: L-Dopa treatment was not administered daily but only acutely for recording sessions. The L-Dopa methyl ester/benserazide doses given s.c during the recordings were 95/24 mg for Br and 90/22.5 mg for Ch. TCD = total cumulative dose of MPTP. MDS = motor disability score in the “OFF” or “ON” state (scale range 0–39). F = female; M = male; GPi = globus pallidus internus.
