an increase in distal extracellular potassium irrespective of the age, between days 19–24 and days 29–35 postpartum, but by days 29–35 the ERG b-wave has become reduced. The s

When preparing isolated rabbit retinas we found in some animals fundi which were not uniformly dark but had abnormal areas of red coloration. The in situ electroretinograms (ERG) of 82 rabbits recorded after 1 h of dark adaptation were checked for ab

When the retinas of some fishes and amphibians are dark-adapted the hyperpolarising response of horizontal cells (HCs) to a light stimulus is suppressed (= dark suppression) but is restored to that of light adaptation when a light stimulus is rapidly

An increase in the amplitude of horizontal cell (HC) potentials, a decrease in the extracellular potassium around the photoreceptors and an increase in the PIII component of the ERG that occur with increasing light stimulus intensity are shown to be

Although the rising phase of the b-wave seems to be generated mainly in the rod bipolar cells and the cone on-bipolar cells, the slow component of the electroretinogram, the c-wave, evidently originates in the Müller cells and the pigment epithelium
