Modulation of aesthetic value by semantic context: An fMRI study
Aesthetic judgments, like most judgments, depend on context. Whether an object or image is seen in daily life or in an art gallery can significantly modulate the aesthetic value humans attach to it.Expand

Bayesian decoding of brain images
TLDR
This paper introduces a multivariate Bayesian (MVB) scheme to decode or recognise brain states from neuroimages. Expand

The Known Unknowns: Neural Representation of Second-Order Uncertainty, and Ambiguity
Predictions provided by action-outcome probabilities entail a degree of (first-order) uncertainty. However, these probabilities themselves can be imprecise and embody second-order uncertainty.Expand

Motivational Tuning of Fronto-Subthalamic Connectivity Facilitates Control of Action Impulses
It is critical for survival to quickly respond to environmental stimuli with the most appropriate action. This task becomes most challenging when response tendencies induced by relevant andExpand

The sightless view: neural correlates of occluded objects.
The relationship between neural activity and object perception has received considerable attention using stimulus manipulations such as masking or dichoptic presentation. Here we investigate the sameExpand

Effects of Category-Specific Costs on Neural Systems for Perceptual Decision-Making
Perceptual judgments are often biased by prospective losses, leading to changes in decision criteria. Little is known about how and where sensory evidence and cost information interact in the brainExpand

Attenuated neural response to gamble outcomes in drug-naive patients with Parkinson's disease.
Parkinson's disease results from the degeneration of dopaminergic neurons in the substantia nigra, manifesting as a spectrum of motor, cognitive and affective deficits. Parkinson's disease alsoExpand

Spatially Distributed Encoding of Covert Attentional Shifts in Human Thalamus
Spatial attention modulates signal processing within visual nuclei of the thalamus—but do other nuclei govern the locus of attention in top-down mode? We examined functional MRI (fMRI) data fromExpand

Simultaneous representation of a spectrum of dynamically changing value estimates during decision making
TLDR
We show that dorsal anterior cingulate cortex and three other brain regions hold multiple representations of choice value based on different timescales of experience organized in terms of systematic gradients across the cortex. Expand

Neural Correlates of Stimulus Reportability
TLDR
We investigate the neural correlates of stimulus reportability using a partial report object detection paradigm. Expand
