Resting state fast brain dynamics predict interindividual variability in motor performance

Scientific Reports, 2022
Motor learning features rapid enhancement during practice then offline post-practice gains with the reorganization of related brain networks. We hypothesised that fast transient, sub-second variations in magnetoencephalographic (MEG) network activity ...

Cerebrovascular Reactivity Assays Collateral Function in Carotid Stenosis

Frontiers in Physiology, 2020
In patients with carotid artery stenosis (CAS), the risk of stroke, its severity, and response to revascularization are strongly related to the availability of collateral blood flow.

What happens to the inhibitory control functions of the right inferior frontal cortex when this area is dominant for language?

eLife
A low number of individuals show an atypical brain control of language functions that differs from the typical lateralization in the left cerebral hemisphere.

mTOR-related synaptic pathology causes autism spectrum disorder-associated functional hyperconnectivity

Nature Communications, 2021
Autism spectrum disorder (ASD) is characterised by synaptic surplus and atypical functional connectivity. Here, the authors show that synaptic pathology in Tsc2 haploinsufficient mice is associated with autism-like behavior and cortico-striatal ...

Engagement of Language and Domain General Networks during Word Monitoring in a Native and Unknown Language

Brain Sciences, 2021
Functional neuroimaging studies have highlighted the roles of three networks in processing language, all of which are typically left-lateralized: a ventral stream involved in semantics, a dorsal stream involved in phonology and speech production, and a ...

The Impact of Tilburg Frailty on Poststroke Fatigue in First‐Ever Stroke Patients: A Cross‐Sectional Study With Unified Measurement Tools and Improved Statistics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Poststroke fatigue (PSF) and frailty share substantial overlap in their manifestations, yet previous research has yielded conflicting results due to the use of heterogeneous frailty assessment tools. Objective To evaluate the independent impact of frailty on PSF using a unified measurement system (Tilburg Frailty Indicator, TFI ...

Neuroanatomical correlates of musicianship in left-handers

Behavioral and Brain Functions
Background Left-handedness is a condition that reverses the typical left cerebral dominance of motor control to an atypical right dominance. The impact of this distinct control — and its associated neuroanatomical peculiarities — on other cognitive ...

Functional neuroimaging in psychiatry [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1999
Functional neuroimaging is one of the most powerful means available for investigating the pathophysiology of psychiatric disorders. In this review, we shall focus on the different ways that it can be employed to this end, describing the major findings in the field in the context of different methodological approaches.
