Fig. 2.
Increase in the number of PV-containing neurons in the GPi of TS patients. (A and B) Cresyl violet staining. (C and D) PV immunostaining. Representative sections from the GPi of NC (A and C) and TS (B and D) are shown. Note the corresponding increase in the density of total neurons and PV-containing neurons in the GPi of TS brains. V indicates blood vessels; arrows indicate neuronal cell bodies. (Scale bar: 100 μm.)
