“…Intra-individual stability of the whole EEG-Gestalt in rest and activation replicated findings on personality and situational sensitivity of the EEG (Davidson and Hugdahl 1996;Hagemann et al 1999;Koukkou and Lehmann 1978;Machleidt, Gutjahr, and Mügge 1989). The α-focus in parietal regions showed individual topographic shapes of receptive activity.…”

ABSTRACT. An explorative study on cannabis and music perception is presented, conducted in a qualitative and quantitative way in a habituated setting. EEG-brainmapping data (4 subjects; rest-pre/post listening; 28 EEG traces; smoked cannabis containing 20 mg delta-9-THC with tobacco) were averaged and analyzed with a T-Test and a visual topographic schedule. Compared to pre-THC-rest and pre-THC-music, the post-THC-music EEG showed a rise of alpha percentage and power in parietal cortex on four subjects, while other frequencies decreased in power. Comparing pre/post music EEGs, differences (p < 0.025) were also found in the right fronto-temporal cortex on theta, and on alpha in left occipital cortex. Results represent an inter-individual constant EEG correlate of altered music perception, hyperfocusing on the musical time-space and cannabis-induced changes on perception of musical acoustics. Cannabis might be of help for hearing impaired persons.

“…Higher asymmetry scores indicate greater relative left frontal activity. before, many researchers currently favor a motivational model of EEG asymmetry over the valence model (see Davidson, 1992Davidson, , 1995Davidson, , 1998Hagemann et al, 1998Hagemann et al, , 1999Debener et al, 2001). The motivational model would predict greater relative right frontal activity during the aversive slide condition only if the participants were motivated to withdraw or engage in withdrawal related behavior while viewing the aversive slides.…”

“…Empirical studies, however, yielded inconsistent findings. While some studies found evidence in favor of Eysenck's hypothesis of a weaker cortical arousal in extraverted as compared to introverted individuals (e.g., Gale et al, 2001;Tran et al, 2001), other studies failed to find such a relationship (e.g., Hagemann et al, 1999;Schmidtke & Heller, 2004;cf. also Gale, 1983).…”
