The neurophysiology of closed-loop auditory stimulation in sleep: A magnetoencephalography study

Author(s): Jourde HR; Merlo R; Brooks M; Rowe M; Coffey EBJ;

Closed-loop auditory stimulation (CLAS) is a brain modulation technique in which sounds are timed to enhance or disrupt endogenous neurophysiological events. CLAS of slow oscillation up-states in sleep is becoming a popular tool to study and enhance sleep&# ...

Neurophysiology, Neuropsychology, and Epilepsy, in 2022: Hills We Have Climbed and Hills Ahead. Neurophysiology in epilepsy

Author(s): Frauscher B; Bénar CG; Engel JJ; Grova C; Jacobs J; Kahane P; Wiebe S; Zjilmans M; Dubeau F; ...

Since the discovery of the human electroencephalogram (EEG), neurophysiology techniques have become indispensable tools in our armamentarium to localize epileptic seizures. New signal analysis tech ...

Slow oscillation-spindle cross-frequency coupling predicts overnight declarative memory consolidation in older adults

Author(s): Oren M Weiner

Cross-frequency coupling (CFC) between brain oscillations during non-rapid-eye-movement (NREM) sleep (e.g. slow oscillations [SO] and spindles) may be a neural mechanism of overnight memory consolidation. Declines in CFC across the lifespan might accompany ...

Sigma oscillations protect or reinstate motor memory depending on their temporal coordination with slow waves

Author(s): Nicolas J; King BR; Levesque D; Lazzouni L; Coffey EBJ; Swinnen S; Doyon J; Carrier J; Albouy G; ...

Targeted memory reactivation (TMR) during post-learning sleep is known to enhance motor memory consolidation but the underlying neurophysiological processes remain unclear. Here, we confirm the ben ...

How cerebral cortex protects itself from interictal spikes: The alpha/beta inhibition mechanism

Author(s): Pellegrino G; Hedrich T; Sziklas V; Lina JM; Grova C; Kobayashi E;

Interactions between interictal epileptiform discharges (IEDs) and distant cortical regions subserve potential effects on cognition of patients with focal epilepsy. We hypothesize that "healthy" brain areas at a distance from the epileptic focus may respond ...

Using Models to (Re-)Design Synthetic Circuits.

Author(s): McCallum G, Potvin-Trottier L

Mathematical models play an important role in the design of synthetic gene circuits, by guiding the choice of biological components and their assembly into novel gene networks. Here, we present a guide for biologists to build and utilize models of gene netw ...

Cerebellar Cortex 4-12 Hz Oscillations and Unit Phase Relation in the Awake Rat.

Author(s): Lévesque M; Gao H; Southward C; Langlois JMP; Léna C; Courtemanche R;

Oscillations in the granule cell layer (GCL) of the cerebellar cortex have been related to behavior and could facilitate communication with the cerebral cortex. These local field potential (LFP) oscillations, strong at 4-12 Hz in the rodent cerebellar corte ...

Sleep spindles may predict response to cognitive-behavioral therapy for chronic insomnia

Author(s): Dang-Vu TT; Hatch B; Salimi A; Mograss M; Boucetta S; O' Byrne J; Brandewinder M; Berthomier C; Gouin JP; ...

Background: While cognitive-behavioral therapy for insomnia constitutes the first-line treatment for chronic insomnia, only few reports have investigated how sleep architecture relates to response ...
