FIG. 3.

Directional acuity for presentations of broadband noise in the inter-aural horizontal plane. A Licking behavior of six mice before stimulus presentations (dashed lines) and during stimulus presentations (solid lines). Bin counts indicate the presence of licking in 20 contiguous 20-ms intervals. B Psychometric functions relating hit and false alarm rates to the angular separation between safe and warning speakers. Response rates were calculated by applying individualized criterion scores to the bin counts in A. C Discrimination performance (d′) derived from the hit and false alarms rates in B.
