Critical Changes in Cortical Neuronal Interactions in Anesthetized and Awake Rats [PDF]

, 2015
Background: Neuronal interactions are fundamental for information processing, cognition and consciousness. Anesthetics reduce spontaneous cortical activity; however, neuronal reactivity to sensory stimuli is often preserved or augmented.

Inroads into epilepsy through high‐frequency oscillations: Achievements and benchmark areas for improvement

Epilepsia, EarlyView.
Abstract High‐frequency oscillations (HFOs) were discovered more than 20 years ago, and since then they have been studied intensively in the context of epilepsy. HFOs encompass a broad spectrum of oscillations, typically ranging from 80 Hz to several kHz, that include both normal and pathological oscillations, documented in people with epilepsy and ...

Effects of social stimuli on sleep in mice: non-rapid-eye-movement (NREM) sleep is promoted by aggressive interaction but not by sexual interaction [PDF]

, 2001
Sleep is generally considered to be a process of recovery from prior wakefulness. In addition to being affected by the duration of the waking period, sleep architecture and sleep EEG also depend on the quality of wakefulness.

Deep characterization of refractory epilepsy due to mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE) and insights into the role of invasive monitoring

Epilepsia, EarlyView.
Abstract Objective Epilepsy surgery is an effective treatment option for patients with medically refractory epilepsy due to mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE). The success of surgery depends on the accurate localization of the epileptogenic zone, which can be challenging due to the subtle imaging ...

Fast cycle of vagus nerve stimulation is associated with increased sleep‐related breathing disorder in patients with epilepsy

Epilepsia, EarlyView.
Abstract Objective This work was undertaken to study the association between vagus nerve stimulation (VNS) parameters and the apnea–hypopnea index (AHI) measured by polysomnography in patients with drug‐resistant epilepsy. Methods Patients with epilepsy who underwent polysomnography with an active VNS device between 2018 and 2023 were retrospectively ...

Scale Invariance and Nonlinear Patterns of Human Activity [PDF]

, 2003
We investigate if known extrinsic and intrinsic factors fully account for the complex features observed in recordings of human activity as measured from forearm motion in subjects undergoing their regular daily routine. We demonstrate that the apparently

Bidirectional sleep‐seizure interactions and orexin in a mouse model of tuberous sclerosis complex‐related epilepsy

Epilepsia, EarlyView.
Abstract Objective A strong bidirectional relationship exists between epilepsy and sleep, with seizures often occurring more frequently in sleep and, in turn, sleep being disrupted by seizures. However, the mechanistic basis of seizure–sleep interactions is poorly understood.

Sleep-wake sensitive mechanisms of adenosine release in the basal forebrain of rodents : an in vitro study [PDF]

, 2013
Adenosine acting in the basal forebrain is a key mediator of sleep homeostasis. Extracellular adenosine concentrations increase during wakefulness, especially during prolonged wakefulness and lead to increased sleep pressure and subsequent rebound sleep.

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 ...
