Modeling the contribution of theta-gamma coupling to sequential memory, imagination, and dreaming

Frontiers in Neural Circuits
Gamma oscillations nested in a theta rhythm are observed in the hippocampus, where are assumed to play a role in sequential episodic memory, i.e., memorization and retrieval of events that unfold in time.

The olfactory bulb theta rhythm follows all frequencies of diaphragmatic respiration in the freely behaving rat

Frontiers in Behavioral Neuroscience, 2014
Sensory-motor relationships are part of the normal operation of sensory systems. Sensing occurs in the context of active sensor movement, which in turn influences sensory processing. We address such a process in the rat olfactory system.

Spectral entropy variability of intraoperative electrocorticography predicts outcome after epilepsy surgery in people with focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Epilepsy surgery in people with focal cortical dysplasia (FCD) requires accurate removal of all epileptogenic tissue, and outcome is difficult to predict. We explored whether spectral entropy, a fast computable electroencephalographic (EEG) feature, could estimate epileptic activity in intraoperative electrocorticography (ioECoG) and

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 ...

Rhythms in longitudinal thalamic recordings are linked to seizure risk

Epilepsia, EarlyView.
Abstract Objective Seizure unpredictability remains a major clinical challenge for people with epilepsy. Previous works have shown that seizure risk is associated with circadian and multi‐day cycles in both brain and physiological signals. However, it remains unclear whether neural activity from deep brain structures such as the anterior nucleus of the

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.

The medial entorhinal cortex is necessary for temporal organization of hippocampal neuronal activity. [PDF]

, 2015
The superficial layers of the medial entorhinal cortex (MEC) are a major input to the hippocampus. The high proportion of spatially modulated cells, including grid cells and border cells, in these layers suggests that MEC inputs are critical for the ...

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.
