Background EEG studies of working memory (WM) have demonstrated load dependent
frequency band modulations. FMRI studies have localized load modulated activity to the …

OBJECTIVE: Theta and alpha range EEG oscillations are commonly induced in cognitive
tasks, but their possible relationship to the BOLD signal of fMRI is not well understood, and …

PET and fMRI experiments have previously shown that several brain regions in the frontal
and parietal lobe are involved in working memory maintenance. MEG and EEG experiments …

We show that during visual working memory, the electroencephalographic (EEG) process
producing 5–7 Hz frontal midline theta (fmθ) activity exhibits multiple spectral modes …

Similar to the occipital alpha rhythm, electroencephalographic (EEG) signals in the alpha-
and beta-frequency bands can be suppressed by movement or motor imagery and have …

Previous studies in electrophysiology have provided consistent evidence for a relationship
between neural oscillations in different frequency bands and the maintenance of information …

Multi‐item working memory (WM) is a complex cognitive function thought to arise from
specific frequency band oscillations and their interactions. While some theories and …

Although resting‐state brain activity has been demonstrated to correspond with task‐evoked
brain activation, the relationship between intrinsic and evoked brain activity has not been …

Electrocorticography (ECoG) and functional MRI (BOLD–fMRI) have been used previously to
measure brain activity during working memory delay periods. These studies have separately …

Although recent neuroimaging studies suggest that prefrontal cortex (PFC) is involved in
working memory (WM), the relationship between PFC activity and memory load has not yet …
