A quarter-century ago visual neuroscientists had little information about the number and
organization of retinotopic maps in human visual cortex. The advent of functional magnetic …

The cortex is a massively recurrent network, characterized by feedforward and feedback
connections between brain areas as well as lateral connections within an area …

Humans are capable of generating extraordinarily diverse articulatory movement
combinations to produce meaningful speech. This ability to orchestrate specific phonetic …

The visual processing of behaviorally relevant stimuli is enhanced through top-down
attentional feedback. One possibility is that feedback targets early visual areas first and the …

Attention is a critical component of perception. However, the mechanisms by which attention
modulates neuronal communication to guide behaviour are poorly understood. To elucidate …

Spatial attention enhances our ability to detect stimuli at restricted regions of the visual field.
This enhancement is thought to depend on the difficulty of the task being performed, but the …

The ultimate goal of neuroscience research is to understand the operating mechanism of the
human brain and to exploit this understanding to devise methods for repair when it …

Female mammals experience cyclical changes in sexual receptivity known as the estrus
cycle. Little is known about how estrus affects the cortex, although alterations in sensation …

fMRI is a tool to study brain function noninvasively that can reliably identify sites of neural
involvement for a given task. However, to what extent can fMRI signals be related to …

Much has been learned over the past 25 years about how attention influences neuronal
responses to stimuli in the visual cortex of monkeys and humans. The most recent studies …
