Patch clamp recordings from mouse retinal neurons in a dark-adapted slice preparation.
Our visual experience is initiated when the visual pigment in our retinal photoreceptors absorbs photons of light energy and initiates a cascade of intracellular events that lead to closure of cyclic-nucleotide-gated channels in the cell membrane. The resulting change in membrane potential leads in turn to reductions in the amount of neurotransmitter release from both rod and cone synaptic term...
متن کاملRecording light-evoked postsynaptic responses in neurons in dark-adapted, mouse retinal slice preparations using patch clamp techniques.
The retina is the gateway to the visual system. To understand visual signal processing mechanisms, we investigate retinal neural network functions. Retinal neurons in the network comprise of numerous subtypes. More than 10 subtypes of bipolar cells, ganglion cells, and amacrine cells have been identified by morphological studies. Multiple subtypes of retinal neurons are thought to encode distin...
متن کاملSimultaneous Whole-cell Recordings from Photoreceptors and Second-order Neurons in an Amphibian Retinal Slice Preparation
One of the central tasks in retinal neuroscience is to understand the circuitry of retinal neurons and how those connections are responsible for shaping the signals transmitted to the brain. Photons are detected in the retina by rod and cone photoreceptors, which convert that energy into an electrical signal, transmitting it to other retinal neurons, where it is processed and communicated to ce...
متن کاملWhole-Cell Patch-Clamp Recordings
The patch-clamp recording technique, which measures ionic currents under voltage clamp, was designed to study small patches of membranes in which near perfect control of the transmembrane voltage can be achieved readily. The recent application of patch-clamp methodology to the analysis of whole-cell current actually defies many of the original design requirements. Nevertheless, whole-cell recor...
متن کاملHigh-fidelity patch-clamp recordings from neurons cultured on a polymer microchip.
We present a polymer microchip capable of monitoring neuronal activity with a fidelity never before obtained on a planar patch-clamp device. Cardio-respiratory neurons Left Pedal Dorsal 1 (LPeD1) from mollusc Lymnaea were cultured on the microchip's polyimide surface for 2 to 4 hours. Cultured neurons formed high resistance seals (gigaseals) between the cell membrane and the surface surrounding...
