Rapid task-related plasticity of spectrotemporal receptive fields in primary auditory cortex
Investigation of the hypothesis that task performance can rapidly and adaptively reshape cortical receptive field properties in accord with specific task demands and salient sensory cues found that attending to a specific target frequency during the detection task consistently induced localized facilitative changes in STRF shape.

Differential Dynamic Plasticity of A1 Receptive Fields during Multiple Spectral Tasks
A distinct pattern of STRF change is found in ferret primary auditory cortex, characterized by an expected selective enhancement at target tone frequency but also by an equally selective depression at reference tone frequency.

It is demonstrated that either a simplified model of synaptic depression and facilitation, and/or a cortical network of thalamic excitation and cortical inhibition can account for major trends in the observed findings.
Music in Our Ears: The Biological Bases of Musical Timbre Perception
The study demonstrates that joint spectro-temporal features, such as those observed in the mammalian primary auditory cortex, are critical to provide the rich-enough representation necessary to account for perceptual judgments of timbre by human listeners, as well as recognition of musical instruments.
