Retinal bipolar cell input mechanisms in giant danio. III. ON-OFF bipolar cells and their color-opponent mechanisms.
TLDR
Recordings from morphologically identified cone-driven on-off bipolar cells in giant danio retinal slices are consistent with the hypothesis that both EAATs and AMPA/kainate receptors are involved in the generation of light-evoked responses in Cabs and that they confer these cells with on and off bipolar cell properties, respectively.

TLDR
The present study confirms the general notion that AMPA EAAR- mediated currents are transient and NMDA receptor-mediated currents are sustained, and current-voltage relations of the light-evoked EPSC at different time points showed the contributions of these two receptor types significantly overlap.
Retinal bipolar cell input mechanisms in giant danio. I. Electroretinographic analysis.
TLDR
Under scotopic conditions, rod and cone inputs onto on bipolar cells were studied and the sensitivities of the b-wave to photopically matched green and red stimuli were compared to determine which receptor types mediate synaptic transmission from rods and cones to on and off bipolar cells.
Glutamatergic mechanisms in the outer retina of larval zebrafish: analysis of electroretinogram b- and d-waves using a novel preparation.
TLDR
The investigation of the pharmacology of cone photoreceptor inputs onto bipolar cells in larval zebrafish found that an excitatory amino acid transporter (EAAT) presumably linked to a Cl() channel mediates most of the synaptic transmission from thecone photoreceptors to the ON bipolar cells, although metabotropic glutamate receptors (presumably mGluR6) also make a small contribution.
Response characteristics and receptive field widths of on‐bipolar cells in the mouse retina
TLDR
The results suggest that this limit to spatial resolution could be imposed early in the visual system by the size of the bipolar cell receptive fields.

TLDR
The cGMP- activated channel in bipolar cells seems novel, fundamentally different from those found in photoreceptor cells or olfactory receptor cells.

TLDR
It is concluded that the rod bipolar cell in situ is depolarized at light onset.
Horizontal cells isolated from catfish retina contain two types of excitatory amino acid receptors.
TLDR
KA was the most efficacious of the agonists resulting in the largest Imax and this desensitization could be removed by pretreatment with conconavalin A (Con A).
Neurotransmitter‐induced currents in retinal bipolar cells of the axolotl, Ambystoma mexicanum.
TLDR
By whole‐cell patch clamping cells in retinal slices, the synaptic transmitter released by photoreceptors was shown to close channels with an extrapolated reversal potential around ‐3 mV in depolarizing bipolar cells, and increase the membrane current noise.

TLDR
The results show that the G-protein(s) linking glutam ate receptors to a cG M P cascade in onbipolar cells possess sites which are ADP-ribosylated by pertussis and cholera toxins, with no homology to the adenylate cyclase system but possibly with a homologies to transducin.
Suppression by glutamate of cGMP-activated conductance in retinal bipolar cells
TLDR
The DBC glutamate receptor seems to close ion channels by increasing the rate of cGMP hydrolysis by a G protein-mediated process that is strikingly similar to light transduction in photoreceptors.
Magnesium gates glutamate-activated channels in mouse central neurones
TLDR
The voltage dependence of the NMDA receptor-linked conductance appears to be a consequence of the voltage dependenceof the Mg2+ block and its interpretation does not require the implication of an intramembrane voltage-dependent ‘gate’.

TLDR
On-bipolar cell cGMP-activated channel was blocked by L-cis-diltiazem, a block which was strongly voltage dependent, but this channel is not identical with that of photoreceptors.

TLDR
The results indicate that the glutamate receptors of on-bipolar cells are coupled via a G-protein to regulate intracellular cGMP, which, in turn, results in the opening of sub-synaptic membrane channels.
