A redundant cortical code for speech envelope

KB Penikis, DH Sanes - Journal of Neuroscience, 2023 - Soc Neuroscience
Animal communication sounds exhibit complex temporal structure because of the amplitude
fluctuations that comprise the sound envelope. In human speech, envelope modulations …

Temporally precise population coding of dynamic sounds by auditory cortex

JD Downer, J Bigelow, MJ Runfeldt… - Journal of …, 2021 - journals.physiology.org
Fluctuations in the amplitude envelope of complex sounds provide critical cues for hearing,
particularly for speech and animal vocalizations. Responses to amplitude modulation (AM) …

[HTML][HTML] The tracking of speech envelope in the human cortex

J Kubanek, P Brunner, A Gunduz, D Poeppel… - PloS one, 2013 - journals.plos.org
Humans are highly adept at processing speech. Recently, it has been shown that slow
temporal information in speech (ie, the envelope of speech) is critical for speech …

Right-hemisphere auditory cortex is dominant for coding syllable patterns in speech

DA Abrams, T Nicol, S Zecker… - Journal of Neuroscience, 2008 - Soc Neuroscience
Cortical analysis of speech has long been considered the domain of left-hemisphere
auditory areas. A recent hypothesis poses that cortical processing of acoustic signals …

Selective effects of arousal on population coding of natural sounds in auditory cortex

CR Heller, ZP Schwartz, D Saderi, SV David - BioRxiv, 2020 - biorxiv.org
The ability to discriminate between complex natural sounds is critical for survival. Changes
in arousal and other aspects of behavioral state can impact the accuracy of sensory coding …

Speech coding in the brain: representation of vowel formants by midbrain neurons tuned to sound fluctuations

LH Carney, T Li, JM McDonough - Eneuro, 2015 - eneuro.org
Current models for neural coding of vowels are typically based on linear descriptions of the
auditory periphery, and fail at high sound levels and in background noise. These models …

Plasticity of temporal pattern codes for vocalization stimuli in primary auditory cortex

JWH Schnupp, TM Hall, RF Kokelaar… - Journal of …, 2006 - Soc Neuroscience
It has been suggested that “call-selective” neurons may play an important role in the
encoding of vocalizations in primary auditory cortex (A1). For example, marmoset A1 …

Hierarchical differences in population coding within auditory cortex

JD Downer, M Niwa, ML Sutter - Journal of …, 2017 - journals.physiology.org
Most models of auditory cortical (AC) population coding have focused on primary auditory
cortex (A1). Thus our understanding of how neural coding for sounds progresses along the …

[HTML][HTML] Selective and efficient neural coding of communication signals depends on early acoustic and social environment

N Amin, M Gastpar, FE Theunissen - PLoS One, 2013 - journals.plos.org
Previous research has shown that postnatal exposure to simple, synthetic sounds can affect
the sound representation in the auditory cortex as reflected by changes in the tonotopic map …

Efficient encoding of vocalizations in the auditory midbrain

LA Holmstrom, LBM Eeuwes, PD Roberts… - Journal of …, 2010 - Soc Neuroscience
An important question in sensory neuroscience is what coding strategies and mechanisms
are used by the brain to detect and discriminate among behaviorally relevant stimuli. There …
