Electroencephalographic signatures of attentional and cognitive default modes in spontaneous brain activity fluctuations at rest.

We assessed the relation between hemodynamic and electrical indices of brain function by performing simultaneous functional MRI (fMRI) and electroencephalography (EEG) in awake subjects at rest with eyes closed. Spontaneous power fluctuations of ...

Cognitive reserve and lifestyle.

The concept of cognitive reserve (CR) suggests that innate intelligence or aspects of life experience like educational or occupational attainments may supply reserve, in the form of a set of skills or repertoires that allows some people to cope with ...

Differential activity in the premotor cortex subdivisions in humans during mental calculation and verbal rehearsal tasks: a functional magnetic resonance imaging study.

To investigate a possible role of the lateral premotor cortex in human cognitive processes, we compared brain activity during mental-operation numeral (MO-numeral) and verbal rehearsal (VR) tasks, using block-design functional MRI. Sixteen healthy ...

Aperiodic phase re-setting in scalp EEG of beta-gamma oscillations by state transitions at alpha-theta rates.

We evaluated the rapid changes in regional scalp EEG synchronization in normal subjects with spatial and temporal resolution exceeding prior art 10-fold with a high spatial density array and the Hilbert transform. A curvilinear array of 64 electrodes 3 ...

Is patient-reported function reliable for monitoring postacute outcomes?

OBJECTIVE: A major challenge in the development of a comprehensive measurement system to evaluate effectiveness across a broad range of postacute care settings is the stability and consistency of outcomes measures across respondents and settings. The ...

Alterations in theory of mind in patients with schizophrenia and non-psychotic relatives.

OBJECTIVE: It has been proposed that alterations in theory of mind underlie specific symptoms of psychosis. The present study examined whether alterations in theory of mind reflect a trait that can be detected in non-psychotic relatives of patients with ...

Cognition and aging: a highly selective overview of event-related potential (ERP) data.

An overview of highly selected cognitive aging investigations of deviance detection, episodic memory and working memory reveals two primary themes: (1) when variability in elderly samples has been assessed, it has proven useful in understanding ...

Assessment of lifetime participation in cognitively stimulating activities.

Cognitively stimulating experience is thought to contribute to cognitive reserve. We constructed a questionnaire consisting of 25 items about frequency of participation in cognitive activities across the life span and administered it to two groups of ...

Comparison of cognitive performances during a placebo period and an atypical antipsychotic treatment period in schizophrenia: critical examination of confounds.

Although previous studies report cognitive improvement following atypical antipsychotic administration in schizophrenia (SC), few placebo-controlled within-subject studies with examination of confounds (symptom reduction, cooperation, learning, and ...

Lifetime antecedents of cognitive reserve.

We used path analysis on data from the British 1946 birth cohort to model lifetime antecedents of cognitive reserve, represented by the NART at 53 years, and compared this model for verbal memory and psychomotor function at this age, cognitive outcomes ...
