Cell Type-Specific Long-Term Plasticity at Glutamatergic Synapses Onto Hippocampal Interneurons Expressing Either
The Journal of Neuroscience, January 27, 2010 • 30(4):1337–1347 • 1337 Behavioral/Systems/Cognitive Cell Type-Specific Long-Term Plasticity at Glutamatergic Synapses onto Hippocampal Interneurons Expressing either Parvalbumin or CB1 Cannabinoid Receptor Wiebke Nissen,1 Andras Szabo,1 Jozsef Somogyi,2 Peter Somogyi,2 and Karri P. Lamsa1 1Department of Pharmacology, Oxford University, Oxford OX1 3QT, United Kingdom, and 2Medical Research Council Anatomical Neuropharmacology Unit, Oxford University, Oxford OX1 3TH, United Kingdom Different GABAergic interneuron types have specific roles in hippocampal function, and anatomical as well as physiological features vary greatly between interneuron classes. Long-term plasticity of interneurons has mostly been studied in unidentified GABAergic cells and is known to be very heterogeneous. Here we tested whether cell type-specific plasticity properties in distinct GABAergic interneuron types might underlie this heterogeneity. We show that long-term potentiation (LTP) and depression (LTD), two common forms of synaptic plasticity, are expressed in a highly cell type-specific manner at glutamatergic synapses onto hippocampal GABAergic neurons. Both LTP and LTD are generated in interneurons expressing parvalbumin (PVϩ), whereas interneurons with similar axon distributions but expressing cannabinoid receptor-1 show no lasting plasticity in response to the same protocol. In addition, LTP or LTD occurs in PVϩ interneurons with different efferent target domains. Perisomatic-targeting PVϩ basket and axo-axonic interneurons express LTP, whereas glutamatergic synapses onto PVϩ bistratified cells display LTD. Both LTP and LTD are pathway specific, independent of NMDA receptors, and occur at synapses with calcium-permeable (CP) AMPA receptors. Plasticity in interneurons with CP-AMPA receptors strongly modulates disynaptic GABAergic transmission onto CA1 pyramidal cells. -

The Clinical and Genetic Heterogeneity of Paroxysmal Dyskinesias
doi:10.1093/brain/awv310 BRAIN 2015: 138; 3567–3580 | 3567 The clinical and genetic heterogeneity of paroxysmal dyskinesias Alice R. Gardiner,1,2 Fatima Jaffer,1,2 Russell C. Dale,3 Robyn Labrum,4 Roberto Erro,5 Esther Meyer,6 Georgia Xiromerisiou,2,7 Maria Stamelou,5,8,9 Matthew Walker,10 Dimitri Kullmann,10 Tom Warner,2 Paul Jarman,5 Mike Hanna,1 Manju A. Kurian,6,11 Kailash P. Bhatia5,* and Henry Houlden1,2,4,* Downloaded from ÃThese authors contributed equally to this work. Paroxysmal dyskinesia can be subdivided into three clinical syndromes: paroxysmal kinesigenic dyskinesia or choreoathetosis, paroxysmal exercise-induced dyskinesia, and paroxysmal non-kinesigenic dyskinesia. Each subtype is associated with the known http://brain.oxfordjournals.org/ causative genes PRRT2, SLC2A1 and PNKD, respectively. Although separate screening studies have been carried out on each of the paroxysmal dyskinesia genes, to date there has been no large study across all genes in these disorders and little is known about the pathogenic mechanisms. We analysed all three genes (the whole coding regions of SLC2A1 and PRRT2 and exons one and two of PNKD) in a series of 145 families with paroxysmal dyskinesias as well as in a series of 53 patients with familial episodic ataxia and hemiplegic migraine to investigate the mutation frequency and type and the genetic and phenotypic spectrum. We examined the mRNA expression in brain regions to investigate how selective vulnerability could help explain the phenotypes and analysed the effect of mutations on patient-derived mRNA. Mutations in the PRRT2, SLC2A1 and PNKD genes were identified in 72 families in the entire study. -
ICTALS2019 the Epilepsy Journey
ICTALS2019 The Epilepsy Journey 2-5 September In partnership with Abstract book This conference is supported by a grant from the American Epilepsy Society ICTALS2019 The Epilepsy Journey Foreword The International Conference for Technology and Analysis of Seizures, 2019 (ICTALS2019) aims to bring together neurologists, neuroscientists, researchers from quantitative disciplines and people with lived experience of epilepsy in order to work as a community to advance our understanding of epilepsy and develop practical ways to improve diagnosis and treatment. The theme for this year’s conference is: The Epilepsy Journey: from first seizure to treatment and beyond. We will emphasise how advances in our understanding of the dynamics of brain networks can be used to make a difference to people with epilepsy at all points of their journey: from elucidating the causes of the first seizure to diagnosing epilepsy, understanding how ictogenic networks give rise to recurrent seizures and how this insight can inform personalised treatment. To encourage this focus on the whole epilepsy journey we seek to include all relevant communities. In addition to discussions on current scientific, clinical and technological advances, we will take steps to increase accessibility for people with lived experience of epilepsy. Dates: Monday 2 September 2019 - Thursday 5 September 2019 Venue: University of Exeter, Streatham Campus, Xfi Building Conference website: http://ex.ac.uk/ictals2019 Contact the organisers: [email protected] ICTALS2019 The Epilepsy Journey Partners We are partnering with charities Epilepsy Research UK and Epilepsy Action and Alliance for Epilepsy Research. Sponsors This event would not be possible without the generous contributions from our generous sponsors UCB, the Epilepsy Foundation, NeuraLynx, and Liva Nova. -

As a scientific community we have entered an exciting therapeutic era, where advances in cell biology and animal models of CMT are paving the way for rational treatments and this has accelerated the need to improve our diagnostic rate and accuracy. Despite the discovery of more than 90 causative CMT genes through the advent and use of next-generation sequencing (NGS) technologies, there are still patients with specific subtypes of CMT, such as CMT2 and distal Hereditary Neuropathy (dHMN) that remain without a genetic diagnosis. Through the use of whole exome and whole genome sequencing, I endeavour to identify new pathogenic genetic variants of CMT and through functional assays and where possible transcriptomic analysis, study the effect of non-coding variants in the pathogenesis of CMT.

However its current use is restricted to specific electroencephalograph scenarios, namely in the diagnosis refractory focal epilepsies where electroencephalography (EEG) has been source localisation inconclusive. This review highlights the recent progress of MEG within epilepsy, including advances in the OPMs technique itself such as simultaneous EEG/MEG and intracranial EEG/MEG recording and room temperature MEG recording using optically pumped magnetometers, as well as improved post processing of the data during interictal and ictal activity for accurate source localisation of the epileptogenic focus. These advances should broaden the scope of MEG as an important part of epilepsy diagnostics in the future. 1. Introduction one large study of 1000 consecutive cases of refractory focal epilepsy demonstrated that MEG provided additional information to existing pre- A mainstay in epilepsy diagnostics over the last century has been the surgical methods (including scalp EEG, single photon emission electroencephalogram or EEG. Simply explained, EEG records electrical computed tomography (SPECT) and MRI) in 32% of cases, and complete currents reflecting synchronous neuronal activity attributable to the magnetoencephalography resection was associated with significantly brain surface, and can identify abnormal activity related to epilepsy with higher chances to achieve seizure freedom in the short and long-term good temporal resolution.
