Neural space representation in a moving frame

Spatial positions of objects are represented by clouds of activation´ in a neural grid. In a moving frame these moving clouds provide a stable representation of objects in the inertial coordinate system. Relative motion of the activation pattern is realized by creation and detection of activity along three axes of the neural grid. First results are reported from simulations of a system with one rotatory and two translatory degrees of freedom. It is easy to extend the system to six degrees of freedom without changing the theory. Biological aspects of the mechanism are discussed
