Effect of local injection of the D2 receptor antagonist sulpiride on STN‐ and GPi‐HFS‐induced suppression of TAN firing (population histograms). (a, d) Pre‐injection; (b, e) 2 min after injection; and (c, f) 6 min after injection. The STN‐HFS‐induced suppression of TAN firing was transiently blocked by local injection of sulpiride (a–c). The GPi‐HFS‐induced suppression of TAN firing was not blocked by local injection of sulpiride (d–f). The stimulation lasted 10 s. N indicates the number of neurons.
