Abstract
O'Keefe (1991) has proposed that spatial information in rats might be represented as phasors: phase and amplitude of a sine wave encoding an gle and distance to a landmark. We describe computer simulations showi ng that operations on phasors can be efficiently realized by arrays of spiking neurons that recode the temporal dimension of the sine wave s patially. Some cells in motor and parietal cortex exhibit response pro perties compatible with this proposal.
