Scientists Claim to Track Brain Activities during Dreaming

Scientists Claim to Track Brain Activities during DreamingA team of scientists, in collaboration with experts from the Charite hospital in Berlin, has claimed to estimate the brain's content successfully for the first time. Simultaneously, they examined several complex brain activities executing at the time of dreaming.

The scientists have carried out the research with the help of subjects who acquire good consciousness, even while dreaming, along with potential to modify the content of their dream. Such people are popularly known as lucid dreamers. During the study, the experts observed that the brain activity was almost identical to the dreamed motion.

At the time of experiment, the experts directed lucid dreamers to remain aware about their dreaming and exposed them to a device named magnetic resonance imaging (MRI). Afterwards, they questioned the subjects to dream about tightening their right hand fist and then left fist for about 10 seconds.

Experts have successfully identified and visualised the accurate spatial location of brain activity among sleeping subjects with the help of applications such as functional magnetic resonance imaging.

While briefing the study findings, the lead study author, an expert from the Max Planck Institute for Psychiatry, Michael Czisch, who also led the study, said: "Our dreams are therefore not a 'sleep cinema' in which we merely observe an event passively, but involve activity in the regions of the brain that are relevant to the dream content".

Further, experts notified that sensorimotor cortex of the brain has a region that plays a significant role to execute all those movements that are believed to be spurring during dreaming.

On the other hand, researcher Martin Dresler claimed that the excellent blend of sleep EEGs, imaging techniques as well as lucid dreamers have enabled the experts to measure the brain activities.
