The timbre model provides an efficient representation of processing in human auditory cortex via a compact model whose features are based on subjective ratings of timbre. ...doi:10.1016/j.neuroimage.2017.10.050 pmid:29080711 pmcid:PMC5747995 fatcat:kwbzgpq2qvc4fdbbxbhnbnhsha
In this article, the authors examine evidence that the auditory cortex is necessary for processing the pitch, timbre, and location of sounds, and document how neurons across multiple auditory cortical ... However, we still know surprisingly little about how neurons in the auditory brain, specifically the auditory cortex, might form representations of these perceptual characteristics from the information ...

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? ...doi:10.3389/fnsys.2013.00088 pmid:24312021 pmcid:PMC3826062 fatcat:e6ahxtlfcbdkbaqcv4ss3ebjta
Although indicating that neural encoding of pitch, location, and timbre cues is distributed across auditory cortex, significant differences in average neuronal sensitivity were observed across cortical ... We recorded responses to artificial vowels presented in virtual acoustic space to investigate the representations of pitch, timbre, and sound source azimuth in both core and belt areas of ferret auditory ... The lack of a single pitch center in ferret auditory cortex is supported by the results of imaging studies in ferrets and humans (Hall and Plack, 2008) . ...doi:10.1523/jneurosci.4755-08.2009 pmid:19228960 pmcid:PMC2663390 fatcat:zbp543bj5ranpkacbmxloxjpv4

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. ...doi:10.1523/jneurosci.2074-11.2011 pmid:21994373 pmcid:PMC3272412 fatcat:bf6ww46uobbfzj3n2hxknh6lry
