Effects of optogenetic stimulation on ChR2-expressing M/TCs with different light intensities

(A) Averaged MCL field potentials induced by the first blue light (473 nm) pulse delivered to the OB of P8-11 mice with the light intensity set as 1%, 5% 10% and 20% of the maximal intensity (1.75 mW) of laser power. The corresponding light intensities measured at the tip of the optrode are indicated following the percentage. The 3-ms light square pulses are denoted by light blue bars.

(B) Raster plots of OB neuronal firing in response to the first blue light pulse delivered in M/TCs of P8-11 mice at the corresponding intensity in (A).
