Magnetoencephalography for Schizophrenia

Neuroimaging Clinics of North America, 2020
Schizophrenia (Sz) is a chronic mental disorder characterized by disturbances in thought (such as delusions and confused thinking), perception (hearing voices), and behavior (lack of motivation). The lifetime prevalence of Sz is between 0.3% and 0.7%, with late adolescence and early adulthood, the peak period for the onset of psychotic symptoms. Causal

Dynamic filtering of static dipoles in magnetoencephalography [PDF]

, 2013
We consider the problem of estimating neural activity from measurements of the magnetic fields recorded by magnetoencephalography. We exploit the temporal structure of the problem and model the neural current as a collection of evolving current ...

Magnetoencephalography as a putative biomarker for Alzheimer's disease. [PDF]

, 2011
Alzheimer’s Disease (AD) is the most common dementia in the elderly and is estimated to affect tens of millions of people worldwide. AD is believed to have a prodromal stage lasting ten or more years.

Magnetoencephalography and normal pressure hydrocephalus: A case report [PDF]

Journal of Integrative Neuroscience, 2018
In a case study of an 82-year old male spontaneous magnetoencephalography recordings revealed lower magnetic fields at frontal and frontotemporal regions compared to central and posterior regions.

Cortical correlation structure of aperiodic neuronal population activity

NeuroImage, 2021
Electrophysiological population signals contain oscillatory and non-oscillatory aperiodic (1/frequency-like) components. So far research has largely focused on oscillatory activity, and only recently, interest in aperiodic population activity has gained ...

The lifespan trajectory of neural oscillatory activity in the motor system

Developmental Cognitive Neuroscience, 2018
Numerous studies connect beta oscillations in the motor cortices to volitional movement, and beta is known to be aberrant in multiple movement disorders.

Response certainty during bimanual movements reduces gamma oscillations in primary motor cortex

NeuroImage, 2021
Even when movement outputs are identical, the neural responses supporting them might differ substantially in order to adapt to changing environmental contexts.

Activation of the left inferior frontal gyrus in the first 200 ms of reading: evidence from magnetoencephalography (MEG) [PDF]

, 2009
BACKGROUND: It is well established that the left inferior frontal gyrus plays a key role in the cerebral cortical network that supports reading and visual word recognition. Less clear is when in time this contribution begins.

Development and sex modulate visuospatial oscillatory dynamics in typically-developing children and adolescents

NeuroImage, 2020
Visuospatial processing is a cognitive function that is critical to navigating one's surroundings and begins to develop during infancy. Extensive research has examined visuospatial processing in adults, but far less work has investigated how visuospatial
