A widely discussed hypothesis in neuroscience is that transiently active ensembles of
neurons, known as" cell assemblies," underlie numerous operations of the brain, from …

Most of our knowledge about the functional organization of neuronal systems is based on
the analysis of the firing patterns of individual neurons that have been recorded one by one …

Memory is fleeting. New material rapidly obliterates previous material. How, then, can the
brain deal successfully with the continual deluge of linguistic input? We argue that, to deal …

The medieval curriculum comprised seven liberal arts, divided into the lower-level trivium
(grammar, logic, and rhetoric) and the upper-level quadrivium (geometry, astronomy …

We describe a model of visual processing in which feedback connections from a higher-to a
lower-order visual cortical area carry predictions of lower-level neural activities, whereas the …

Visual processing in cortex is classically modeled as a hierarchy of increasingly
sophisticated representations, naturally extending the model of simple to complex cells of …

Two new algorithms for computer recognition of human faces, one based on the
computation of a set of geometrical features, such as nose width and length, mouth position …

The problem of the approximation of nonlinear mapping,(especially continuous mappings) is
considered. Regularization theory and a theoretical framework for approximation (based on …

Here we review recent findings that reveal the functional properties of extra-striate regions in
the human visual cortex that are involved in the representation and perception of objects …

We perceive the shapes and material properties of objects quickly and reliably despite the
complexity and objective ambiguities of natural images. Typical images are highly complex …
