Cognitive processing of anorexic patients in recognition tasks: an event-related potentials study.

OBJECTIVE: We used event-related potentials (ERPs) to test whether anorexic subjects have difficulties in filtering out irrelevant stimuli in controlled information processing tasks. METHODS: ERPs from 12 anorexic patients were recorded during ...

An attention modulated response to disgust in human ventral anterior insula.

The human brain is expert in analyzing rapidly and precisely facial features, especially emotional expressions representing a powerful communication vector. The involvement of insula in disgust recognition has been reported in behavioral and functional ...

A direct prefrontotectal tract against distractibility in the human brain.

Distractibility, which can be defined as an attention deficit in which orientation toward irrelevant targets can be hardly inhibited, is commonly related to a dysfunction of the dorsolateral prefrontal cortex. Here, we show that increased ...

Hemispheric balance in processing attended and non-attended vowels and complex tones.

We compared cortical processing of attended and non-attended vowels and complex tones, using a whole-head neuromagnetometer, to test for possible hemispheric differences. Stimuli included vowels [a] and [i], spoken by two female Finnish speakers, and two ...

The processing of emotional facial expression is gated by spatial attention: evidence from event-related brain potentials.

To investigate whether the processing of faces and emotional facial expression can be modulated by spatial attention, ERPs were recorded in response to stimulus arrays containing two faces and two non-face stimuli (houses). In separate trials, attention ...

Attentional set for external information activates the right intraparietal area.

Visual attention can be allocated to a location or an object by using two different types of information: internal information and external information. The results of recent psychological studies [Bagon and Egeth, Percept. Psychophys. 55 (1994) 485] ...

The mismatch negativity and reaction time as indices of the perceptual distance between the corresponding vowels of two related languages.

Two experiments were conducted to determine whether vowel familiarity affects automatic and conscious vowel discrimination. Familiar (Finnish) and unfamiliar (Komi) vowels were presented to Finnish subjects. The good representatives of Finnish and Komi ...

Focused attention in a simple dichotic listening task: an fMRI experiment.

Whole-head functional magnetic resonance imaging (fMRI) was used in nine neurologically intact subjects to measure the hemodynamic responses in the context of dichotic listening (DL). In order to eliminate the influence of verbal information processing, ...

Auditory selective attention modulated by tryptophan depletion in humans.

To elucidate serotonin modulation of selective attention, 13 volunteers (21-30 years) were studied in two sessions, 5 h after either acute tryptophan depletion (ATD) that decreases brain serotonin synthesis, or control-mixture ingestion (randomized, ...

The effects of attention on speech perception: an fMRI study.

Focusing of attention to a specific speech source plays an important role in everyday speech perception. However, little is known of the neuronal substrates of focused attention in speech perception. Thus, the present study investigated the effects on ...
