Disrupted neural variability during propofol‐induced sedation and unconsciousness
(John Wiley & Sons, Inc., 2018-11)
Variability quenching is a widespread neural phenomenon in which trial‐to‐trial variability (TTV) of neural activity is reduced by repeated presentations of a sensory stimulus. However, its neural mechanism and functional ...
Evaluating the arcuate fasciculus with combined diffusion‐weighted MRI tractography and electrocorticography
(Wiley Periodicals, Inc.Helsinki University of Technology, 2014-05)
The conventional model of language‐related brain structure describing the arcuate fasciculus as a key white matter tract providing a direct connection between Wernicke's region and Broca's area has been called into question. ...
Evidence that neurovascular coupling underlying the BOLD effect increases with age during childhood
(SaundersWiley Periodicals, Inc., 2015-01)
Functional MRI using blood–oxygen‐level‐dependent (BOLD) imaging has provided unprecedented insights into the maturation of the human brain. Task‐based fMRI studies have shown BOLD signal increases with age during development ...
White matter developmental trajectories associated with persistence and recovery of childhood stuttering
(Thomson Delmar LearningWiley Periodicals, Inc., 2017-07)
Stuttering affects the fundamental human ability of fluent speech production, and can have a significant negative impact on an individual’s psychosocial development. While the disorder affects about 5% of all preschool ...
The South Africa Stress and Health Study: Rationale and Design
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2004-06)
The South Africa Stress and Health Study (SASH) is a large psychiatric epidemiological survey that is currently underway in South Africa. It is a part of the World Health Organization's World Mental Health (WMH) 2000 ...
Toward a “treadmill test” for cognition: Improved prediction of general cognitive ability from the task activated brain
(John Wiley & Sons, Inc., 2020-08-15)
General cognitive ability (GCA) refers to a trait‐like ability that contributes to performance across diverse cognitive tasks. Identifying brain‐based markers of GCA has been a longstanding goal of cognitive and clinical ...
Spontaneous and visually driven high‐frequency oscillations in the occipital cortex: Intracranial recording in epileptic patients
(Wiley Subscription Services, Inc., A Wiley Company, 2012-03)
High‐frequency oscillations (HFOs) at ≥80 Hz of nonepileptic nature spontaneously emerge from human cerebral cortex. In 10 patients with extraoccipital lobe epilepsy, we compared the spectral‐spatial characteristics of ...
Cortical gamma-oscillations modulated by auditory–motor tasks-intracranial recording in patients with epilepsy
(Wiley Subscription Services, Inc., A Wiley Company, 2010-11)
Human activities often involve hand-motor responses following external auditory–verbal commands. It has been believed that hand movements are predominantly driven by the contralateral primary sensorimotor cortex, whereas ...
Functional magnetic resonance imaging multivoxel pattern analysis reveals neuronal substrates for collaboration and competition with myopic and predictive strategic reasoning
(John Wiley & Sons, Inc., 2020-10-15)
Competition and collaboration are strategies that can be used to optimize the outcomes of social interactions. Research into the neuronal substrates underlying these aspects of social behavior has been limited due to the ...
Cortical glucose metabolism correlates negatively with delta-slowing and spike-frequency in epilepsy associated with tuberous sclerosis
(Wiley Subscription Services, Inc., A Wiley Company, 2008-11)
The mechanism of altered glucose metabolism seen on positron emission tomography (PET) in focal epilepsy is not fully understood. We determined the association between interictal glucose metabolism and interictal neuronal ...
