Changes in linear and nonlinear EEG measures as a function of task complexity: evidence for local and distant signal synchronization.

The purpose of the present study was threefold: First, to replicate previous findings of changes in local gamma band power as a function of the complexity of a visuo-semantic processing task, second, to extend these findings in tasks delivered in the ...

P3a from visual stimuli: typicality, task, and topography.

A visual three-stimulus (target, nontarget, standard) paradigm was employed in which subjects responded only to the target. Nontarget stimulus properties were varied systematically to evaluate how stimulus typicality (non-novel vs. novel) across task ...

Inhibition and attention deficit hyperactivity disorder in adults.

The inhibitory account of attention deficit hyperactivity disorder (ADHD) was tested by examining the performance of college-aged adults on a variety of inhibitory tasks. The poorer performance of adults with ADHD compared with controls on negative ...

Magical ideation modulates spatial behavior.

Previous research has found that animals as well as persons with psychotic disorders preferentially orient away from the cerebral hemisphere with the more active dopamine system. This study investigated the modulation of spatial behavior by a mode of ...

The effects of enhanced visual feedback on human synchronization.

The execution of actions not only reposes on the spatial and temporal organization of the movements as such but also on their appropriate imbedding into the environmental spatio-temporal constraints. Actually, performance outcome appears to be strongly ...

Normal pressure hydrocephalus triggers intrathecal production of TNF-alpha.

Normal pressure hydrocephalus (NPH) is associated with periventricular white matter lesions and demyelination. The aim of the present study was to examine the cerebrospinal fluid (CSF) levels of tumor necrosis factor-alpha (TNF-alpha), a proinflammatory ...

Catching oriented objects.

We have investigated how participants match the orientation of a line, which moves on a vertical screen towards the subject. On its path to the participant, the line could disappear at several positions. Participants were instructed to put a bar on a ...

Psychomotor skills assessment in practicing surgeons experienced in performing advanced laparoscopic procedures.

BACKGROUND: Minimally invasive surgery (MIS) has introduced a new and unique set of psychomotor skills for a surgeon to acquire and master. Although assessment technologies have been proposed, precise and objective psychomotor skills assessment of ...

The effect of a micronutrient-fortified complementary food on micronutrient status, growth and development of 6- to 12-month-old disadvantaged urban South African infants.

The study was conducted to look at the effectiveness of a multimicronutrient-fortified complementary food on the micronutrient status, linear growth and psychomotor development of 6- to 12-month-old infants from a black urban disadvantaged community in ...

Motor control and children with autism: deficit of anticipatory function?

This study aims at investigating how do anticipatory postural adjustments develop in children with autism, during a bimanual load-lifting task that required maintaining the stabilisation of the forearm despite imposed or voluntary unloading. Elbow angle ...
