Figure 5. Light-induced phase-shift of PER2::Luc rhythms using the embedded device or the classical procedure of light stimulation of retinal explants. Each symbol corresponds to an individual retinal explant. Blue symbols correspond to retinal explants exposed to light stimulation (480 nm, 30 min, 10¹⁵ photons/cm²/s) using the classical procedure (left graph) or the embedded device (right graph). Black symbols correspond to retinal explants that were identically handled but not exposed to light (DC).
