摘要

Relationships among cortical feature maps may influence the ability of the early visual system to sense the orientation and position of a line stimulus. Several combinations of orientation maps and visuotopic maps were studied. The neurons were characterized by their receptive fields in the space of stimulus parameters and a stochastical response. Fisher information was calculated for each stimulus parameter and the average bound on the variance was used as the measure of error of parameter estimation. We conclude that the distortions of the visuotopic map suggested by the experimentally measured statistics result in decreased accuracy of the parameter estimation.
