This picture shows the pre/post cannabis music changes in the group
average mappings for the four subjects. Decrease of δ-, θ-, and β-
amplitudes was a constant observation throughout the individual averages of
the four subjects and was observed in GA of the four persons, too. THC is
known to decrease the cell firing rates. Maybe this amplitude-decrease of is
due to decreased cell firing rates. Comparing the left with the right
mapping, in the left higher amplitudes, especially on δ- and θ- range in the
upper row, but also on centro-parietal β-areas in the below, can be
observed. In temporal areas the θ-decrease is remarkable, so let us take a
closer look on the post-Cannabis Music GA.
