This exploratory study seeks to examine M1 receptor availability in SZ patients and to relate
M1 receptor availability to proximal and distal measures of cognitive performance, namely
evoked ɣ oscillations in the EEG and verbal memory. Furthermore, the relationship between
hippocampal [11C]EMO availability (BPND), evoked ɣ oscillations, verbal memory, and measures
of illness severity will be explored.
