Can the brain "predict" the future?

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

This study suggests that "there are two different ways" in which these brain systems "allow us to not only exist," but also "actively anticipate the future," said Assaf Breska, a research specialist who reports the Scientific Portal daily.

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

The rhythm-based system "is sensitive to periodic events, such as what is inherent in speech and music." On the other hand, "the system of intervals provides a more general anticipation capability, 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 the first note of the music we are waiting for, and the second one would be depicted by pressing the accelerator pedal a fraction of a second before changing the light. .

These findings would challenge the idea that a single brain system deals with all of our temporal needs and would suggest that if one of those "neural clocks" fails, the other may take over.
