A team of German scientists that the human brain predict what you will see his eyes in the vicinity of familiar.

The researchers, from the Max Planck Institute for Research on Human Cognitive and Brain in Frankfurt, that the brain does not make an extra effort was dramatically unless monitored eye element unexpectedly.

Instead, scientists that the brain is less when you make an effort to look at something familiar, indicating that the «expected» What rights will see, according to the study published by the magazine «Neuroscience».

A team of scientists, led by Dr. Ariane Aleinik, that the primary visual cortex of human brain recognizes objects expected more easily than things that did not expect to see. The study included people who look at the sample points are separated by a white rectangular forms on a regular basis. And use the magnetic resonance device effectively to monitor brain activity in the visual cortex.

And when she appeared in the form of rectangular shapes different from the usual model, the visual cortex has stepped up its efforts to get to know this thing is not expected. The scientists said that this result implies that the human brain make the effort less «see» what is expected to see.

These include the study is important, namely, that visual perception depends on the expectation effectively. This contrasts with the vision of the classic notion that visual perception stems primarily from the waterfall of the least effective responses to visual signals that spread through the brain.
