Cant shake that feeling: event-related fMRI assessment of sustained amygdala activity in response to emotional information in depressed individuals.

BACKGROUND: Previous research suggests that depressed individuals engage in prolonged elaborative processing of emotional information. A computational neural network model of emotional information processing suggests this process involves sustained ...

The relationship between rhythmic activities during a mental task and sleep spindles: a correlative analysis.

In a previous study, we suggested that the characteristics of theta, alpha, and beta rhythms during a mental task were similar to those during sleep. Building upon the previous data, correlations between rhythmic activities during a mental task and ...

Effects of picture repetition on induced gamma band responses, evoked potentials, and phase synchrony in the human EEG.

Repeated experience with an object due to prior exposure to that object is commonly referred to as perceptual or repetition priming. One possible neuronal mechanism for repetition priming is repetition suppression within a cell assembly coding the ...

Naive causal understanding of valenced behaviors and its implications for social information processing.

People bring to bear on their understanding of others behaviors naive theories of the causes of valenced behaviors. Generally, positive behaviors are understood to be caused by social demands, whereas negative behaviors are understood to be caused by ...

The interplay of meaning, sound, and syntax in sentence production.

A discussion of modularity in language production processes, with special emphasis on processes for retrieving words and building syntactic structures for a to-be-uttered sentence, is presented. The authors 1st goal was to assess the extent to which ...

Event-related potentials during discourse-level semantic integration of complex pictures.

This study examined event-related potentials (ERPs) elicited in response to semantic processing of non-verbal stories. ERPs were recorded from 29 scalp electrodes on 16 participants while they viewed series of complex gray-scale pictures, each of which ...

The integration of neurology, psychiatry, and neuroscience in the 21st century.

OBJECTIVE: This article examines the historical basis for the divergence of neurology and psychiatry over the past century and discusses prospects for a rapprochement and potential convergence of the two specialties in the next century. METHOD: The ...

Task switching: a PDP model.

When subjects switch between a pair of stimulus-response tasks, reaction time is slower on trial N if a different task was performed on trial N - 1. We present a parallel distributed processing (PDP) model that simulates this effect when subjects switch ...

A qualitative and quantitative analysis of rhythmic activities during a mental task and sleep spindles.

The frequency, configuration, and distribution of sleep spindles are similar to some of the rhythmic activities seen during task performance. In the present study, the relationship between rhythmic activities during sleep and arithmetic addition was ...

Sustained mnemonic response in the human middle frontal gyrus during on-line storage of spatial memoranda.

The mapping of cognitive functions to neural systems is a central goal of cognitive neuroscience. On the basis of homology with lesion and physiological studies in nonhuman primates, Brodmanns area (BA) 46/9 in the middle frontal gyrus (MFG) has been ...
