We are excited to launch a brand new webinar initiative, the MEGIN Masterclass, featuring an array of Key Opinion and Thought Leaders in the field. Each webinar will focus on a different topic, offering an opportunity to learn in more detail about the latest research and clinical cases. This will be a great forum to learn from some of the best minds in MEG, with time for questions, to connect with specialists and the wider, global community.
*All Masterclasses are subject to change

Understanding how pre- and post-natal exposures influence brain development using MEG
This MEGIN Masterclass presented by Dr. Julia Stephen will discuss how, “the brain develops rapidly throughout gestation and childhood. However, little is known about how pre- and post-natal exposures impact brain development in children. Our work has focused on examining how rearing environment and prenatal exposures impact brain development using MEG. MEG is especially well-suited for studying children across the age range because it is silent and requires minimal participant preparation time. Rearing environment, including socioeconomic status and maternal factors, influences brain development as revealed by delayed evoked responses and altered neural oscillations. These results indicate rearing environment needs to be accounted for in future studies to better understand human brain development in health and disease.”

Quantum leap: How hardware and software leaders MEGIN and BESA combined their strengths to streamline MEG analysis
MEG/EEG software pioneers BESA have partnered with MEGIN to bring their advanced software tools and data analysis experience together. For the first time, MEG data acquisition and analysis workflows enable the user to lift the treasures that lie hidden in the MEG signals with ease. This masterclass episode will look beyond the surface of the new epilepsy analysis workflow and discuss some of the innovations that blend into the new user experience.
*The referred software are works in progress.

Intricacies and misconceptions of Frontal Lobe Epilepsy
This masterclass presented by Dr. Saleem Malik will address the exquisite intricacies of frontal lobe epilepsy, which often can be misdiagnosed as sleep or psychiatric disorder. We shall start with review of peculiarities of craniocerebral anatomy of frontal lobe which represents 40% of total cortical volume. Particular attention will be paid to sub lobar areas which are either buried in cortex or strategically located away from convexity of brain where EEG electrodes are placed. We shall look into why semiological and electrical patterns of frontal lobe epilepsy often lack localizing and lateralizing features, contributing to relatively poor surgical outcomes? We shall review the role of Magnetic Source Imaging and see how higher spatio-temporal resolution of MSI complements Stereo EEG to delineate more accurately three dimension view of seizure propagation. At the end, we shall review few clinical cases and see how MSI is affecting lives of patients in real time.

Using MEG to study health and unhealthy ageing
This Masterclass presented by Rik Henson will discuss the Cambridge Centre for Aging and Neuroscience’s CamCAN dataset. This is one of the largest open-access datasets, which includes MEG data collected on nearly 700 adults ranging from 18-88 years. We will discuss a study of how age-related slowing of task-related evoked responses in sensory cortices is mediated by changes in both grey-matter and white-matter, and how resting-state MEG reveals age-related changes in brief microstates (lasting a few hundred milliseconds) that relate to cognition. The session will also cover the BioFIND dataset of resting-state MEG data on 324 people, and how MEG offers complimentary information beyond MRI in distinguishing healthy ageing from Mild Cognitive Impairment (MCI), a prodromal state of Alzheimer’s Disease.

Guidelines and practical considerations for language mapping in clinical cohorts using magnetoencephalography (MEG)
This Masterclass presented by Dr. Roozbeh Rezaie will discuss how since it’s adoption in clinical practice, much progress has been made in developing and optimizing MEG as a non-invasive tool for localizing language-specific cortex and determining hemispheric dominance for language, particularly in the context of surgical management of epilepsy and brain tumors. Here, Dr. Roozbeh Rezaie will review the utility of MEG as an alternative to traditional invasive diagnostic methods often considered as the “gold standard” techniques for identifying language-specific and determining laterality. Subsequently, we will discuss the application of appropriate MEG language-mapping protocols developed to reliably generate spatiotemporal profiles of language activity. In particular, emphasis will be placed on best-practices for executing validated MEG language-mapping paradigms in adult and pediatric populations, in a variety of scenarios. Furthermore, the practical aspects of analyzing MEG language mapping data will be discussed in detail, using clinical case studies, to illustrate the manner in which brain regions supporting linguistic functions are localized and judgements regarding hemispheric dominance are made. The overall objective of this didactic session will be to familiarize interested practitioners with the advantages (and limitations) of MEG as a functional neuroimaging technique for mapping language and, more importantly, serve as a guide for successfully acquiring and interpreting MEG language mapping data, in a clinical context.

Functional networks impairment along the process of AD: prediction value and resilience factors
Fernando Maestú will discuss a series of studies, which mainly used MEG to record the resting-state activity and a memory task in patients with Mild Cognitive Impairment (MCI), Subjective Cognitive Decline (SCD), and in healthy subjects at preclinical stage or at risk for developing dementia. All these findings together indicate that hyper synchronization of the brain networks could be an excellent non-invasive biomarker for tracking the disease and evaluate interventions.

Brainstorm focusing on MEG
This Masterclass will provide an introduction to Brainstorm, an open-source application committed to the analysis of brain recordings (MEG, EEG, fNIRS, ECoG, depth electrodes and multiunit electrophysiology). Brainstorm’s objective is to share user-friendly tools with those using MEG/EEG as an experimental technique. Brainstorm is an approachable application that has an intuitive interface with no programming knowledge required. Following this introduction Masterclass, we aim to provide a deeper dive into Brainstorm’s capabilities at a later date.
