spike-wave activity

the pattern produced by an action potential of a neuron when amplified and projected onto the screen of an oscilloscope or a computer monitor. The waveform appears as a sharp, high peak, followed by a short dip below the baseline (the afterpotential), then a return to the predischarge level. The amplitude of the wave spike indicates the intensity of the discharge.
