The brain is a dynamic, flexible network that continuously reconfigures. However, the neural underpinnings of how state-dependent variability of dynamic functional connectivity (vdFC) relates to cognitive flexibility are unclear. We therefore investigated flexible functional connectivity during resting-state and task-state functional magnetic resonance imaging (rs-fMRI and t-fMRI, resp.) and pe...

results trail making test part b cognitive test showed statistically significant in comparison for pre and post exposure of anesthetics. this difference was seen in the desflurane group. other cognitive tests did not show differences on exposure to the anesthetic gases. conclusions this study questioned the difference between volatile anesthetic agent’s effects on patients completing a battery ...

Our study focuses on mood induction with pleasant and unpleasant auditory stimuli during the break. Our test includes subjective evaluation (NASA-TLX, KSS, POMS), cognitive tests and brain responses (MEG and EEG). We aim studying the effect affective state has on work-like tasks. Hypothesis: pleasantness of auditory mood induction affects cognitive performance and brain responses.

Background: Hypothermia is usually used during cardiac surgery to further protect against cardiac and cerebral ischemia. However, cognitive impairment could be a common complication after open heart surgery. This study aims to determine the effect of rewarming on the cognitive status of patients after open heart surgery.  Methods: The present study was conducted as a double-blind, randomized c...

Background: The prevalence and incidence of dementia increase dramatically with age. Cognitive impairment is one major symptom of dementia. Older persons increase in our society, which means a big number of people with decreased cognitive function. So it is important to find out risk factors. The amino acid homocysteine may be a risk factor. Objective: The aim was to determine the independent a...

The drawing figures are widely managed as an ideal instrument for self-expression. HFD test (Human Figure Drawing) is an abbreviated test which was developed with the aim to evaluate various psychological states, especially assessing the psychic status including psychiatric illness and personality state. Thus, the reliance on the drawings must be proven that it has no bias due to cognitive diff...
