O'Keefe (1991) has proposed that spatial information in rats might be represented as phasors: phase and amplitude of a sine wave encoding angle and distance to a landmark. We describe computer simulations showing that operations on phasors can be e ciently realized by arrays of spiking neurons that re-code the temporal dimension of the sine wave spatially.(More)
We describe a theoretical model of spatial representation in cortex, including computer simulations, that is compatible with data from single neuron recordings. Our proposed architecture, called a sinusoidal array, encodes a polar vector ~v = (r; ) as distributed activity across a neuronal population. We demonstrate how sinusoidal arrays might be used for(More)
