Enhanced extrastriate activation during observation of distorted finger postures.

Hand and finger postures of other people are important body language cues that strongly contribute to the observers decision about the persons intentions, thoughts, and attentional state. We compared neuromagnetic cortical activation elicited by color ...

Children processing music: electric brain responses reveal musical competence and gender differences.

Numerous studies investigated physiological correlates of the processing of musical information in adults. How these correlates develop during childhood is poorly understood. In the present study, we measured event-related electric brain potentials ...

Identical event-related potentials to target and frequent stimuli of visual oddball task recorded by intracerebral electrodes.

OBJECTIVE: The shape of visually elicited event-related potentials (ERP) of epileptic patients during their presurgical evaluation with intracerebral electrodes was investigated in the study. METHODS: Twenty intractable epileptic patients with depth ...

The spatial distribution of attentional selectivity in touch: evidence from somatosensory ERP components.

OBJECTIVE: Somatosensory event-related brain potentials (ERPs) were measured to investigate the spatial distribution of selective attention in touch, and whether the focus of tactile attention can be split between non-contiguous areas of the body ...

The neuropsychological profiles of mild Alzheimers disease and questionable dementia as compared to age-related cognitive decline.

Test scores from a comprehensive neuropsychological battery administered to 1602 subjects consisting of 1347 subjects with probable Alzheimers disease (AD), 100 subjects with questionable dementia (QD) and 155 non-demented elderly control subjects were ...

Apathy and cognitive performance in older adults with depression.

OBJECTIVES: Recent studies have linked apathy to frontal lobe dysfunction in persons with dementia, but few studies have explored this relationship in older, depressed persons without dementia. We examined the association between apathy and cognitive ...

Effect of cognitive and motor tasks on postural stability in Parkinsons disease: a posturographic study.

To analyse the effect of concomitant cognitive or motor task performance on balance control in Parkinsons disease (PD), we performed a posturographic study in 24 PD patients and in 20 sex- and age-matched control subjects. Postural sway was measured with ...

Neuropsychological performance and regional cerebral blood flow in obsessive-compulsive disorder.

Convergent findings from neuropsychological and neuroimaging studies have suggested that neural dysfunction in frontal-subcortical circuits may play a central role in the pathophysiology of obsessive-compulsive disorder (OCD). To further examine the ...

Is synchronized neuronal gamma activity relevant for selective attention?

Today, much evidence exists that sensory feature binding is accomplished by phase synchronization of induced neuronal gamma activity (30-80 Hz). Recent studies furthermore suggest that phase synchronization of induced gamma activity may represent a ...

On the interaction between perceptual and response selection: neuropsychological evidence.

We examined the relations between selection for perception and selection for action in a patient FK, with bilateral damage to his temporal and medial frontal cortices. The task required a simple grasp response to a common object (a cup) in the presence ...
