This simulated data mimics a PET imaging study where the 5-HT2A receptor and serotonin transporter (SERT) binding potential has been quantified into 8 different regions. The 5-HT2A cortical regions are considered high-binding regions measurements. These measurements can be regarded as proxy measures of the extra-cellular levels of serotonin in the brain
