A sharp high-amplitude negative wave followed by a smaller, slower, positive wave is called:
A) a sleep spindle.
B) a K-complex.
C) a slow-wave.
D) REM.

Question

Quizplus · Accepted Answer

The description matches the characteristics of a K-complex, which is a common EEG waveform during non-REM sleep. It is characterized by a sharp negative wave followed by a slower, positive wave. Sleep spindles are more like a burst of oscillatory brain activity, slow-waves are high-amplitude, low-frequency waves, and REM is a stage of sleep characterized by vivid dreams and rapid eye movements.
