How does your brain anticipate future events? Researchers explain that our brains learn how to predict future occurrences through patterns and this process is called “anticipatory timing.” but how actually does it work?
Researchers from the University of California, Berkeley conducted a new study which says that the human brain counts on two distinct ways while predicting an occurrence.
The team explains that one system is responsible to anticipate future events considering our past experiences, while the second system identifies rhythmic patterns.
In the latest study, the researchers included people with either Parkinson’s disease or cerebellar degeneration. Their findings are now published in the journal PNAS.
The investigators tested how people used temporal cues to complete different tests. The participants were asked to give responses to different series of colored squares. In the first test, the researchers flashed out the colored squares at a rhythmic pace, while during the second exercise, they were succeeded in a different pattern.
The researchers found that people with Parkinson’s disease responded better to the complex pattern test, while those with cerebellar degeneration tended to perform better on the rhythmic pattern exercise.
Senior study author Prof. Richard Ivry explains: “We show that patients with cerebellar degeneration are impaired in using nonrhythmic temporal cues while patients with basal ganglia degeneration associated with Parkinson’s disease are impaired in using rhythmic cues.”
The research helped the team to observe which brain regions were associated with which “anticipatory timing process”
