Human and non-human primates can learn an astonishing variety of novel behaviours that could not have been directly anticipated by evolution. This ability to cope with new situations is due to the “pre-adapted” nature of the primate brain, says a study.

The brain anticipates all of the new situations that it may encounter in a lifetime by creating a special kind of neural network, the study said.
The findings appeared in the journal PLOS Computational Biology.

For the study, researchers from French National Institute of Health and Medical Research (Inserm) investigated one of the most noteworthy properties of primate behavior, its diversity and adaptability.

This study showed that our seemingly miraculous pre-adaptation comes from connections between neurons that form recurrent loops where inputs can rebound and mix in the network, like waves in a pond, thus called “reservoir” computing.
