    Dept of Physiology, Anatomy and Genetics, Sherrington Building, University of Oxford, Parks Road, Oxford OX13PT, United Kingdom
    Hear Res 271:74-87. 2011
    ..These questions can begin to be addressed through a cooperation of investigative efforts across species and experimental techniques, and, critically, by examining the responses of single neurons in behaving animals...
  2. pmc Multiplexed and robust representations of sound features in auditory cortex
    Kerry M M Walker
    Department of Physiology, Anatomy and Genetics, University of Oxford, Oxford OX1 3PT, UK
    J Neurosci 31:14565-76. 2011
    ..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 task...

    Kerry M M Walker
    Department of Physiology, Aantomy and Genetics, University of Oxford, Parks Road, Oxford OX1 3PT, UK
    Curr Biol 21:R251-3. 2011
    ..A recent study shows that expectation about the timing of behaviorally-relevant sounds enhances the responses of neurons in the primary auditory cortex and improves the accuracy and speed with which animals respond to those sounds...
  4. pmc Interdependent encoding of pitch, timbre, and spatial location in auditory cortex
    Jennifer K Bizley
    Department of Physiology, Anatomy, and Genetics, University of Oxford, Oxford OX1 3PT, United Kingdom
    J Neurosci 29:2064-75. 2009
    ..Such nonlinearities were most prevalent in primary auditory cortex, although they tended to be small compared with stimulus main effects...

    Jennifer K Bizley
    Department of Physiology, Anatomy, and Genetics, University of Oxford, Oxford OX1 3PT, United Kingdom, and Robotics, Brain, and Cognitive Sciences Department, Italian Institute of Technology, 16163 Genova, Italy
    J Neurosci 30:5078-91. 2010
    ..Because trained animals can discriminate stimulus periodicity across different sound levels, this implies that ensemble codes are better suited to account for behavioral performance...

    Jennifer K Bizley
    Department of Physiology, Anatomy and Genetics, University of Oxford, Oxford OX1 3PT, UK
    Curr Biol 23:620-5. 2013
    ..Surprisingly, although the stimulus F0 was well represented at the onset of the target sound, neural activity throughout auditory cortex frequently predicted the reported pitch better than the target F0...

    Jennifer K Bizley
    Department of Physiology, Anatomy and Genetics, University of Oxford, Parks Road, Oxford OX1 3PT, United Kingdom
    J Acoust Soc Am 133:365-76. 2013
    ..These data indicate that ferrets show robust vowel discrimination behavior across a range of listening conditions and that this ability shares many similarities with human listeners...

    Neuroscientist 16:453-69. 2010
    ..Providing an explanation of the neural basis of feature invariance is thus one of the major challenges to sensory neuroscience obtaining the ultimate goal of understanding how neural firing patterns in the brain give rise to perception...

    Andrew J King
    Department of Physiology, Anatomy and Genetics, University of Oxford, Oxford, UK
    Biol Cybern 106:617-25. 2012
    ..We highlight some of the many open research questions that exist about the neural mechanisms that give rise to multisensory integration in auditory cortex, which should be addressed in future experimental and theoretical studies...

    J Acoust Soc Am 126:1321-35. 2009
    ..These results suggest that while non-human animals can be trained to label complex sounds as high or low in pitch, this task may be much more difficult for animals than simply detecting a frequency change...
