“…However, depending on the challenge more or less regions were involved. This increase of spectral delta power indicates a major involvement of the cholinergic transmitter system during processing of cognitive as well as emotional challenges not only confined to lateral prefrontal brain [2]. The same pattern was seen with respect to theta power, where also only increases were documented during the different challenges.…”

“…Direct measurement of electric activity provides much more information by use of frequency analysis obtained by Fast Fourier Transformation (FFT), since single frequencies have been related to neurotransmitter activities. For example, slow delta waves seem to be under the control of acetylcholine [2]. Spectral power of theta waves changes in the presence of norepinephrine alpha2 receptor agonists [3].…”

“…Other authors also have recently documented higher delta values for subjects suffering from mild cognitive impairment in comparison to healthy volunteers and reported on further alterations typical for those seen in Alzheimer's disease [22]. Higher power in the delta frequency range indicates lower activity of the cholinergic transmitter system [23]. In animal lesion studies, increased delta activity has been reported after destruction of the Nucleus Basalis [24], the main production site of acetylcholine [25].…”

“…Many experimental works have shown that drugs affect EEG characteristics in humans and rodents in a similar manner [Dimpfel et al, 1992;Jongsma et al, 1998a,b Coenen andDimpfel, 2005]. In addition, a substantial body of studies suggest a relation between memory performance and EEG.…”
