Question

Which type of blind person tends to be wakeful in synchrony with sunlight,and why?​

Quizplus · Accepted Answer

People blind as a result of cortical damage can still synchronize to sunlight because their eyes can still detect light, which is processed by the brain area controlling circadian rhythms, even though they cannot consciously see. This synchronization is not due to the gravitational pull of the sun or light striking the skin, but rather the ability of the eyes to detect light and send signals to the brain.
