A team of neuroscientists at the Beth Israel Deaconess Medical Center has employed a new technique called “Lesion network mapping” to locate neuroanatomical origins of the perception of free will, a development that holds relevance beyond patients with brain injury.

The study, published in “The Proceedings of the National Academy of Sciences,” sheds light on some surprising links between brain regions and disorders, providing a better understanding of brain disorders including Parkinson’s disease, notes Scientific American.

The study also found that the lesions hampering the free will for movement fell within one of two distinct brain networks, and stimulating these sites altered free will perception in healthy research participants, writes Science Daily.
