Electron microscopy of Golgi preparations of goldfish retina shows that dendrites of type a (hyperpolarizing,
off-center) bipolar cells make wide cleft junctions unassociated with synaptic …

Vertebrates can detect light intensity changes in vastly different photic environments, in part,
because postreceptoral neurons undergo “network adaptation.” Previous data implicated …

Immunohistochemical and ex vivo anatomical studies have provided many glimpses of the
variety, distribution, and signaling components of vertebrate retinal neurons. The beauty of …

Dopamine can regulate signal generation and transmission by activating multiple receptors
and signaling cascades, especially in striatum, hippocampus, and cerebral cortex. …

The amino acids L-glutamate and L-aspartate depolarize H1 horizontal cells in the perfused
goldfish retina but only at millimolar concentrations. The effects of L-glutamate (but not of L-…

The spike output of neural pathways can be regulated by modulating output neuron excitability
and/or their synaptic inputs. Dopaminergic interneurons synapse onto cells that route …

Effects of L‐glutamate and its analogues on membrane potentials of solitary horizontal cells
were studied by intracellular recording. L‐glutamate depolarized these cells at micromolar …

We tested whether dopamine receptor activation modulates the voltage-gated Na + current
of goldfish retinal ganglion cells, using a fast voltage-clamp amplifier, perforated-patch whole …

1. Using whole cell patch-clamp methods, we have identified an inward cationic current
activated by hyperpolarization (Ih) in somata of goldfish retinal ganglion cells. 2. Ih activated at …

Antisera directed against hyperpolarization-activated mixed-cation (“I h ”) and K + (“K ir ”)
channels bind to some somata in the ganglion cell layer of rat and rabbit retina. Additionally, …
