Medial temporal lobe activity can distinguish between old and new stimuli independently of overt behavioral choice.

15 Aug 2009 We collected fMRI data and confidence ratings as participants performed a recognition memory task that intermixed recently studied words and new (non-studied) words. We first replicated a typical finding from such studies; namely, increasing ...

Suppression of human cortico-motoneuronal excitability during the Stop-signal task.

13 Aug 2009 OBJECTIVE: To investigate whether motor suppression is an active process, and to clarify its somatotopic organization, we investigated cortico-motoneuronal excitability using transcranial magnetic stimulation (TMS) during the Stop-signal task. ...

Long-term maintenance of retest learning in young old and oldest old adults.

11 Aug 2009 This study examined the maintenance of retest learning benefits in young old and oldest old adults over an 8-month period in 3 cognitive abilities: reasoning, perceptual-motor speed, and visual attention. Twenty-four young old (aged 70-79 years, M = ...

Motor learning is optimally tuned to the properties of motor noise.

11 Aug 2009 In motor learning, our brain uses movement errors to adjust planning of future movements. This process has traditionally been studied by examining how motor planning is adjusted in response to visuomotor or dynamic perturbations. Here, I show that ...

Category-specific organization in the human brain does not require visual experience.

11 Aug 2009 Distinct regions within the ventral visual pathway show neural specialization for nonliving and living stimuli (e.g., tools, houses versus animals, faces). The causes of these category preferences are widely debated. Using functional magnetic ...

Serial, covert shifts of attention during visual search are reflected by the frontal eye fields and correlated with population oscillations.

11 Aug 2009 Attention regulates the flood of sensory information into a manageable stream, and so understanding how attention is controlled is central to understanding cognition. Competing theories suggest visual search involves serial and/or parallel ...

Effects of task complexity and sensory conflict on goal-directed movement.

10 Aug 2009 Interactions between brain regions are necessary for compound activities to take place. Accordingly, evaluating hemispheric information processing during skilled behaviour provides valuable knowledge about brain regulation. To this end, the present ...

Functional connectivity delineates distinct roles of the inferior frontal cortex and presupplementary motor area in stop signal inhibition.

10 Aug 2009 The neural basis of motor response inhibition has drawn considerable attention in recent imaging literature. Many studies have used the go/no-go or stop signal task to examine the neural processes underlying motor response inhibition. In particular, ...

Shift from hippocampal to neocortical centered retrieval network with consolidation.

10 Aug 2009 The standard model of system-level consolidation posits that the hippocampus is part of a retrieval network for recent memories. According to this theory, the memories are gradually transferred to neocortical circuits with consolidation, where the ...

Implicit association between basic tastes and pitch.

9 Aug 2009 Our evaluation of food is influenced by a variety of contextual information perceived via the senses. Here we investigated whether there are interactions between auditory stimuli and basic tastes (indicated by the names of typically sour and bitter ...
