WitrynaGamma wave. A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 25 and 140 Hz, the 40 Hz point being of particular interest. [1] Gamma rhythms are correlated with large scale brain network activity and cognitive phenomena such as working memory, attention, and perceptual grouping, … WitrynaFrequency of a wave is the number of waves passing a point in a certain time. The unit of frequency is hertz (Hz) which is equal to one wave per second. Define amplitude of a wave. Amplitude is the maximum displacement from the neutral position. This represents the energy of the wave. Greater amplitude carries greater energy.
