A-waves and electrophysiologically established diagnoses.

The aim of this study was to investigate the presence of A-waves in cases referred to our electromyography laboratory with various diagnoses and documentation of electrophysiologic diagnoses with A-waves. In cases where at least 3 motor nerves were ...

Enhanced intensity dependence as a marker of low serotonergic neurotransmission in borderline personality disorder.

Dysfunction of central serotonergic activity has been assumed in patients with borderline personality disorder (BPD) characterized by a prominent impulsive behavioral style. Following the high serotonergic innervation of the primary auditory cortex, ...

Cognitive inhibition and thought disorder in schizophrenia.

In schizophrenia, inhibitory control is reported to be disturbed and has been associated with formal thought disorder (TD). The negative priming task (NP) is used as a measure for inhibition; however, controversial results are found in the literature. ...

Serum cholesterol, precursors and metabolites and cognitive performance in an aging population.

The present study investigated if a causal relation exists between serum concentrations of precursors and metabolites of cholesterol and cognitive performance in a healthy aging population.Cognitive function addressing four domains of 144 individuals ...

Are fingers special? Evidence about movement preparation from event-related brain potentials.

Ulrich, Leuthold, and Sommer (1998) suggested that movement preparation at the level of the motor cortex, as indexed by the lateralized readiness potential (LRP), proceeds in a strongly hierarchical fashion, where parameters other than response hand are ...

ERP correlates of true and false recognition after different retention delays: stimulus- and response-related processes.

Performance and electrophysiological correlates of true and false recognition were examined after short (40 s) and long (80 s) delays. True recognition showed no significant decrease after a long delay, whereas false recognition increased. Early frontal ...

Development of pro- and antisaccades in children with attention-deficit hyperactivity disorder (ADHD) and healthy controls.

To date, the investigation of the antisaccade task, a simple test of "executive functions," in children with ADHD has yielded inconsistent results. The present study aimed at contributing to this issue by (a) the investigation of a large sample of ...

Effect of high altitude (HA) on event related brain potentials.

Event Related brain potentials (ERPs) were recorded in 15 subjects using standard auditory odd ball paradigm, in which subjects were presented a sequence of two distinguishable sound stimuli of that occurred frequently (frequently (frequent stimulus-non ...

A proper metaphysics for cognitive performance.

The general failure to individuate component causes in cognitive performance suggests the need for an alternative metaphysics. The metaphysics of control hierarchy theory accommodates the fact of self-organization in nature and the possibility that ...

Feature-specific electrophysiological correlates of texture segregation.

Discrimination between a figure and its surround is an important first step of pattern recognition. This discrimination usually relies, as a first step, on the detection of borders between a figure and its surround, for example based on spatial gradients ...
