Neural and behavioral investigations into timbre perception

Stephen M. Town, Jennifer K. Bizley
2013 Frontiers in Systems Neuroscience  
We also consider the perception of timbre by animals, both in the case of human vowels and non-human vocalizations.  ...  We then explore the neural representation of timbre, first within the peripheral auditory system and later at the level of the auditory cortex.  ...  HOW DO SINGLE NEURONS IN AUDITORY CORTEX ENCODE TIMBRE? What about the single neuron computations that underlie timbre perception?  ...

Multiplexed and Robust Representations of Sound Features in Auditory Cortex

K. M. M. Walker, J. K. Bizley, A. J. King, J. W. H. Schnupp
2011 Journal of Neuroscience  
In this study, we investigate whether neurons in both core and belt areas of ferret auditory cortex can robustly represent the pitch, formant frequencies, or azimuthal location of artificial vowel sounds  ...  Finally, we observed that formant information is encoded in cortex earlier than pitch information, and we show that this time course matches ferrets' behavioral reaction time differences on a change detection  ...  earlier for timbre than for pitch cues in auditory cortex.  ...
