Fig 6. Modulation of OT activity by stimulus reliability.
(A,B) Average KL divergence (A) and performance of different estimators of uncertainty (B) from the population activity generated by the model of Saberi et al. [17]. Same conventions as in Fig 3B and Fig 5, respectively. Because this population is not a linear PPC, reconstruction of the uncertainty through linear decoding fails in this example, leading to negative R-square. The corresponding curve was thus removed. (C-F) ITD tuning curves of our OT model for different stimuli. (C) Original stimulus. Tuning curve replotted from Fig 4C-top. (D) Shorter stimulus duration, 5msec vs. 10msec for the original stimulus. (E) Low-passed filtered stimulus. (F) High-pass filtered stimulus. (G-J) Same as (C-F) but for the model of Saberi et al. [17].
