Human Brain Anticipates Stimuli Prior To Experiencing Them, Study Shows

The brain is very efficient at processing various stimuli

The human brain is very complex in that it computes everything that it senses within milliseconds. But the real deal here is that brains can determine a stimulus much faster if it is something that is to be expected. The real stimuli are only being determined after several milliseconds.

According to the scientists from Max Planck Institute for Brain Research in Frankfurt, their tests have showed that people that already know what will happen or are expecting what is going to happen can process the stimuli much faster than when those stimuli are unexpected. The brain calculates what is going to happen before the actual thing really happens, making it possible for people to adjust to reality.

In relation to their study, the timing of the EEG perception varies on every situation that stimulates the brain. Those stimuli that are expected shows 100 milliseconds earlier conscious perceptions compared to those that are unexpected.

The study also concludes that the brain is flexible and that it does not rigidly process the stimuli. The processing of the brain with conscious perception happens earlier if there is an established expectation of what is going to happen. It takes longer if there are no earlier stimuli that can become its basis for the prediction.

This only proves that the brain does not rely on every stimulus that it encounters, but rather it uses them to make predictions and make it easier for people to perceive.
