Rate, not selectivity, determines neuronal population coding accuracy in auditory cortex

W Sun, DL Barbour - PLoS biology, 2017 - journals.plos.org
The notion that neurons with higher selectivity carry more information about external sensory
inputs is widely accepted in neuroscience. High-selectivity neurons respond to a narrow …

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 …

Encoding stimulus information by spike numbers and mean response time in primary auditory cortex

I Nelken, G Chechik, TD Mrsic-Flogel, AJ King… - Journal of computational …, 2005 - Springer
Neurons can transmit information about sensory stimuli via their firing rate, spike latency, or
by the occurrence of complex spike patterns. Identifying which aspects of the neural …

Neural codes formed by small and temporally precise populations in auditory cortex

RAA Ince, S Panzeri, C Kayser - Journal of Neuroscience, 2013 - Soc Neuroscience
The encoding of sensory information by populations of cortical neurons forms the basis for
perception but remains poorly understood. To understand the constraints of cortical …

The contribution of spike threshold to acoustic feature selectivity, spike information content, and information throughput

MA Escabí, R Nassiri, LM Miller… - Journal of …, 2005 - Soc Neuroscience
Hypotheses of sensory coding range from the notion of nonlinear “feature detectors” to linear
rate coding strategies. Here, we report that auditory neurons exhibit a novel trade-off in the …

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) …

Stable encoding of sounds over a broad range of statistical parameters in the auditory cortex

JM Blackwell, TO Taillefumier, RG Natan… - European Journal of …, 2016 - Wiley Online Library
Natural auditory scenes possess highly structured statistical regularities, which are dictated
by the physics of sound production in nature, such as scale‐invariance. We recently …

Understanding neural population coding: Information theoretic insights from the auditory system

A Onken, PPCR Karunasekara… - Advances in …, 2014 - Wiley Online Library
In recent years, our research in computational neuroscience has focused on understanding
how populations of neurons encode naturalistic stimuli. In particular, we focused on how …

Information content of auditory cortical responses to time-varying acoustic stimuli

T Lu, X Wang - Journal of neurophysiology, 2004 - journals.physiology.org
The present study explores the issue of cortical coding by spike count and timing using
statistical and information theoretic methods. We have shown in previous studies that …

State-dependent geometry of population activity in rat auditory cortex

D Kobak, JL Pardo-Vazquez, M Valente, CK Machens… - Elife, 2019 - elifesciences.org
The accuracy of the neural code depends on the relative embedding of signal and noise in
the activity of neural populations. Despite a wealth of theoretical work on population codes …
