The paper isolates task engagement and arousal effects in auditory cortex and midbrain using single-unit recordings and generalized linear modeling, finding distinct neural population responses to each.

The paper investigates how arousal affects neural coding of natural sounds in auditory cortex by analyzing changes in response magnitude and noise correlations.

The paper examines how pupil size fluctuations affect neural activity and selectivity in auditory cortex, finding increased excitability but stable stimulus selectivity.

The paper develops a model of spectral adaptation in auditory cortex that incorporates short-term synaptic plasticity to better predict neural responses to natural sounds than standard models.
