The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Role of beta-band resting-state functional connectivity as a predictor of motor learning ability

NeuroImage, 2020
It has been suggested that resting-state functional connectivity (rs-FC) between the primary motor area (M1) region of the brain and other brain regions may be a predictor of motor learning, although this suggestion is still controversial.

Global efficiency of the motor network is decreased in Parkinson's disease in comparison with essential tremor and healthy controls

Brain and Behavior, 2021
Background Graph theory (GT) is a mathematical field that analyses complex networks that can be applied to neuroimaging to quantify brain's functional systems in Parkinson's disease (PD) and essential tremor (ET).

Differences in motor network dynamics during recovery between supra‐ and infra‐tentorial ischemic strokes

Human Brain Mapping, 2018
Most previous stroke studies have been performed in heterogeneous patient populations. Moreover, the brain network might demonstrate different recovery dynamics according to lesion location.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

In vitro biocompatibility evaluation of functional electrically stimulating microelectrodes on primary glia

Frontiers in Bioengineering and Biotechnology
Neural interfacing devices interact with the central nervous system to alleviate functional deficits arising from disease or injury. This often entails the use of invasive microelectrode implants that elicit inflammatory responses from glial cells and ...

Coupling of Active Motion and Advection Shapes Intracellular Cargo Transport

, 2012
Intracellular cargo transport can arise from passive diffusion, active motor-driven transport along cytoskeletal filament networks, and passive advection by fluid flows entrained by such motor/cargo motion.

A combined diffusion‐weighted and electroencephalography study on age‐related differences in connectivity in the motor network during bimanual performance

Human Brain Mapping, 2018
We studied the relationship between age‐related differences in inter‐ and intra‐hemispheric structural and functional connectivity in the bilateral motor network.

Motor Recovery After Subcortical Stroke Depends on Modulation of Extant Motor Networks [PDF]

Frontiers in Neurology, 2015
Stroke is the leading cause of long-term disability. Functional imaging studies report widespread changes in movement-related cortical networks after stroke. Whether these are a result of stroke-specific cognitive processes or reflect modulation of existing movement-related networks is unknown. Understanding this distinction is critical in establishing
