(a) Schematic of go/no-go tone-in-noise detection task. Licking responses to target tones were rewarded, while responses to narrowband noise distractors were penalized with a timeout. Target tone …
Cumulative reaction time histogram for each animal and target sound across all behavior sessions. Color indicates sound identity. Animals were rewarded for responses to all sounds except the catch.
(a) Example peristimulus time histogram (PSTH) responses from a single recording site in A1. Heatmap color in each row indicates the PSTH amplitude of one neuron. Dashed lines indicate sound …
Left hemisphere from one animal. Each marker indicates the anatomical location of a single electrode penetration. Color indicates the average best frequency (BF) of neurons recorded at each location …
(a) Example peristimulus time histogram (PSTH) responses from a single recording site in dPEG. Heatmap color in each row indicates the PSTH amplitude of one neuron. Dashed lines indicate sound …
Example peristimulus time histogram (PSTH) responses from all recording sites in A1. Each group of six panels corresponds to a single recording site, as in Figure 2. Heatmap color in each row of …
Example peristimulus time histogram (PSTH) responses from all recording sites in dPEG. Each group of six panels corresponds to a single recording site, as in Figure 2. Heatmap color in each row of …
(a) Left: Representative A1 population activity during passive listening projected into a two-dimensional space optimized for discriminating target versus catch responses. Each dot indicates the …
(a) Top: Histogram of pupil size across all experiments (n=39 sessions, n=4 animals) during active (orange) and passive (blue) trials. Pupil size is normalized to the max pupil size observed within …
Same as in Figure 3, without first correcting for pupil-indexed arousal explainable variance (i.e. decoding stimulus identity from raw neural activity, without controlling for global arousal). (a) …
(a) Scatter plot compares neural Δd-prime (active minus passive) for all tone-in-noise target vs. catch noise combinations against the corresponding behavioral d-prime for that target vs. catch …
(a) Mean choice probability on hit vs. miss trials across all A1 experiments, split by target stimulus signal-to-noise ratio (SNR). Gray shading represents the time when the target sound stimulus is …
(a) Schematic of population response over many trials to a catch stimulus (gray) and target stimulus (red), projected into a low-dimensional space. Dashed line indicates the sensory discrimination …
Population metrics extracted from factor analysis model fit. Models were fit to the catch stimulus only to control for variability due to stimulus identity. P=passive, A=active. (a) Loading …
(a) Mean Δd-prime across all target vs. target and target vs. catch stimulus pairs for each factor analysis based simulation: Null model, gain only model, independent variance model, and shared …
