The method quantifies the posture and movement patterns of infants from lying supine until they master walking independently.

It helps in designing brain surgery and speeds up the direct cortical stimulation conducted during the surgery. This report describes how to perform speech cortical mapping reliably for preoperative evaluation and research.
