Show Summary Details


Evoked potentials are those components of the EEG that arise in response to a stimulus (which may be electric, auditory, visual, etc.). Such signals are usually below the noise level and thus not readily distinguished, and one must use a train of stimuli and signal averaging to improve the signal-to-noise ratio. Single-neuron behavior can be examined through the use of microelectrodes which impale the cells of interest. Through studies of the single cell, one hopes to build models of cell networks that will reflect actual tissue properties.

Keywords: evoked potential; EEG; signal-to-noise ratio; microelectrodes; cell networks; tissue properties
