The Dhaka Times Desk Can you see anything in the dark? It is normal not to be able to see anything far in pitch black night. But scientists say the brain can see even in the dark.
No matter how pitch black or dark, most people can at least see their own hand movements. In that case, the brain plays the best role of the eye. Such information has been given in a study of the University of Rochester, New York.
The researchers said that in the absence of all kinds of light, where the eyes are inactive, the brain becomes active in seeing.
Neuroscientists and psychologists have discovered that the mind can perceive limb movements even in complete darkness. Researchers believe that 50 percent of people see in the dark this way. Although seeing is done by the brain, people think they are seeing with their eyes. But actually it is the brain that does the whole job.
Duje Tadin, professor of brain and cognitive science at the University of Rochester, said that the answer to whether we can see in the dark comes out, it is not possible to see in the dark using the same eyes as the normal eye. Research shows that our body movements send a kind of sensory signal to the brain, which simultaneously creates a sense of normal vision in the brain. As a result, we see without seeing. This is done by the brain. The paper was published in the journal Psychological Science. Reference: The Indian Express.
