Suppression by glutamate of cGMP-activated conductance in retinal bipolar cells
Nature, 1990Depolarizing bipolar cells (DBCs) of the retina are the only neurons in the vertebrate central nervous system known to be hyperpolarized by the neurotransmitter glutamate. Both glutamate and its analogue L-2-amino-4-phosphonobutyrate (APB) hyperpolarize DBCs by decreasing membrane conductance.

Cerebellar Purkinje cell markers are expressed in retinal bipolar neurons
Journal of Comparative Neurology, 1991AbstractPrevious studies have been directed at the elucidation of neuron‐specific gene expression in the mammalian central nervous system. In particular, we have identified a series of marker molecules that are expressed in cerebellar Purkinje cells with varying degrees of specificity. Here, we show by light microscopic immunocytochemistry and Northern

Retinal bipolar cells with double colour-opponent receptive fields
Nature, 1981Cells with colour opponency in each of two spatially antagonistic parts of their receptive fields, have been found at various stages of the visual pathways in several animal species1–8. These cells, which are said to have ‘double colour-opponent receptive fields’, are thought to play a major role in the analysis of coloured images by enhancing ...

Dark noise in retinal bipolar cells and stability of rhodopsin in rods
Nature, 1977FOR the dark-adapted human observer, the absolute visual threshold has been estimated to be the effective absorption of 5–10 photons in an area covered by some 500 rods1. Although the quantum statistics of light enter as a factor which determines the frequency of seeing weak light stimuli1,2, it has been suggested that there is ‘noise’ in the visual ...

The unitary event amplitude of mouse retinal on-cone bipolar cells
Visual Neuroscience, 2003Light-evoked synaptic currents were recorded from on-cone bipolar cells in the mouse retina. Fluctuations in the synaptic current observed during maintained light steps were analyzed in order to estimate the amplitude of the underlying unitary event. The maximal synaptic current variance was 5-fold larger than the maximum expected from fluctuations in ...

Retinal bipolar cell types differ in their inventory of ion channels
Visual Neuroscience, 2006Bipolar cells were recorded in rat retinal slices to study the distribution of hyperpolarization-activated and cyclic nucleotide-gated (HCN) channels. Patch-clamp whole cell measurements were combined with intracellular filling and recorded cells were morphologically identified. HCN channel isoforms HCN1-4 are differentially expressed in bipolar cells.

Neurochemical heterogeneity of retinal bipolar cells.
Optometry (St. Louis, Mo.), 2003Retinal bipolar cells show neurochemical changes in response to retinal insult, which could have profound effects on retinal function or recovery after insult however, the neurochemistry of bipolar cells is incompletely understood. METHODS The distribution of the amino acid neurotransmitters glutamate, gamma-aminobutyric acid (GABA), and glycine, and ...
