Aberrant age-related alterations in spontaneous cortical activity in participants with cerebral palsy

Frontiers in Neurology, 2023
IntroductionCerebral Palsy (CP) is the most common neurodevelopmental motor disability, resulting in life-long sensory, perception and motor impairments.

Testosterone modulates multispectral oscillatory activity serving performance of motor sequences in typically developing youth. [PDF]

J Physiol
Abstract figure legend Increases in testosterone are associated with developmental changes in motor‐related neural oscillations in youth. Abstract Motor control is critical to daily functioning and undergoes significant refinement throughout youth. Although the effects of age on the underlying brain circuitry have been well characterized, fewer studies

Unstable slow oscillations couple with epileptogenic fast‐rhythm bistability in sleep‐related epilepsy: A stereoelectroencephalographic study

Epilepsia, EarlyView.
We examined the functional relationship between large‐scale δ‐band phase synchrony and local epileptogenic β–γ‐band amplitude bistability during NREM sleep. Increased synchrony and strong bistability characterized the epileptogenic zone, with strongest effects during N2 sleep, when seizures most frequently occur.

Sleep magnetoencephalography enhances detection and source imaging of seizures and fast oscillations in focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) causes drug‐resistant epilepsy requiring presurgical evaluation. Invasive electroencephalographic (EEG) studies demonstrate that sleep modulates epileptic activity, including interictal epileptiform discharges (IEDs), fast oscillations (FOs) in the beta (14–40 Hz) and gamma (40–80 Hz) frequency bands ...

The effect of sensor-to-source distance on magnetic neuromuscular signals

Scientific Reports
Magnetomyography (MMG) can be used as a contactless modality to study the neuromuscular system. On the one hand, being contactless is a practical advantage as there is no need to prepare skin or attach electrodes as in electromyography (EMG).

Thalamic connectivity mirrors spatial maps of network dysfunction in nonlesional focal epilepsy

Epilepsia, EarlyView.
Abstract Objective Focal epilepsy is increasingly conceptualized as a network disorder, yet the extent to which network dysfunction reflects a shared phenotype remains unknown. Spatially conserved patterns of network dysfunction may implicate a centralized mechanism underlying widespread impairment.

Souvenaid in the Management of Mild Cognitive Impairment: An Expert Consensus Opinion [PDF]

, 2019
Background Mild cognitive impairment (MCI) among an aging global population is a growing challenge for healthcare providers and payers. In many cases, MCI is an ominous portent for dementia.

Performance of the 5‐SENSE score in a pediatric and young adult cohort of 100 consecutive stereoelectroencephalography cases

Epilepsia, EarlyView.
Abstract This study assesses the validity of the 5‐SENSE score in a cohort of pediatric patients with epilepsy and evaluates associations between the score, ancillary testing, and surgical outcomes. We retrospectively calculated the 5‐SENSE score in a single‐center predominantly pediatric cohort and calculated the sensitivity and specificity for ...

The Unique Determination of Neuronal Currents in the Brain via Magnetoencephalography

, 2004
The problem of determining the neuronal current inside the brain from measurements of the induced magnetic field outside the head is discussed under the assumption that the space occupied by the brain is approximately spherical.

Artificial intelligence for adaptive neuromodulation in drug‐resistant epilepsy

Epilepsia, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects nearly one third of people with epilepsy and is associated with substantial cognitive, psychiatric, and mortality burdens. For patients who are not candidates for resection or laser interstitial thermal therapy, neuromodulation therapies such as vagus nerve stimulation, deep brain stimulation, and ...
