PET imaging visualizing PSAM4-5HT3 expression in the cortex and its projection sites. A, Illustration and MR image of the location of the second vector injection site. The vector was injected in three tracks within the right MI, shown as red dots in the illustration. B, The SUVR images contrasting 42 d after the second and first vector injection. Increased SUVR was observed in the right MI (left, red arrow) and left CDt (left, cyan arrow). Other projection sites, such as the left MI (left, red arrowhead), right PUT (left, white arrowhead), and right thalamus (right, yellow arrowhead), also showed increased SUVR. Data obtained from MK#1. MI, primary motor cortex, P, posterior, D, dorsal, A, anterior, R, right.
