Anti-seizure medication load is not correlated with early termination of seizure spread

Nathan Evans, Sarah J. Gascoigne, Guillermo M. Besne +11

Objective: Anti-seizure medications (ASMs) are the mainstay of treatment for epilepsy, yet their effect on seizure spread is not fully understood. Higher ASM doses have been associ…

Anti-seizure medication tapering correlates with daytime delta band power reduction in the cortex

Guillermo M. Besne, Nathan Evans, Mariella Panagiotopoulou +11

Anti-seizure medications (ASMs) are the primary treatment for epilepsy, yet medication tapering effects have not been investigated in a dose, region, and time-dependent manner, des…

Alpha rhythm slowing in temporal epilepsy across Scalp EEG and MEG

Vytene Janiukstyte, Csaba Kozma, Thomas W. Owen +8

EEG slowing is reported in various neurological disorders including Alzheimer's, Parkinson's and Epilepsy. Here, we investigate alpha rhythm slowing in individuals with refractory…

Multi-centre normative brain mapping of intracranial EEG lifespan patterns in the human brain

Heather Woodhouse, Gerard Hall, Callum Simpson +18

Background: Understanding healthy human brain function is crucial to identify and map pathological tissue within it. Whilst previous studies have mapped intracranial EEG (icEEG) fr…

Incomplete resection of the icEEG seizure onset zone is not associated with post-surgical outcomes

Sarah J. Gascoigne, Nathan Evans, Gerard Hall +16

Delineation of seizure onset regions from EEG is important for effective surgical workup. However, it is unknown if their complete resection is required for seizure freedom, or in…

Aperiodic MEG abnormality in patients with focal to bilateral tonic-clonic seizures

Kirandeep Kaur, Jonathan J Horsley, Csaba Kozma +7

Aperiodic activity is a physiologically distinct component of the electrophysiological power spectrum. It is suggested to reflect the balance of excitation and inhibition in the br…

Identifying epileptogenic abnormality by decomposing intracranial EEG and MEG power spectra

Csaba Kozma, Gabrielle Schroeder, Tom Owen +6

Identifying abnormal electroencephalographic activity is crucial in diagnosis and treatment of epilepsy. Recent studies showed that decomposing brain activity into periodic (oscill…

Diminished circadian and ultradian rhythms of human brain activity in pathological tissue in vivo

Christopher Thornton, Mariella Panagiotopoulou, Fahmida A Chowdhury +10

Chronobiological rhythms, such as the circadian rhythm, have long been linked to neurological disorders, but it is currently unknown how pathological processes affect the expressio…

Interictal MEG abnormalities to guide intracranial electrode implantation and predict surgical outcome

Thomas W. Owen, Vytene Janiukstyte, Gerard R. Hall +9

Intracranial EEG (iEEG) is the gold standard technique for epileptogenic zone (EZ) localisation, but requires a hypothesis of which tissue is epileptogenic, guided by qualitative a…

Identifying epileptogenic abnormalities through spatial clustering of MEG interictal band power

Thomas W. Owen, Vytene Janiukstyte, Gerard R. Hall +8

Successful epilepsy surgery depends on localising and resecting cerebral abnormalities and networks that generate seizures. Abnormalities, however, may be widely distributed across…

Normative brain mapping using scalp EEG and potential clinical application

Vytene Janiukstyte, Thomas W Owen, Umair J Chaudhary +6

A normative electrographic activity map could be a powerful resource to understand normal brain function and identify abnormal activity. Here, we present a normative brain map usin…

Complementary structural and functional abnormalities to localise epileptogenic tissue

Jonathan J Horsley, Rhys H Thomas, Fahmida A Chowdhury +10

When investigating suitability for surgery, people with drug-refractory focal epilepsy may have intracranial EEG (iEEG) electrodes implanted to localise seizure onset. Diffusion-we…

Temporal stability of intracranial EEG abnormality maps for localising epileptogenic tissue

Yujiang Wang, Gabrielle M Schroeder, Jonathan J Horsley +8

Objective: Identifying abnormalities in interictal intracranial EEG, by comparing patient data to a normative map, has shown promise for the localisation of epileptogenic tissue an…

Effects of anterior temporal lobe resection on cortical morphology

Karoline Leiberg, Jane de Tisi, John S Duncan +6

Anterior temporal lobe resection (ATLR) is a surgical procedure to treat drug-resistant temporal lobe epilepsy (TLE). Resection may involve large amounts of cortical tissue. Here,…

Neuro-evolutionary evidence for a universal fractal primate brain shape

Yujiang Wang, Karoline Leiberg, Nathan Kindred +5

The cerebral cortex displays a bewildering diversity of shapes and sizes across and within species. Despite this diversity, we present a universal multi-scale description of primat…

MEG abnormalities and mechanisms of surgical failure in neocortical epilepsy

Thomas W. Owen, Gabrielle M. Schroeder, Vytene Janiukstyte +8

Neocortical epilepsy surgery fails to achieve post-operative seizure freedom in 30-40% of cases. It is not fully understood why surgery in some patients is unsuccessful. Comparing…

A library of quantitative markers of seizure severity

Sarah J. Gascoigne, Leonard Waldmann, Mariella Panagiotopoulou +16

Purpose: Understanding fluctuations of seizure severity within individuals is important for defining treatment outcomes and response to therapy, as well as developing novel treatme…
