Here's How We Take Aim
Neuroscientists have decoded brain maps to discover how we take aim, according to a new study.
The study shows that different regions of the brain help visually locate objects relative to one's own body (self-centered or egocentric) and those relative to external visual landmarks (world-centered or allocentric).
"The current study shows how the brain encodes allocentric and egocentric space in different ways during activities that involve manual aiming," explained Distinguished Research Professor Doug Crawford, in the Department of Psychology, in the press release. "Take tennis for example. Allocentric brain areas could help aim the ball toward the opponent's weak side of play, whereas the egocentric areas would make sure your muscles return the serve in the right direction."
The study findings will help healthcare providers to develop therapeutic treatment for patients with brain damage in these two areas.
"As a neurologist, I am excited by the finding because it provides clues for doctors and therapists how they might design different therapeutic approaches," said Ying Chen, lead researcher and PhD candidate in the School of Kinesiology and Health Science, in the press release.
Findings of the study have been published in the Journal of Neuroscience.
