Dear Users This Thursday (YNiC open plan from 4.30 pm) there will be a presentation by Krish Singh from CUBRIC. The title of Krish's talk is "Non-invasive MEG measures of cortical oscillatory dynamics in health and disease". Abstract: Magnetoencephalography (MEG) allows the non-invasive localisation and characterisation of a range of cortical oscillatory phenomena, which are increasingly thought to reflect both local and network properties of the neural populations underpinning different aspects of perceptual and cognitive function. These studies reveal complex, task-specific and spatially localised effects, some of which appear to be co-localised with the BOLD-fMRI response to the same task. In this talk I shall explain some of the methodology behind these studies and how these human MEG signals compare with invasive recordings in both animals and humans. The main focus will be in looking at how individual differences in oscillatory parameters such as amplitude and frequency can be related to variations in perceptual/behavioural task performance and to individual differences in neurotransmitter concentrations. Finally I will talk about the relevance of these studies to clinical conditions such as Epilepsy and Schizophrenia. Everyone is welcome to attend and refreshments will be provided afterwards.
