Spike firing and IPSPs in layer V pyramidal neurons during beta oscillations in rat primary motor cortex (M1) in vitro.

open access: yesPLoS ONE, 2014
Beta frequency oscillations (10-35 Hz) in motor regions of cerebral cortex play an important role in stabilising and suppressing unwanted movements, and become intensified during the pathological akinesia of Parkinson's Disease.

Decoding gripping force based on local field potentials recorded from subthalamic nucleus in humans

open access: yeseLife, 2016
The basal ganglia are known to be involved in the planning, execution and control of gripping force and movement vigour. Here we aim to define the nature of the basal ganglia control signal for force and to decode gripping force based on local field ...

Neuronal biomarkers of Parkinson's disease are present in healthy aging

open access: yesNeuroImage, 2021
The prevalence of Parkinson's disease (PD) increases with aging and both processes share similar cellular mechanisms and alterations in the dopaminergic system.

Beta oscillations relate to the N400m during language comprehension [PDF]

open access: yesHuman Brain Mapping, 2012
AbstractThe relationship between the evoked responses (ERPs/ERFs) and the event‐related changes in EEG/MEG power that can be observed during sentence‐level language comprehension is as yet unclear. This study addresses a possible relationship between MEG power changes and the N400m component of the event‐related field. Whole‐head MEG was recorded while

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Perturbation Theory of Neutrino Oscillation with Nonstandard Neutrino Interactions

open access: yes, 2009
We discuss various physics aspects of neutrino oscillation with non-standard interactions (NSI). We formulate a perturbative framework by taking \Delta m^2_{21} / \Delta m^2_{31}, s_{13}, and the NSI elements \epsilon_{\alpha \beta} (\alpha, \beta = e ...

Membrane resonance enables stable and robust gamma oscillations [PDF]

open access: yes, 2012
Neuronal mechanisms underlying beta/gamma oscillations (20-80 Hz) are not completely understood. Here, we show that in vivo beta/gamma oscillations in the cat visual cortex sometimes exhibit remarkably stable frequency even when inputs fluctuate ...

Alterations in Brain Connectivity Underlying Beta Oscillations in Parkinsonism

open access: yesPLoS Computational Biology, 2011
Cortico-basal ganglia-thalamocortical circuits are severely disrupted by the dopamine depletion of Parkinson's disease (PD), leading to pathologically exaggerated beta oscillations. Abnormal rhythms, found in several circuit nodes are correlated with movement impairments but their neural basis remains unclear.

Repetitive Passive Finger Movement Modulates Primary Somatosensory Cortex Excitability

open access: yesFrontiers in Human Neuroscience, 2018
Somatosensory inputs induced by repetitive passive movement (RPM) modulate primary motor cortex (M1) excitability; however, it is unclear whether RPM affects primary somatosensory cortex (S1) excitability.
