Journal ArticleDOI
The analysis of visual motion: a comparison of neuronal and psychophysical performance.
TL;DR: The ability of psychophysical observers and single cortical neurons to discriminate weak motion signals in a stochastic visual display is compared and psychophysical decisions in this task are likely to be based upon a relatively small number of neural signals.
Journal ArticleDOI
Reliability of spike timing in neocortical neurons
TL;DR: Data suggest a low intrinsic noise level in spike generation, which could allow cortical neurons to accurately transform synaptic input into spike sequences, supporting a possible role for spike timing in the processing of cortical information by the neocortex.

TL;DR: In this article, the authors measured neural variability in 13 extracellularly recorded datasets and one intra-cellularly recorded dataset from seven areas spanning the four cortical lobes in monkeys and cats and found that stimulus onset caused a decline in neural variability.
Journal ArticleDOI
The statistical reliability of signals in single neurons in cat and monkey visual cortex.
TL;DR: The variability of the discharge of visual cortical neurons in cats and macaque monkeys limits the reliability with which such neurons can relay signals about weak visual stimuli.
Journal ArticleDOI
A computational analysis of the relationship between neuronal and behavioral responses to visual motion
TL;DR: A model that pools neuronal responses drawn from the authors' physiological data set and compares average responses in different pools to produce psychophysical decisions is developed, suggesting that monkeys base near-threshold psychophysical judgments on signals carried by populations of weakly interacting neurons.
