Electrophysiology of the frontal lobe.

The electrophysiology of the frontal lobe appears to be unimpressive when the view is limited to the routine EEG recording of a healthy waking adult. There is usually low voltage fast activity, which becomes more pronounced when recorded with depth ...

Head position modulates activity in the human parietal eye fields.

For us to interact with our environment we need to know where objects are around us, relative to our body. In monkeys, a body-centered map of visual space is known to exist within the parietal eye fields. This map is formed by the modulation of retinal ...

The Multi-Source Interference Task: validation study with fMRI in individual subjects.

Dorsal anterior cingulate cortex (dACC) plays critical roles in cognitive processing, but group-averaging techniques have generally been required to obtain significant dACC activation in functional neuroimaging studies. Development of a task that ...

When visuo-motor incongruence aids motor performance: the effect of perceiving motion structures during transformed visual feedback on bimanual coordination.

Two experiments are reported in which bimanual coordination tasks were performed under correct and transformed visual feedback conditions. Participants were to generate cyclical line-drawing patterns, with varying degrees of coordinative stability, while ...

Mutational analysis of the nicotinic acetylcholine receptor alpha 4 subunit gene in attention deficit/hyperactivity disorder: evidence for association of an intronic polymorphism with attention problems.

Recent studies suggest the presence of genetically distinct subtypes of attention deficit/hyperactivity disorder (ADHD) and that attention problems can be treated with receptor subtype selective nicotine agonists. In this study, individuals with two ...

Goal-referenced selection of verbal action: modeling attentional control in the Stroop task.

This article presents a new account of the color-word Stroop phenomenon (J. R. Stroop, 1935) based on an implemented model of word production, WEAVER++ (W. J. M. Levelt, A. Roelofs, & A. S. Meyer, 1999b; A. Roelofs, 1992, 1997c). Stroop effects are ...

Functional specialization within the anterior medial prefrontal cortex: a functional magnetic resonance imaging study with human subjects.

This study investigated the functional neuroanatomy of the anterior medial prefrontal cortex (aMPFC). Previous studies have shown that the aMPFC is involved in evaluative judgment and self-referential processes. Specifically, different sections of the ...

Qualitative analysis of verbal fluency in depression.

The aim of this study was to analyze qualitative aspects of verbal fluency in depression. Phonemic and semantic output was scored for word clustering and switching between clusters in depressed patients and normal control subjects. Depressed patients ...

The selective tuning model of attention: psychophysical evidence for a suppressive annulus around an attended item.

The selective tuning model [Artif. Intell. 78 (1995) 507] is a neurobiologically plausible neural network model of visual attention. One of its key predictions is that to simultaneously solve the problems of convergence of neural input and selection of ...

Olfaction and depth of word processing: a magnetoencephalographic study.

Using a whole-cortex magnetoencephalograph, magnetic field changes were recorded to describe brain activities related to simultaneous visual and olfactory processing and to detect odor-related influences on verbal information processing. Words had to be ...
