A schematic of a patch clamp chip showing a gigaseal, whole cell recording configuration, and the ion channel and whole cell currents. Many types of systems have been developed for patch clamping cells in suspension cultures. One system uses a traditional pipette and cells in a droplet suspension culture to obtain patch clamp recordings (see ...
Classical patch clamp setup, with microscope, antivibration table, and micromanipulators. During a patch clamp recording, a hollow glass tube known as a micropipette or patch pipette filled with an electrolyte solution and a recording electrode connected to an amplifier is brought into contact with the membrane of an isolated cell.
The clamp measures the current and other circuitry the voltage; the true power is the product of the instantaneous voltage and current integrated over a cycle. Comprehensive meters designed to measure many parameters of electrical energy ( power factor , distortion , instantaneous power as a function of time, phase relationships, etc.), use ...
The current clamp technique records the membrane potential by injecting current into a cell through the recording electrode. Unlike in the voltage clamp mode, where the membrane potential is held at a level determined by the experimenter, in "current clamp" mode the membrane potential is free to vary, and the amplifier records whatever voltage ...

Several techniques such as intracellular recording, patch-clamp, and voltage-clamp technique, pharmacology, confocal imaging, molecular biology, two photon laser scanning microscopy and Ca 2+ imaging have been used to study activity at the cellular level. Cellular neuroscience examines the various types of neurons, the functions of different ...
The ERMA logo. ERMA (Electronic Recording Machine, Accounting) was a computer technology that automated bank bookkeeping and check processing.Developed at the nonprofit research institution SRI International under contract from Bank of America, the project began in 1950 and was publicly revealed in September 1955.
A current clamp is a type of transformer with a split core which can be spread apart and clipped onto a wire or coil to either measure the current in it or, in reverse, to induce a voltage. Unlike conventional instruments the clamp does not make electrical contact with the conductor or require it to be disconnected during attachment of the clamp.
