Journal ArticleDOI

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

Helmut Laufs, +6 more
- 16 Sep 2003 - 
TL;DR: It is suggested that alpha oscillations signal a neural baseline with “inattention” whereas beta rhythms index spontaneous cognitive operations during conscious rest, and that activity in these networks is associated with distinct EEG signatures.
Journal ArticleDOI

EEG-correlated fMRI of human alpha activity.

Helmut Laufs, +6 more
- 01 Aug 2003 - 
TL;DR: Continuous and simultaneous EEG/fMRI is implemented to identify BOLD signal changes related to spontaneous power fluctuations in the alpha rhythm, the dominant EEG pattern during relaxed wakefulness, and a strong negative correlation of parietal and frontal cortical activity with alpha power was found.
Journal ArticleDOI

Blockade of "NMDA" receptors disrupts experience-dependent plasticity of kitten striate cortex

Andreas Kleinschmidt, +2 more
- 16 Oct 1987 - 
TL;DR: Data support the hypothesis that crucial variables for the expression of activity-dependent synaptic modifications are a critical level of postsynaptic activation and calcium entry through ion channels linked to NMDA receptors.
Journal ArticleDOI

Disruption of experience-dependent synaptic modifications in striate cortex by infusion of an NMDA receptor antagonist.

Mark F. Bear, +3 more
- 01 Mar 1990 - 
TL;DR: The data indicate that the effects of APV on kitten striate cortex are likely due specifically to the blockade of NMDA receptors, and lasting effects of chronic APV infusion were not observed in adult striates.
Journal ArticleDOI

Simultaneous recording of cerebral blood oxygenation changes during human brain activation by magnetic resonance imaging and near-infrared spectroscopy

Andreas Kleinschmidt, +6 more
- 01 Sep 1996 - 
TL;DR: Results underline the hitherto assumed signal physiology for functional brain mapping by oxygenation-sensitive MRI and allow assessment of both constraints and practicability of functional studies by NIRS.
