Unreferenced date December 2006 A synaptic potential also known as a postsynapticpotential is an alteration in the membrane potential of a cell resulting from activation of a chemical synapse synaptic input . All animal cells maintain a voltage difference between the intracellular and extracellular regions, holding the intracellular region at a negative voltage that in a baseline state is usually in the range 30 to 70 millivolts. Synaptic inputs from neuron s can alter this voltage difference. If the intracellular voltage rises, the signal is called an excitatory postsynapticpotential EPSP if it falls the signal is called an inhibitorypostsynapticpotential IPSP . If the cell is electrically excitable, a sufficiently large EPSP may cause it to generate an action potential . Category Cell biology Neuroscience stub Medicine stub ... more details

Refimprove date January 2008 In economics , potential output also referred to as natural gross domestic product refers to the highest level of real vs. nominal in economics real Gross Domestic Product output that can be sustained over the long term. The existence of a limit is due to natural and institutional constraints. If actual GDP rises and stays above potential output, then in the absence of wage and price controls inflation tends to increase as demand exceeds supply and demand supply . This is because of the limited supply of workers and their time, capital equipment, and natural resources, along with the limits of our technology and our management skills. Graphically, the expansion of output beyond the natural limit can be seen as a shift of production volume above the optimum quantity on the average cost curve. Likewise, if GDP is below natural GDP, inflation will decelerate as suppliers lower prices to fill their excess production capacity. Potential output in macroeconomics corresponds to one point on the production possibilities frontier or curve for a society as a whole seen in introductory economics, reflecting natural, technological, and institutional constraints. Potential output has also been called the natural gross domestic product . If the economy is at potential, the unemployment rate equals the NAIRU or the natural rate of unemployment . There is great disagreement among economists as to what these rates actually are.

Diffuse Noxious Inhibitory Controls DNIC refers to an endogenous pain modulatory pathway which has often been described as pain inhibits pain . ref name LeBars1979 Le Bars D, Dickenson AH, Besson JM June 1979 . Diffuse noxious inhibitory controls DNIC . I. Effects on dorsal horn convergent neurones in the rat . Pain 6 3 283 304. PMID 460935. ref It occurs when response from a painful stimulus is inhibited by another, often spatially distant, noxious stimulus. Mechanism Noxious stimuli activate the endings of nociceptor nociceptive C fiber C and A delta fiber A delta nerve fibers, which carry the signal to neurons in the posterior horn of spinal cord dorsal horn of spinal cord. DNIC refers to the mechanism by which dorsal horn wide dynamic range neuron s responsive to stimulation from one location of the body may be inhibited by noxious stimuli such as heat, high pressure or electric stimulation applied to another, remote location in the body. ref name LeBars1979 The inhibition is thought to originate in the brain, and is thought to affect both wide dynamic range and nociception specific neurons in the dorsal horn ref name LeBars2002 Le Bars D October 2002 .

Orphan date September 2008 Expressive potential is the degree to which a given MIDI controller music control interface input device enables a musician to control musical expression . An interface with low expressive potential enables control over a narrow range of musical expression, no matter how virtuoso virtuosic its player, whereas an interface with high expressive potential enables control over a wide range of musical expression. Expressive potential is independent of how that potential was, is, or will be realized in any given composition or performance. This independence allows the expressive potential of new musical instruments & interfaces to be compared and contrasted objectively with traditional musical instruments. The concept of expressive potential is closely related to the concept of affordance , i.e. all action possibilities latent in the environment, objectively measurable and independent of the individual s ability to recognize or realize them. One possible metric for expressive potential is the number of Degrees of freedom physics and chemistry degrees of freedom provided by the interface. The more degrees of freedom, the more independent expressive variables a musician can control independently during performance. The development of new interfaces to control musical expression is an active research area, supporting an annual conference, http nime.org New Interfaces for Musical Expression .
