Widespread loss of cerebral connectivity is assumed to underlie the failure of brain mechanisms
that support communication and goal-directed behaviour following severe traumatic …

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 …

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 …

We present the mathematical basis of a new approach to the analysis of temporal coding.
The foundation of the approach is the construction of several families of novel distances (…

OBJECTIVE: To evaluate an integrated battery of preoperative functional magnetic resonance
imaging (fMRI) tasks developed to identify cortical areas associated with tactile, motor, …

Connectivity in the cortex is organized at multiple scales 1 , 2 , 3 , 4 , 5 , suggesting that
scale-dependent correlated activity is particularly important for understanding the behaviour of …

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 …

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 …

OBJECTIVE: To determine whether EEG spectral analysis could be used to demonstrate
awareness in patients with severe brain injury. METHODS: We recorded EEG from healthy …

We found a new class of two-dimensional random textures with identical third-order
statistics that can be effortlessly discriminated. Discrimination is based on local “granularity” …
