Egocentric and allocentric neural mechanisms for representing the body

摘要

Infants' ability to orient their actions in space improves dramatically after their sixth month. Recent developmental studies speculate that this enhancement of spatial memory relies on two mechanisms that evolve separately during the first year shifting from an egocentric representation of the body to an allocentric one. We present two different mechanisms of neural networks to represent on the one hand the body-centered information which correlates the body signals and on the other the allocentric body schema that remaps dynamically the position of the limbs and the muscles lengths.
