Separation by dopamine responses | Percentage of units a | Baseline rate (Hz) |
---|---|---|
Increased activity (D1) | 64% | 25 ± 1.3 |
Decreased activity (D2) | 34% | 33 ± 1.7* |
All units were separated according to dopamine responses, as increased or decreased activity (n = 140).
↵ aThe proportion of neurons with each response was compared with the expected 50% each by χ 2 test, p < 0.001.
↵*p < 0.001 (mean ± SEM); firing rates were compared between both groups of dopamine responses (unpaired t test).
