Increased Activity in Human Visual Cortex during Directed Attention in the Absence of Visual Stimulation
TLDR
The increased activity in visual cortex in the absence of visual stimulation may reflect a top-down bias of neural signals in favor of the attended location, which derives from a fronto-parietal network. Expand
Functional MRI evidence for adult motor cortex plasticity during motor skill learning
TLDR
A slowly evolving, long-term, experience-dependent reorganization of the adult Ml is suggested, which may underlie the acquisition and retention of the motor skill. Expand
Mechanisms of visual attention in the human cortex.
TLDR
Functional brain imaging studies reveal that, both in the absence and in the presence of visual stimulation, biasing signals due to selective attention can modulate neural activity in visual cortex in several ways. Expand
The acquisition of skilled motor performance: fast and slow experience-driven changes in primary motor cortex.
TLDR
It is shown that a few minutes of daily practice on a sequential finger opposition task can be sufficient to trigger performance gains that require time to become evident, and proposed that skilled motor performance is acquired in several stages: "fast" learning, an initial, within-session improvement phase, followed by a period of consolidation of several hours duration, and then "slow" learnings, consisting of delayed, incremental gains in performance emerging after continued practice.

Neural processing of emotional faces requires attention
TLDR
Functional magnetic resonance imaging was used to measure activation in regions that responded differentially to faces with emotional expressions compared with neutral faces, and the modulation of these responses by attention was measured, using a competing task with a high attentional load. Expand
Multiple visual areas in the caudal superior temporal sulcus of the macaque
TLDR
Several visual areas were distinguished within the caudal STS, based on differences in their visuotopic organization, neuronal properties, receptive field size, myeloarchitecture, and pattern of connections with MT. Expand
An area specialized for spatial working memory in human frontal cortex.
TLDR
Using functional magnetic resonance imaging in humans, an area in the superior frontal sulcus was identified that is specialized for spatial working memory. Expand
A general mechanism for perceptual decision-making in the human brain
TLDR
Functional magnetic resonance imaging and a categorization task show that even for complex object categories, the comparison of the outputs of different pools of selectively tuned neurons could be a general mechanism by which the human brain computes perceptual decisions. Expand
Neural correlates of category-specific knowledge
TLDR
It is found that naming pictures of animals and tools was associated with bilateral activation of the ventral temporal lobes and Broca's area, and the brain regions active during object identification are dependent, in part, on the intrinsic properties of the object presented. Expand
