Patch-Clamp Techniques
Research News and Information
Definition of 'Patch-Clamp Techniques'An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used. |

Rundown is ubiquitously seen in response to repetitive activation of receptor or ion channels as a use-dependent down-regulation through various mechanisms. In contrast to AMPA receptors, gamma-aminobutyric acid type A receptor (GABA(A)R) are ... Read more...

Theta oscillations are believed to play an important role in the coordination of neuronal firing in the entorhinal (EC)-hippocampal system but the underlying mechanisms are not known. We simultaneously recorded from neurons in multiple regions of ... Read more...
ELKS2alpha/CAST deletion selectively increases neurotransmitter release at inhibitory synapses.
27 Oct 2009
The presynaptic active zone is composed of a protein network that contains ELKS2alpha (a.k.a. CAST) as a central component. Here we demonstrate that in mice, deletion of ELKS2alpha caused a large increase in inhibitory, but not excitatory, ... Read more...
