The dependence of error in identifying the true OI on neural noise and stimulus sampling. On the Y axis of all plots is the average deviation between the “true” OI (or DI) and the “best guess” of OI (or DI) based on the empirical 1-CirVar (or 1-DirCirVar). (A) Dependence of error on single trial noise as a percentage of the maximum response rate to the preferred direction. (B) Dependence of error on the number of trials. More trials offer modest improvements in average accuracy. (C) Dependence of error on number of angle steps. Additional angle steps offer a big improvement in estimating the amount of orientation or direction selectivity present. (D) Dependence of error for assorted numbers of trials and angle steps.
