Abstract

O'Keefe (1991) has proposed that spatial information in ratsmight be represented as phasors: phase and amplitude of a sine waveencoding angle and distance to a landmark. We describe computersimulations showing that operations on phasors can be efficientlyrealized by arrays of spiking neurons that recode the temporaldimension of the sine wave spatially. Some cells in motor andparietal cortex exhibit response properties compatible with thisproposal.
