Effect exciting zona incerta GABAergic cells or NRT GABAergic cells on active avoidance responses. A, Effect of low-power and medium-power blue light applied in the zona incerta on ACS+LCS trials for animals that express ChR2 in zona incerta GABAergic cells (Vgat-ZI-ChR2). The right panels show trial speed, trial velocity, and intertrial speed for the data in the left panels. The x-axis denotes blue light frequency trains of 1-ms pulses (Hz) or continuous pulses (Cont). B, Effect of medium-power and high-power blue light applied in the NRT on ACS+LCS trials for animals that express ChR2 in NRT GABAergic cells (Vgat-NR-ChR2). The right panels show trial speed, trial velocity, and intertrial speed for the data in the left panels. The x-axis denotes blue light frequency trains of 1-ms pulses (Hz) or continuous pulses (Cont).
