Nature and precision of temporal coding in visual cortex: a metric-space analysis.
1. We recorded single-unit and multi-unit activity in response to transient presentation of texture and grating patterns at 25 sites within the parafoveal representation of V1, V2, and V3 of two… Expand
Metric-space analysis of spike trains: theory, algorithms and application
We present the mathematical basis of a new approach to the analysis of temporal coding. Expand
The effect of contrast on the transfer properties of cat retinal ganglion cells.
1. Variation in stimulus contrast produces a marked effect on the dynamics of the cat retina. This contrast effect was investigated by measurement of the responses of X and Y ganglion cells. The… Expand

1. The dynamics of the centre mechanism of individual cat X retinal ganglion cells is investigated. The visual stimuli consist of temporal contrast modulation of stationary patterns. In order to… Expand
Independent and Redundant Information in Nearby Cortical Neurons
In the primary visual cortex (V1), nearby neurons are tuned to similar stimulus features, and, depending on the manner and time scale over which neuronal signals are analyzed, the resulting… Expand

Temporal coding of contrast in primary visual cortex: when, what, and why.
How do neurons in the primary visual cortex (V1) encode the contrast of a visual stimulus? In this paper, the information that V1 responses convey about the contrast of static visual stimuli is… Expand
A method of nonlinear analysis in the frequency domain.
A method is developed for the analysis of nonlinear biological systems based on an input temporal signal that consists of a sum of a large number of sinusoids. Nonlinear properties of the system are… Expand
A new statistic for steady-state evoked potentials.
Steady-state evoked potentials are often characterized by the amplitude and phase of the Fourier component at one or more frequencies of interest. We introduce a new statistic for the evaluation of… Expand
The use of m-sequences in the analysis of visual neurons: linear receptive field properties.
We have used Sutter's (1987) spatiotemporal m-sequence method to map the receptive fields of neurons in the visual system of the cat. The stimulus consisted of a grid of 16 x 16 square regions, each… Expand
