Contoh salamander

• The interaction of ionic currents mediating single spike activity in retinal amacrine cells of the tiger salamander.

• One salamander was severely affected with associated tissue changes, including accumulations of melanomacrophages.

• The spatial distribution of excitatory and inhibitory inputs to ganglion cell dendrites in the tiger salamander retina.

• Taken together, we thought that it was important to investigate the number and spatial arrangement of major cell populations in the salamander retina.

• The basis for this sustained current in tiger salamander retinal ganglion cells is unknown; perhaps it reflects a biphasic inactivation behavior of one channel type.

• Desensitizing glutamate receptors shape excitatory synaptic inputs to tiger salamander retinal ganglion cells.

• These recordings are of special interest since they are apparently the first to be reported for the land-phase tiger salamander.

• Patch-clamp recordings in salamander retinal slice are also consistent with an active response to depolarization in on-type bipolar neurons.

• Passive electrical cable proper ties and synaptic excitation of tiger salamander retinal ganglion cells.

• Passive electrical cable properties and synaptic excitation of tiger salamander retinal ganglion cells.

• Our data demonstrate that all three major cell types are not uniformly distributed across the salamander retina.

• Two types of glutamate receptors differentially excite amacrine cells in the tiger salamander retina.

• Responses of ganglion cells to contrast steps in the light-adapted retina of the tiger salamander.

• In our present study, we aimed to examine the number and spatial patterns of major cell populations in the salamander retina.

• Identification of glutamate receptor subtypes mediating inputs to bipolar cells and ganglion cells in the tiger salamander retina.
