Population decoding of predicted source direction.

<p>(A) Example model population activities plotted together with the true source direction (pink), the Bayesian prediction direction (green) and the PV estimate (blue). The color map codes for firing rate with white and black indicating high and low firing rates, respectively. (B) RMS error between the Bayesian prediction and the PV estimate averaged over one-second duration stimuli at the given initial direction and angular velocity. The values in gray indicate stimulus conditions where the RMS error was less than 3 deg. (C) The RMS error is highly correlated with the fraction of time the predicted source direction is behind the head. This occurs because all preferred directions are in the frontal hemisphere. (D) RMS error between the Bayesian prediction and the PV estimate for deterministic neurons and Poisson neurons. The solid line is the identity line.
