Sleep spindles: mechanisms and functions

LMJ Fernandez, A Lüthi - Physiological reviews, 2020 - journals.physiology.org
Sleep spindles are burstlike signals in the electroencephalogram (EEG) of the sleeping
mammalian brain and electrical surface correlates of neuronal oscillations in thalamus. As …

Clinical and experimental insight into pathophysiology, comorbidity and therapy of absence seizures

V Crunelli, ML Lőrincz, C McCafferty, RC Lambert… - Brain, 2020 - academic.oup.com
Absence seizures in children and teenagers are generally considered relatively benign
because of their non-convulsive nature and the large incidence of remittance in early …

Maladaptive myelination promotes generalized epilepsy progression

JK Knowles, H Xu, C Soane, A Batra, T Saucedo… - Nature …, 2022 - nature.com
Activity-dependent myelination can fine-tune neural network dynamics. Conversely, aberrant
neuronal activity, as occurs in disorders of recurrent seizures (epilepsy), could promote …

Impaired cortico-striatal excitatory transmission triggers epilepsy

H Miyamoto, T Tatsukawa, A Shimohata… - Nature …, 2019 - nature.com
Abstract STXBP1 and SCN2A gene mutations are observed in patients with epilepsies,
although the circuit basis remains elusive. Here, we show that mice with haplodeficiency for …

EEG-fMRI in awake rat and whole-brain simulations show decreased brain responsiveness to sensory stimulations during absence seizures

P Stenroos, I Guillemain, F Tesler, O Montigon… - Elife, 2024 - elifesciences.org
In patients suffering absence epilepsy, recurring seizures can significantly decrease their
quality of life and lead to yet untreatable comorbidities. Absence seizures are characterized …

Decreased but diverse activity of cortical and thalamic neurons in consciousness-impairing rodent absence seizures

C McCafferty, BF Gruenbaum, R Tung, JJ Li… - Nature …, 2023 - nature.com
Absence seizures are brief episodes of impaired consciousness, behavioral arrest, and
unresponsiveness, with yet-unknown neuronal mechanisms. Here we report that an awake …

Thalamocortical circuits in generalized epilepsy: Pathophysiologic mechanisms and therapeutic targets

BE Lindquist, C Timbie, Y Voskobiynyk, JT Paz - Neurobiology of disease, 2023 - Elsevier
Generalized epilepsy affects 24 million people globally; at least 25% of cases remain
medically refractory. The thalamus, with widespread connections throughout the brain, plays …

A novel cortico-intrathalamic circuit for flight behavior

P Dong, H Wang, XF Shen, P Jiang, XT Zhu, Y Li… - Nature …, 2019 - nature.com
Flight, an active fear response to imminent threat, is dependent on the rapid risk assessment
of sensory information processed by the cortex. The thalamic reticular nucleus (TRN) filters …

[HTML][HTML] HCN channels and absence seizures

V Crunelli, F David, TP Morais, ML Lorincz - Neurobiology of Disease, 2023 - Elsevier
Hyperpolarization-activation cyclic nucleotide-gated (HCN) channels were for the first time
implicated in absence seizures (ASs) when an abnormal I h (the current generated by these …

[HTML][HTML] Gut microbiome effects on neuronal excitability & activity: Implications for epilepsy

H Darch, CP McCafferty - Neurobiology of disease, 2022 - Elsevier
It is now well established that the bacterial population of the gastrointestinal system, known
as the gut microbiome, is capable of influencing the brain and its dependent functions. Links …
