Im confused about this, its circadian Biology; Please help me on this!
Suppose a mouse (nocturnal) in constant dark has a FRP = 23 h and today, activity onset happens to occur at 6 in the morning local time. At approximately what CT will a light pulse fall if the lights are briefly turned on at noon today?
A) Impossible to tell
b) CT0
C) CT12
D) CT18
E) CT6
Consider the same mouse (FRP = 23 h, activity onset today at 6 am). If you wanted it to begin activity at 6 am tomorrow (same as today) it would need to get a light pulse that produced a _________. This would happen if the light pulse was scheduled to occur at _________.
A)1h delay; CT12
B) 1h advance; CT2
C) No advance or delay; CT6
1H advance; CT12
1h delay; CT2
Explanation / Answer
The correct option is (b) CT0
The correct option is 1 h advance; CT12
