Detecting sub-second changes in brain activation patterns during interictal epileptic spike using simultaneous EEG-fMRI

OBJECTIVE Epileptic spikes are associated with rapidly changing brain activation involving the epileptic foci and other brain regions in the "epileptic network". We aim to resolve these activation changes using simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) recordings. METHODS Simultaneous EEG-fMRI recordings from 9 patients with epilepsy were used ...

Coherent EEG indicators of cognitive binding during ambiguous figure tasks.

We tested the hypothesis that perception of an alternative image in ambiguous figures would be manifest as high-frequency (gamma) components that become synchronized over multiple scalp sites as a "cognitive binding" process occurs. For 171 combinations of data from 19 electrodes, obtained from 17 subjects and 10 replicate stimuli, we calculated the difference in correlation between the respons...

Tracking dynamics of functional brain networks using dense EEG

Cognition is formed from networks between functionally specific but distributed brain regions. A very challenging issue in cognition is how to precisely track brain networks at very short temporal scales (often very short <1s). So far, very few studies have addressed this problem as it requires high temporal and spatial resolution simultaneously. Due to its excellent temporal resolution, Electr...

Cognitive levels and Software Maintenance Sub-tasks

This paper describes a case study that was carried out to characterize the behaviour of professional programmers, working on in-vivo software maintenance tasks, in terms of the cognitive levels of Bloom’s taxonomy. Specifically, it evaluates if their behaviour on specific maintenance sub-tasks can be associated with specific cognitive levels of the taxonomy. The findings suggest that some such ...

Males and females differ in brain activation during cognitive tasks.

To examine the effect of gender on regional brain activity, we utilized functional magnetic resonance imaging (fMRI) during a motor task and three cognitive tasks; a word generation task, a spatial attention task, and a working memory task in healthy male (n = 23) and female (n = 10) volunteers. Functional data were examined for group differences both in the number of pixels activated, and the ...
