“ Olanzapine and risperidone, but not quetiapine, produced even greater up-regulation of D(4) receptors in CPu (61%, 37%), NAc (65%, 32%), and HIP (61%, 37%).”
“ Olanzapine and risperidone, but not quetiapine, significantly increased D(2) binding in medial prefrontal cortex (MPC; 67% and 34%), caudate-putamen (CPu; average 42%, 25%), nucleus accumbens ( NAc ; 37%, 28%), and hippocampus (HIP; 53%, 30%).”
