Reversal performance and forebrain NE depletion after DSP-4 treatment in C57BL/6J mice
Vehicle | DSP-4 | |
Reversal performance | ||
Total trials | 171 ± 5 | 157 ± 8 |
Total errors | 94 ± 4 | 90 ± 4 |
Total correction errors | 364 ± 34 | 400 ± 34 |
Perseveration index | 3.7 ± 0.4 | 4.7 ± 0.6 |
Total trials omitted | 9.2 ± 5.0 | 23.5 ± 7.8 |
Average stimulus reaction time (s) | 3.8 ± 0.4 | 4.3 ± 0.5 |
Average reward retrieval latency (s) | 2.0 ± 0.1 | 2.1 ± 0.2 |
NE tissue content | ||
mPFC (ng/g) | 395.4 ± 68.5 | 222.9 ± 30.3 (−43.6%)* |
Hippocampus (ng/g) | 412.3 ± 35.3 | 238.0 ± 33.0 (−42.3%)* |
5-HT tissue content | ||
mPFC (ng/g) | 397.8 ± 46.4 | 397.8 ± 73.6 (−5.9%) |
Hippocampus (ng/g) | 448.6 ± 55.2 | 423.8 ± 30.1 (−4.6%) |
DSP-4 treatment did not significantly affect any measure of reversal performance, despite significantly reducing tissue content of NE (but not 5-HT) in the mPFC and hippocampus. n = 10 per treatment. Data are means ± standard errors of the mean.
*P < 0.05 versus vehicle.
