Can the brain "predict" the future?

Scientists at the University of California in Berkeley (United States) have discovered that the brain uses two 'clocks' to make temporary predictions that are found in different parts of that organ.

This study suggests that "there are two different ways" in which those brain systems "allow us not only to exist", but also "actively anticipate the future," explained the specialist who led this research, Assaf Breska, and informs him Science Daily portal.

Thus, one of those internal mechanisms is based on the experiences of the past and is connected to the cerebellum, while the other depends on the rhythm and is connected to the basal ganglia.

The rhythm-based system "is sensitive to periodic events, such as what is innate to speech and music." On the other hand, "the interval system provides a more general anticipatory capacity, sensitive to temporal regularities even in the absence of a rhythmic signal."

An example of the first situation would be to move the body before it sounds the first note of the music we expect, while the second one would be illustrated by the fact that stepping on the accelerator pedal a fraction of a second before switching the light at the traffic light .

These findings would challenge the idea that a single brain system handles all our temporary needs and would suggest that if one of those 'neural clocks' fails, the other could take over their tasks.
