Speaker The reindeer has internal clock set by melatonin to synchronize their annual clock. But they tell the date but could not tell the time of a day.

Our brain has two internal clocks to help us always keep accurate time.
3. 03:11.71
A part of brain called Hippocampus could measure the passage of time. An experiment with rats shows that they can not tell the difference between similar intervals without Hippocampus.
4. 05:11.37
Striatum and Hippocampus are competing with each other. Damaging striatum will lead to the problem of processing time.

New drugs are developed to overcome the Jet lag and reset our biological clock. Four discoveries suggest the the possibilities.

The blind cavefish could control their internal clock by controlling the metabolism in the darkness.

The cave-dwelling fish does’t show the same behaviour. More researchers are interested in those animals that don’t have the circadian rhythm.
Obstacle 06:46.70 As we grow older, we find the time passes more quickly. Experiments are made by researchers to prove that time speeds up by fewer memory events. Besides, young people feel time goes slowly while old people use swift metaphor to describe the passage of time. The studies draw two conclusions that time pressure contributes to our perception of time and time passage is also cross-cultural. Psychologists put forth 5 theories to explain why we feel time passes quickly as we grow up. |
