Impact of age on the circadian visual system and the sleep-wake cycle in

摘要

Light gray blocks indicate night while white sections of the graph correspond with the day, ZT0 is light on. Distance traveled in centimeters showed significantly higher values for young mice in 24 h (A) and Day/Night (B) profiles. The 24 h profile had significantly higher distance traveled during both the night and day, however when the data were binned into 12 h night and day values, only the nighttime differences were significant. Movement time in seconds showed significantly higher values for young mice in 24 h (C) and Day/Night (D) profiles. For this variable, the timepoints with significant differences were only during the night for both 24 h and dayight profiles. Velocity in centimeters per second showed significantly higher values for young mice in 24 h (E) and Day/Night (F) profiles. Unlike the previous two variables there were significantly difference during both the night and day for 24 h and dayight profiles. *p < 0.05.
