Whole cell patch clamp for investigating the mechanisms of infrared neural stimulation.
It has been demonstrated in recent years that pulsed, infrared laser light can be used to elicit electrical responses in neural tissue, independent of any further modification of the target tissue. Infrared neural stimulation has been reported in a variety of peripheral and sensory neural tissue in vivo, with particular interest shown in stimulation of neurons in the auditory nerve. However, wh...
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 کاملPatch clamp techniques for single channel and whole-cell recording
The patch clamp technique was first used by Neher and Sakmann (1976) to resolve currents through single acetylcholine-activated channels in cell-attached patches of membrane of frog skeletal muscle. The method they used (described by Neher, Sakmann & Steinbach, 1978) and subsequent refinements (Hamill, Marty, Neher, Sakmann & Sigworth, 1981) have led to techniques for high resolution recording ...
متن کاملMeasurement of cellular excitability by whole cell patch clamp technique.
Patch clamp method developed more than 30 years ago is widely used for investigation of cellular excitability manifested as transmembrane ionic current and/or generation of action potentials. This technique could be applied to measurement of ionic currents flowing through individual (single) ion channels or through the whole assembly of ion channels expressed in the whole cell. Whole cell confi...
متن کاملRobust, high-resolution, whole cell patch-clamp capacitance measurements using square wave stimulation.
High-resolution, whole cell capacitance measurements are usually performed using sine wave stimulation using a single frequency or a sum of two frequencies. We present here a high-resolution technique for whole-cell capacitance measurements based on square-wave stimulation. The square wave represents a sum of sinusoidal frequencies at odd harmonics of the base frequency, the amplitude of which ...
