Decreased activity in inferotemporal cortex during explicit memory: dissociating priming, novelty detection, and recognition.

Studies of non-human primates have shown that activity in inferotemporal (IT) brain regions decrease over repeated stimulus exposure, a phenomenon known as repetition suppression. In the present study, repetition suppression was examined during ...

Superior digit memory of abacus experts: an event-related functional MRI study.

Abacus experts exhibit superior short-term memory for digits, but the underlying neurophysiological mechanism remains unknown. Using event-related fMRI, we examined the brain activity of abacus experts and non-experts during the memory retention period ...

Driving safety in Parkinsons disease.

In this study, 39 patients with PD and 25 control subjects without neurologic disease completed testing in a driving simulator. PD patients had more total collisions on the driving simulator than control subjects (t = -3.7, p < 0.01). In PD patients, ...

My eyes want to look where your eyes are looking: exploring the tendency to imitate another individuals gaze.

In this study we investigated the tendency of humans to imitate the gaze direction of other individuals. Distracting gaze stimuli or non biological directional cues (arrows) were presented to observers performing an instructed saccadic eye movement task. ...

A neural network elicited by parametric manipulation of the attention load.

We used a parametric experimental design to identify the rCBF variations related to a continuous variation of the attention load. The experiment involved goal-directed visual tasks. The length of time during which the subjects attention was engaged ...

Schizophrenia in males of cognitive performance: discriminative and diagnostic values.

OBJECTIVE: To evaluate the discriminative and diagnostic values of neuropsychological tests for identifying schizophrenia patients. METHODS: A cross-sectional study with 36 male schizophrenia outpatients and 72 healthy matched volunteers was carried out. ...

The incremental direct costs associated with behavioral symptoms in AD.

OBJECTIVE: To determine the incremental costs associated with behavioral symptoms in patients with AD. METHODS: A total of 128 patients with probable AD were enrolled into this study. Cognitive function and extrapyramidal features were assessed in ...

Neuropsychological performance in schizotypal personality disorder: evidence regarding diagnostic specificity.

BACKGROUND: Individuals with schizotypal personality disorder (SPD) share cognitive deficits with schizophrenic patients, suggesting that these deficits represent a core feature of the schizophrenia spectrum. We investigated the neuropsychological ...

Developmental event-related gamma oscillations: effects of auditory attention.

This study describes maturational changes in topographical patterns, stability, and functional reactivity of auditory gamma band (31-63 Hz) responses (GBRs) as brain electrical correlates relevant for cognitive development during childhood. GBRs of 114 ...

The association of incident dementia with mortality in PD.

OBJECTIVE: To evaluate the association of incident dementia with mortality in a cohort of patients with idiopathic PD who were nondemented at baseline evaluation, controlling for extrapyramidal sign (EPS) severity at each study visit. BACKGROUND: The ...
