Summary[edit]

Description
English: Video demonstrates behavioural response to acute blue (470 nm) light exposure in OPN4 -/- mouse. The original video of 3 h have been cut down to 1 h and 4 min (2 min darkness before and after 1 h light pulse) and accelerated eight times. The acute light exposure is indicated by text in the upper left corner in the video. Opn4-/- mouse exposed to blue light exhibits comparable change of activity to behaviourally defined-sleep compared to Opn4-/- mouse exposed to green light (S4 Video). The general activity lasted for 14–15 min before sleep induction. Noticeable shortly before sleep induction Opn4-/- mouse exposed exhibits intensive grooming.
