Multisensory congruency as a mechanism for attentional control over perceptual selection.
14 Sep 2009 
The neural mechanisms underlying attentional selection of competing neural signals for awareness remains an unresolved issue. We studied attentional selection, using perceptually ambiguous stimuli in a novel multisensory paradigm that combined ...

Decisions in changing conditions: the urgency-gating model.
14 Sep 2009 Several widely accepted models of decision making suggest that, during simple decision tasks, neural activity builds up until a threshold is reached and a decision is made. These models explain error rates and reaction time distributions in a ...

The representation of tool use in humans and monkeys: common and uniquely human features.
14 Sep 2009 Though other species of primates also use tools, humans appear unique in their capacity to understand the causal relationship between tools and the result of their use. In a comparative fMRI study, we scanned a large cohort of human volunteers and ...

The convergence of information about rewarding and aversive stimuli in single neurons.
14 Sep 2009 Neuroscientists, psychologists, clinicians, and economists have long been interested in how individuals weigh information about potential rewarding and aversive stimuli to make decisions and to regulate their emotions. However, we know relatively ...

14 Sep 2009 Neural activity was recorded in area PE (dorsorostral part of Brodmann's area 5) of the posterior parietal cortex while monkeys performed arm reaching toward memorized targets located at different distances from the body. For any given distance, arm ...

Coding of stimulus sequences by population responses in visual cortex.
11 Sep 2009 Neuronal populations in sensory cortex represent time-changing sensory input through a spatiotemporal code. What are the rules that govern this code? We measured membrane potentials and spikes from neuronal populations in cat visual cortex (V1) ...

9 Sep 2009 It has been proposed that psychophysiological abnormalities in schizophrenia, such as decreased amplitude of the evoked potential component P300, may be genetically influenced. Studies of heritability of the P300 have used different and typically ...

Recollection, familiarity, and cortical reinstatement: a multivoxel pattern analysis.
8 Sep 2009 Episodic memory retrieval is thought to involve reinstatement of the neurocognitive processes engaged when an episode was encoded. Prior fMRI studies and computational models have suggested that reinstatement is limited to instances in which ...

The eyes have it: hippocampal activity predicts expression of memory in eye movements.
8 Sep 2009 Although there is widespread agreement that the hippocampus is critical for explicit episodic memory retrieval, it is controversial whether this region can also support indirect expressions of relational memory when explicit retrieval fails. Here, ...

7 Sep 2009 Fourteen men scoring high and 14 men scoring low on a positive schizotypy scale participated in a lateralized emotional Stroop task. Vocal reaction times for color naming of neutral, positive and negative emotional words were recorded. Across ...
