Abbreviations: HR, heart rate; MAP, mean arterial blood pressure.

Telemetric blood pressure and HR recordings in rats habituated to the plethysmography chamber during various states of vigilance. No change in resting MAP or HR was observed during photostimulation of Arch⁺ or ChR2⁺ rats. Statistics: two-way ANOVA.
