Interaction between tuning curve and prior in population tuning. A Bias map for combinations of tuning curve width and prior sharpness. Negative bias means that perception of a near-/ba/stimulus was biased toward/ba/, namely categorical perception. Three inset plots on ordinate and abscissa show the cases of the lowest/median/highest concentration parameters of tuning curve and prior peak, respectively. B Discrimination difference map. Negative number indicates that between-phoneme condition outperformed near-/ba/condition. C Tuning curves of population neurons that was marked as green squares in A, B. Location of tuning centers were marked as dots for 60 neurons, and tuning curves of 30 out of those 60 neurons were drawn below
