'''Beta waves''', or '''beta rhythm''', are [[neural oscillation]]s (brainwaves) in the [[human brain|brain]] with a [[frequency]] range of between 12.5 and 30 [[Hertz|Hz]] (12.5 to 30 [[cycles per second]]). Several different rhythms coexist, with some being inhibitory and others excitory in function.{{cite journal |last1=Rassi |first1=Elie |last2=Lin |first2=Wy Ming |last3=Zhang |first3=Yi |last4=Emmerzaal |first4=Jill |last5=Haegens |first5=Saskia |date=2023 |title=β Band Rhythms Influence Reaction Times |journal=eNeuro |volume=10 |issue=6 |doi=10.1523/ENEURO.0473-22.2023 |issn=2373-2822 |pmc=10312120 |pmid=37364994}} |

Beta waves can be split into three sections: Low Beta Waves (12.5–16 Hz, "Beta 1"); Beta Waves (16.5–20 Hz, "Beta 2"); and High Beta Waves (20.5–28 Hz, "Beta 3").{{cite journal | vauthors=Rangaswamy M, Porjesz B, Chorlian DB, Wang K, Jones KA, Bauer LO, Rohrbaugh J, O'Connor SJ, Kuperman S, Reich T, Begleiter | title=Beta power in the EEG of alcoholics | journal=Biological Psychology | volume=52 | issue=8 | year=2002 | pages=831–842 | pmid=12372655 | doi=10.1016/s0006-3223(02)01362-8| s2cid=26052409 }} Beta states are the states associated with normal [[wakefulness|waking consciousness]]. |
