Effect of gabazine in L4. A and B: effect of gabazine on mean whisker tuning curves in control (A) and in D1-spared (B) animals. Numbers denote the fractional increase in mean spike count. Insets: recording sites for each population of units. C and D: quantification of gabazine effect by gabazine/predrug response ratio for all units with nonzero predrug responses. Black, all units with non-0 predrug responses to D1–D3. Gray, all units with non-0 predrug responses to D1 and D2. C: control animals. D: D1-spared animals. E: comparison of disinhibition of D1 and D2 whisker responses for individual neurons. F: change in the D1-dominance index by gabazine, for individual units in control and D1-spared animals. Gabazine preferentially disinhibited D1 responses and increased the D1-di for most units in control and D1-spared animals.
