Figure 5.
Histogram showing the relative abundance of labeled elements for DARPP-32 and I-1 in the neuropil of monkey PFC area 9. The distribution of immunoreactive profiles is significantly different between the proteins (χ2 = 41.237; p < 0.0001). Post hoc analysis revealed that a larger percentage of I-1 label is found in axon terminals, while DARPP-32 label is found more frequently in glia.
