• Excitatory postsynaptic potential — In neuroscience, an excitatory postsynaptic potential (EPSP) is a temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell. They are the opposite of inhibitory… …   Wikipedia

• Wood's metal — Wood s metal, also known as Lipowitz s alloy or by the commercial names cerrobend, bendalloy, pewtalloy or MCP 158, is a eutectic, fusible alloy with a melting point of approximately 70 °C (158 °F). It is a eutectic alloy of… …   Wikipedia

• Population spike — In neuroscience, a population spike (PS) is the shift in electrical potential as a consequence of the movement of ions involved in the generation and propagation of action potentials. Population spikes often reflect synaptically induced firing… …   Wikipedia

• Electrophysiology — (from Greek gr. ἥλεκτρον, ēlektron , amber [see the etymology of electron ] ; gr. φύσις, physis , nature, origin ; and gr. λογία, logia ) is the study of the electrical properties of biological cells and tissues. It involves measurements of… …   Wikipedia

• Local field potential — A local field potential (LFP) is a particular class of electrophysiological signals, which is related to the sum of all dendritic synaptic activity within a volume of tissue. BackgroundA signal is recorded using a low impedance extracellular… …   Wikipedia

• Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… …   Wikipedia

• Single-unit recording — In neurophysiology, single unit recording is the use of an electrode to record the electrophysiological activity (action potentials) from a single neuron. An electrode introduced into the brain of a living animal will detect electrical activity… …   Wikipedia

• Current sources and sinks — are analysis formalisms which distinguish points, areas, or volumes through which current enters or exits a system. While current sources or sinks are abstract elements used for analysis, generally they have physical counterparts in real world… …   Wikipedia

• Electroencephalography — (EEG) is the measurement of electrical activity produced by the brain as recorded from electrodes placed on the scalp.Just as the activity in a computer can be understood on multiple levels, from the activity of individual transistors to the… …   Wikipedia

• Quantitative models of the action potential — In neurophysiology, several mathematical models of the action potential have been developed, which fall into two basic types. The first type seeks to model the experimental data quantitatively, i.e., to reproduce the measurements of current and… …   Wikipedia
