An fMRI study investigating cognitive modulation of brain regions associated with emotional processing of visual stimuli.

Brain regions modulated by cognitive tasks during emotional processing were investigated using fMRI. Participants performed indirect and direct emotional processing tasks on positive and negative faces and pictures. We used a multivariate technique, ...

Dopaminergic modulation of visual-spatial working memory in Parkinsons disease.

Visual-spatial working memory (WM) impairment is frequently associated with the early stage of Parkinsons disease (PD). The aim of this study was to evaluate the performance of a group of PD patients in visual-spatial and visual-object WM tasks and to ...

A procedure for identifying regions preferentially activated by attention to semantic and phonological relations using functional magnetic resonance imaging.

A procedure is introduced for using functional magnetic resonance imaging (fMRI) techniques to identify neural regions associated with attention to semantic and phonological aspects of written words within a single group of subjects. Short lists (16 ...

Investigating the cognitive neuroscience of social behavior.

Social cognitive neuroscience is a fledgling discipline that has already accrued an impressive body of data, but important questions remain regarding the theoretical constructs and methodological approaches that it utilizes. An overview of the papers in ...

Switching attention and resolving interference: fMRI measures of executive functions.

Is there a single executive process or are there multiple executive processes that work together towards the same goal in some task? In these experiments, we use counter switching and response inhibition tasks to examine the neural underpinnings of two ...

Memory orientation and success: separable neurocognitive components underlying episodic recognition.

Episodic recognition can be based on recollection of contextual details, on a sense of recent encounter, or some combination of the two. According to several cognitive models, selectively attending to these distinct aspects of memory may require ...

A model of risk for major depression: effects of life stress and cognitive style vary by age.

Empirical studies increasingly attribute risk for depression to adverse life events, cognitive style, and possibly to the interaction between cognitive style and event type. We present an evidence-based model, developed with independent samples of adults ...

Disambiguating conscious and unconscious influences: do exclusion paradigms demonstrate unconscious perception?

Does exclusion failure--responding with previously presented words despite instructions to avoid doing so--demonstrate unconscious influences? This article examines exclusion-based evidence for unconscious perception. I propose an alternative signal ...

Single-trial classification of elementary comparison processes on the basis of instantaneous EEG and MEG coherences.

The present study is focused on the evidence of possible single-trial EEG/MEG analysis of information processing. The discrimination between thinking modalities of concept activation and pattern comparison for single tasks of elementary comparison ...

Déjà vu: possible parahippocampal mechanisms.

Déjà vu experiences are common in normal subjects. In addition, they are established symptoms of temporal lobe seizures. The author argues that the phenomenon is the result of faulty and isolated activity of a recognition memory system that consists of ...
