What are the effects of methylphenidate (Ritalin) on the EEG?

: decrease in all frequency bands, excepting gamma, where we see an increase in amplitude.

; decrease in slow activity and an increase in beta from 12-26Hz.

; decrease in delta and theta, increase in posterior alpha, increase in low beta amplitudes.

; decrease in Beta 2 and Beta 3, with an increase in alpha amplitudes.
