    The impact of pathological high-frequency oscillations on hippocampal network activity in rats with chronic epilepsy

    Laura A Ewell, Kyle B Fischer ... Jill K Leutgeb
    A novel framework for separating normal and pathological high-frequency oscillations in animals with epilepsy uncovers new mechanisms for impaired hippocampal network function.
    1. Neuroscience

    Mouse models of human PIK3CA-related brain overgrowth have acutely treatable epilepsy

    Achira Roy, Jonathan Skibo ... Kathleen J Millen
    Acute one-hour treatment of Pik3ca mutant mice with a novel anti-epilepsy drug suppresses seizures despite continued developmental brain dysmorphology, promising a new therapeutic strategy for patients with intractable pediatric epilepsy.
    1. Neuroscience

    Prefrontal PV interneurons facilitate attention and are linked to attentional dysfunction in a mouse model of absence epilepsy

    Brielle Ferguson, Cameron Glick, John R Huguenard
    Targeting reductions in prefrontal PV interneuron activity and gamma power during cue presentation can rescue attention impairments in a mouse model of absence epilepsy.
    1. Neuroscience

    Early tissue damage and microstructural reorganization predict disease severity in experimental epilepsy

    Philipp Janz, Niels Schwaderlapp ... Carola A Haas
    Non-invasive imaging of hippocampal neurodegeneration and structural reorganization during epileptogenesis allows the prediction of disease severity in mesial temporal lobe epilepsy, which may facilitate the early pharmacological intervention before seizure onset.
    1. Neuroscience

    Predictive models for secondary epilepsy in patients with acute ischemic stroke within one year

    Jinxin Liu, Haoyue He ... Yongbing Deng
    Machine learning models effectively predict the risk of post-stroke epilepsy using extensive clinical data, offering new insights for improving patient management in clinical neurology.

    EFHC1, implicated in juvenile myoclonic epilepsy, functions at the cilium and synapse to modulate dopamine signaling

    Catrina M Loucks, Kwangjin Park ... Michel R Leroux
    C. elegans EFHC1 influences neuronal transmission through the cilium and the synapse.
    1. Neuroscience

    Hippocampal low-frequency stimulation prevents seizure generation in a mouse model of mesial temporal lobe epilepsy

    Enya Paschen, Claudio Elgueta ... Carola A Haas
    Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.
    1. Neuroscience

    Increasing adult-born neurons protects mice from epilepsy

    Swati Jain, John J LaFrancois ... Helen E Scharfman
    Increasing adult-born neurons in the dentate gyrus reduces neuronal loss and chronic seizures in female mice using a mouse model of temporal lobe epilepsy.
    1. Neuroscience

    Hyperactivity of mTORC1- and mTORC2-dependent signaling mediates epilepsy downstream of somatic PTEN loss

    Erin R Cullen, Mona Safari ... Matthew C Weston
    Epilepsy caused by focal Pten deletion is only prevented when both mTOR complexes are simultaneously inhibited, but not alone, suggesting they play independent roles in the development of epilepsy.

    Structural determinants of adhesion by Protocadherin-19 and implications for its role in epilepsy

    Sharon R Cooper, James D Jontes, Marcos Sotomayor
    Structural and binding studies provide insight into the molecular mechanism of protocadherin-19-mediated adhesion and into the biochemical basis of neurodevelopmental disease.
