The Role of Spike Timing in the Coding of Stimulus Location in Rat Somatosensory Cortex
TLDR
It is demonstrated that, in the whisker representation of rat cortex, precise spike timing of single neurons increases the information transmitted about stimulus location by 44%, compared to that transmitted only by the total number of spikes.About:

Rapid Neural Coding in the Retina with Relative Spike Latencies
Tim Gollisch,Markus Meister +1 more
TL;DR: It is reported that certain retinal ganglion cells encode the spatial structure of a briefly presented image in the relative timing of their first spikes, which allows the retina to rapidly and reliably transmit new spatial information with the very first spikes emitted by a neural population.

Extracting information from neuronal populations: information theory and decoding approaches.
TL;DR: To further understand how the brain processes information, it is important to shift from a single-neuron, multiple-trial framework to multiple-NEuron, single-trial methodologies.

TL;DR: This final installment of the paper considers the case where the signals or the messages or both are continuously variable, in contrast with the discrete nature assumed until now.

Speed of processing in the human visual system.
TL;DR: The visual processing needed to perform this highly demanding task can be achieved in under 150 ms, and ERP analysis revealed a frontal negativity specific to no-go trials that develops roughly 150 ms after stimulus onset.

Spikes: Exploring the Neural Code
TL;DR: Spikes provides a self-contained review of relevant concepts in information theory and statistical decision theory about the representation of sensory signals in neural spike trains and a quantitative framework is used to pose precise questions about the structure of the neural code.

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
Information theory and neural coding.
TL;DR: This approach shows that dynamic stimuli can be encoded efficiently by single neurons and that each spike contributes to information transmission, and argues that the data obtained so far do not suggest a temporal code, in which the placement of spikes relative to each other yields additional information.
