Table 2.

Lack of effect of MPTP treatment on ppN/OFQ mRNA-expressing neurons in the VTA, nucleus of Darkschewitsch (DK) and in dentate gyrus (DG) of hippocampus.

ppN/OFQ+ cells/mm2
Treatment VTA DK DG
Controls (6) 7.0 ± 1.7 220 ± 50 34.8 ± 3.1
MPTP, 7 days (8) 6.9 ± 2.6 150 ± 34 28.9 ± 4.00
P value P = 0.949 P = 0.253 P = 0.294

The table reports the numbers of ppN/OFQ mRNA-expressing neuronal cells or cell clusters/mm2 in three brain regions, the VTA, the DK, and the DG of hippocampus (see Methods for details). MPTP treatment 7 days previously did not significantly alter the numbers of cells expressing ppN/OFQ mRNA in any of these brain regions (analysis by t-test). The numbers in parentheses after each treatment indicate the numbers of animals receiving this treatment.
