In neuroscience, single-unit recordings (also, single-neuron recordings) provide a method of measuring the electro-physiological responses of a single neuron using a microelectrode system. When a neuron generates an action potential , the signal propagates down the neuron as a current which flows in and out of the cell through excitable ...
Microneurography exploration of sympathetic efferent system is unique from technical point of view as multiunit recordings have been very prosperous whereas single unit recording is essential with most other systems. Soon after microneurography was launched it was demonstrated that sympathetic activity is much different in muscle and skin nerves.
If the tip is small enough, such a configuration may allow indirect observation and recording of action potentials from a single cell, termed single-unit recording. Depending on the preparation and precise placement, an extracellular configuration may pick up the activity of several nearby cells simultaneously, termed multi-unit recording.
The shock and vibration data is either recorded continuously over a defined time period or on an event-driven basis where the recording of data is determined by certain criteria. Employing such an event-based measurement method allows the recording of specific shocks that exceed a critical length of time or strength.
The term unit record equipment also refers to peripheral equipment attached to computers that reads or writes unit records, e.g., card readers, card punches, printers, MICR readers. IBM was the largest supplier of unit record equipment and this article largely reflects IBM practice and terminology.
The disciplines within which these methods are used is quite broad, ranging from psychology to neuroscience to biomedical engineering to sociology. The following is a list of neuroimaging methods: Electroencephalography (EEG) Quantitative electroencephalography (QEEG) Stereoelectroencephalography (SEEG) Functional magnetic resonance imaging (fMRI)
