Involvement of striate and extrastriate visual cortical areas in spatial attention
TLDR
Event-related potentials (ERPs) and modeling of their neural sources indicated that the initial sensory input to striate cortex at 50–55 milliseconds after the stimulus was not modulated by attention, whereas the earliest facilitation of attended signals was observed in extrastriate visual areas. Expand
Unconscious determinants of free decisions in the human brain
TLDR
It is found that the outcome of a decision can be encoded in brain activity of prefrontal and parietal cortex up to 10 s before it enters awareness. Expand
Combined spatial and temporal imaging of brain activity during visual selective attention in humans
TLDR
Together neuroimaging and e.r.p. recording showed that visual inputs from attended locations receive enhanced processing in the extrastriate cortex (fusiform gyrus) at 80–130 ms after stimulus onset, which reinforces early selection models of attention. Expand
Mesolimbic Functional Magnetic Resonance Imaging Activations during Reward Anticipation Correlate with Reward-Related Ventral Striatal Dopamine Release
TLDR
Evidence is provided that dopaminergic neurotransmission plays a quantitative role in human mesolimbic reward processing and the combined neurochemical and hemodynamic imaging approach used here opens up new perspectives for the investigation of molecular mechanisms underlying human cognition. Expand
Shared networks for auditory and motor processing in professional pianists: Evidence from fMRI conjunction
TLDR
A conjunction analysis revealed a distinct musicianship-specific network being co-activated during either task type, indicating areas involved in auditory-sensorimotor integration in professional musicians. Expand
Focal thinning of the cerebral cortex in multiple sclerosis.
TLDR
In vivo measurement of cortical thickness is concluded to be feasible in patients suffering from multiple sclerosis, revealing focal cortical thinning beside an overall reduction of the cortical thickness with disease progression. Expand
Reward-Related fMRI Activation of Dopaminergic Midbrain Is Associated with Enhanced Hippocampus- Dependent Long-Term Memory Formation
TLDR
FMRI activity in the hippocampus and the midbrain was higher for reward-predicting pictures that were later recognized compared with later forgotten pictures, consistent with the hypothesis that activation of dopaminergic midbrain regions enhances hippocampus-dependent memory formation, possibly by enhancing consolidation. Expand
Visual event-related potentials index focused attention within bilateral stimulus arrays. II. Functional dissociation of P1 and N1 components.
TLDR
It was concluded that modulations of the N1 and P1 components in these experiments represent different aspects of visual spatial attention: N1 may represent the orienting of attention to a task-relevant stimulus, whereas P1 may represents a facilitation of early sensory processing for items presented to a location where attention is already focused. Expand
Neural sources of focused attention in visual search.
TLDR
Findings are consistent with the proposal that parietal areas are used to initiate a shift of attention within a visual search array and that the focusing of attention is implemented by extrastriate areas of the occipital and inferior temporal cortex. Expand
Delayed Striate Cortical Activation during Spatial Attention
TLDR
Findings provide evidence that the primary visual cortex participates in the selective processing of attended stimuli by means of delayed feedback from higher visual-cortical areas. Expand
