2 Figure 1 Schematic of Stimulus Selection Task and Hypothetical Population Response (A) Rat in behavioral apparatus on a trial in which a white noise stimulus and a low-pitch warble are played from the left speaker. Because this is a “spatial” context, the correct response is to go to the left reward port. (B) Same as (A) except that the trial is presented in the “pitch” context, so the low-pitch warble indicates that the correct response is the right reward port. (C) Hypothetical population responses to the stimuli in (A) presented in the “spatial” context. A subset of neurons (colored red) has elevated firing rates. (D) Hypothetical population response to the same stimuli, this time presented in the “pitch” context. A different subset of neurons is active compared with the “spatial” context, shown in (C).
