Results of the quantitative analysis of the number (#) and percentage (%) of labeled (+) and unlabeled (neg) profiles counted using stereology and simple profile counts (SPC) from the caudate nucleus, the putamen, and the combined totals (C+P).

Labeled axon terminals (+AT) forming synapses on spines and dendrites.

Labeled axon terminals (+AT) forming symmetric (sym) vs. asymmetric (asym) synapses. AS, asymmetric axospinous; AD, asymmetric axodendritic; SS, symmetric axospinous; SD, symmetric axodendritic.

Labeled axon terminals (+AT) forming synapses on labeled (+) spines or dendrites (sp,den), or on unlabeled (neg) spines or dendrites (sp,den).
