Figure 2.

Reconstructed locations of all GPi single-units included in the database. Locations are projected onto parasagittal sections at 1 mm intervals separately for animal G and I, pre- (green) and post-MPTP (magenta). The line drawing delineating the GPi boundary was taken from a standard atlas (89), which was subsequently adjusted to align with the structural MRIs and microelectrode mapping results from individual animals.
