Human visual perception carves a scene at its physical joints, decomposing the world into
objects, which are selectively attended, tracked and predicted as we engage our …

The problem of consciousness continues to be a subject of great debate in cognitive
science. Synthesizing decades of research, The Conscious Brain advances a new theory of …

Closing the structure-function divide is more challenging in the brain than in any other
organ. For example, in early visual cortex, feedback projections to V1 can be quantified (eg,) …

How does the brain learn to recognize objects visually, and perform this difficult feat robustly
in the face of many sources of ambiguity and variability? We present a computational model …

Standard models of the visual object recognition pathway hold that a largely feedforward
process from the retina through inferotemporal cortex leads to object identification. A …

A striking example of the constructive nature of visual perception is how the human visual
system completes contours of occluded objects. To date, it is unclear whether perceptual …

We easily recover the causal properties of visual events, enabling us to understand and
predict changes in the physical world. We see a tennis racket hitting a ball and sense that it …

In mammals smooth retinotopic maps of the visual field are formed along the visual
processing pathway whereby the left visual field is represented in the right hemisphere and …

Prefrontal synthesis (PFS) is a component of constructive imagination. It is defined as the
process of mentally juxtaposing objects into novel combinations. For example, to …

Visual imagery–similar to visual perception–activates feature-specific and category-specific
visual areas. This is frequently observed in experiments where the instruction is to imagine …
