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 …

Encoding stimulus information by spike numbers and mean response time in primary auditory cortex
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
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
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
Fluctuations in the amplitude envelope of complex sounds provide critical cues for hearing,
particularly for speech and animal vocalizations. Responses to amplitude modulation (AM) …
