A SEEG study of ERP in motor and premotor cortices and in the basal ganglia.

OBJECTIVE: Our intention was to study the electrical activity related to the cognitive processing of simple sensory stimuli in the brain structures that participate in motor control. We focused our interest on the 250-600 ms time window, in which ...

Stimulus characteristics and task category dissociate the anterior and posterior aspects of the novelty P3.

The novelty P3 is an event-related potential component that is most often elicited by environmental sounds within the "novelty oddball" paradigm. Within the context of this paradigm, it is not clear if the novelty P3 can be elicited by deviant stimuli ...

Concurrent task effects on memory retrieval.

Previous studies combining continuous free recall with a concurrent task have generally shown that concurrent tasks impose fairly negligible effects on memory retrieval. By contrast, dual-task studies employing either cued recall or semantic retrieval ...

Visual awareness of low-contrast stimuli is reflected in event-related brain potentials.

Visual awareness was studied in 11 subjects by using coherent and scrambled objects as stimuli. The stimuli were presented near the subjective perceptual threshold. Explicitly recognized stimuli elicited a specific negative ERP deflection peaking at 460 ...

Locus of semantic interference in picture-word interference tasks.

Picture-word interference studies typically show that semantically related distractor words embedded within a picture slow picture-naming responses, relative to unrelated ones. This semantic interference effect is commonly interpreted as arising from the ...

Effects of exercise on somatosensory-evoked potentials.

The aim of this study was to investigate the effect of acute and regular exercise on somatosensory-evoked potentials (SEP). The study group was designed as 9 female and 7 male volleyball players, and the control group as 9 female and 7 male sedentary ...

The effect of dehydroepiandrosterone (DHEA) on recognition memory decision processes and discrimination in postmenopausal women.

In this article, the theoretical distinction between recognition memory decision and discrimination processes is used to explore the effect of dehydroepiandrosterone (DHEA) in postmenopausal women. DHEA is an adrenal steroid that diminishes with aging. ...

Recognizing rotated views of objects: interpolation versus generalization by humans and pigeons.

Pigeons and humans were trained to discriminate between pictures of three-dimensional objects that differed in global shape. Each pair of objects was shown at two orientations that differed by a depth rotation of 90 degrees during training. Pictures of ...

Effects of serial visuomotor tasks on contingent negative variation.

We evaluated contingent negative variation (CNV) in 15 right-handed normal subjects who performed simple finger extension(NB) or skilled finger movement task with visual guidance (B). When subjects performed serial tasks of NB-B1 (first block of B)-B2 ...

Decision-bound theory and the influence of familiarity.

In this article, we derive a nonparametric prediction from decision-bound theory (DBT). The crucial aspect that is tested is whether or not familiarity of a stimulus affects response time in categorization. We show that, for our design, DBT, extended ...
