MEG-UKI meeting, registration now open
by Richard Aveyard 31 May '23

31 May '23

Hi all, See below for details of a great opportunity to get (re)acquainted with MEG at the MEG-UKI conference, ahead of the installation of our much-anticipated new OPM system towards the end of the year. Cheers, Rich Dear all, I'm delighted to say that the registration is now open for the MEG-UKI conference taking place in Trinity College Dublin on 27th and 28th October 2023 https://meguk.ac.uk/meg-uki-2023-conference/. As places are limited (200 max), we are starting by inviting the consortium labs to register first. I would be really grateful if you could do so as soon as you can to ensure your places are reserved before we advertise the meeting more widely. As you'll see, there is a really nice lineup of talks there. In the end, we didn't feel it was possible to dedicate separate slots to every lab in the consortium as has been done in previous years and instead opted to group the talks thematically, based on the speaker nominations that you provided while also trying to maintain a good balance in terms of gender diversity. We're accepting poster submissions and will be selecting 4 additional early career speakers based on those abstracts so there are still opportunities there for any labs not currently represented to appear in the lineup. Please do get in touch if you have any feedback on the webpage itself or on the running of the meeting. Please also feel free to share the registration link with other labs at your institution who may be interested in attending. Really hope you can join us for what promises to be a fun couple of days! All the best Redmond ____________________________ Redmond G.

YNiC Seminar This Week
by Jennifer Ashton 31 May '23

31 May '23

Hello, Just a quick reminder that we have a YNiC seminar *tomorrow* (Thursday 1st of June) at 4pm. This will be the last one of the term and will be given by *Dr Daniel Baker, Dr Lauren Welbourne and Dr Joel Martin.* *Title:* Non-canonical binocular pathways in human vision *Summary:* The classical view of binocular combination is that signals from the two eyes remain anatomically segregated until they reach V1, where they are combined. However there are additional locations in the brain where binocular combination might occur independently of V1, and which subserve functions other than conscious visual perception. These include the network of subcortical nuclei responsible for determining pupil diameter, and a potential direct koniocellular projection from LGN to MT that might process rapid motion. We know relatively little about how binocular combination operates in these pathways, so conducted an fMRI study in which five different stimuli were presented either monocularly or binocularly. The stimuli include flickering gratings, a flickering disc (intended to stimulate light-sensitive pathways), and rapidly drifting achromatic and isoluminant stimuli (intended to target motion pathways). We will report the results of whole brain and ROI-based analyses. Refreshments will be provided for those attending the talk at YNiC, or you can catch it on zoom using the following link: https://york-ac-uk.zoom.us/j/96762553290?pwd=UEluT1lMd3V5azY5YzNmWkJCV1VTdz… <https://www.google.com/url?q=https://york-ac-uk.zoom.us/j/96762553290?pwd%3…> We hope to see you there! :) Many thanks, Jennifer -- Jennifer Ashton, PhD Senior Research Technician York Neuroimaging Centre Working days: Monday, Tuesday and Wednesday

Reminder: YNiC seminar today!
by Rebecca Lowndes 25 May '23

25 May '23

Today's seminar at 4pm in person or on zoom. Refreshments will be provided. https://york-ac-uk.zoom .us/j/96762553290?pwd=UEluT1lMd3V5azY5YzNmWkJCV1VTdz09 <https://www.google.com/url?q=https://york-ac-uk.zoom.us/j/96762553290?pwd%3…> The role of localised sleep spindles in adaptive memory consolidation Summary: Sleep spindles are 12-15Hz waxing and waning neural oscillations occurring during non-rapid eye movement sleep. They are believed to be mechanistically involved in memory consolidation, the strengthening and stabilisation of recently acquired memories, through inducing LTP and synaptic plasticity in learning-related hippocampal-cortical networks. A recent framework proposes that spindle-mediated memory consolidation should favour so-called adaptive memories, those experiences that are personally salient or goal-relevant. In this talk, I will present an outline for a study designed to directly test this hypothesis for the first time. I will employ a lateralised encoding task and present stimuli to a single visual field that should create distinct encoding representations in the contralateral hemisphere. Memory for items in one visual field will be prioritised for consolidation by being associated with a financial reward if remembered at a post-sleep test. I hypothesise that during sleep, sleep spindle activity will be heightened over the rewarded hemisphere (compared with unrewarded), and that this spindle activity will correlate with memory for the high-reward items. See you all there Becky -- Rebecca Lowndes Research Technician York Neuroimaging Centre

YNiC Seminar - TOMORROW
by Rebecca Lowndes 10 May '23

10 May '23

Hi all, Don't forget we have a YNiC seminar by *Dr Tirso Gonzalez Alam *titled "*Visual to default network pathways: A double dissociation between semantic and spatial cognition**" *tomorrow (Thursday) at 4pm. The seminar will be in person at YNiC. You can also use the following link to catch the seminar on zoom https://york-ac-uk.zoom .us/j/96762553290?pwd=UEluT1lMd3V5azY5YzNmWkJCV1VTdz09 <https://www.google.com/url?q=https://york-ac-uk.zoom.us/j/96762553290?pwd%3…> See you there! Becky *Visual to default network pathways: A double dissociation between semantic and spatial cognition* Tirso Gonzalez-Alam, Katya-Krieger-Redwood, Dominika Varga, Zhiyao Gao, Aidan Horner, Tom Hartley, Magdalena Sliwinska, David Pitcher, Jonathan Smallwood, Elizabeth Jefferies *Abstract* The Default Mode Network (DMN) often deactivates to visual input yet it can couple to visual cortex, and it is composed of multiple subsystems that might differ in their degree of visual coupling or in the memory representations that they support. We used a combination of univariate, connectivity and multivariate fMRI analyses across three samples (combined N > 250) to investigate the architecture connecting visual cortex to DMN, and the engagement of visual-DMN pathways in memory-guided decisions across two domains (semantic and spatial). Participants learned virtual environments consisting of buildings populated with objects, with half of the buildings containing objects from a single semantic category allowing them to associate space with meaning. In a second session, they made spatial and semantic decisions about these buildings and objects in the scanner. We found semantic and spatial judgements engaged distinct DMN subsystems. Frontotemporal DMN regions were primarily engaged by semantic judgements and showed stronger connectivity to object perception regions in lateral ventral occipital cortex, while medial temporal DMN regions were more strongly recruited during spatial judgements and showed stronger connectivity to medial visual regions involved in processing scenes. Clusters in angular gyrus and ventral lateral occipital cortex, topographically situated between these pathways, were implicated in the integration of semantic and spatial information, suggesting a mechanism for the interaction of these distinct visual-to-DMN pathways. These results show how processing streams that capture different unimodal to heteromodal transformations relevant to conceptual and spatial processing might interact at multiple levels of the cortical hierarchy to produce coherent cognition. -- Rebecca Lowndes Research Technician York Neuroimaging Centre

Siemens MRI down for repair
by Andre Gouws 09 May '23

09 May '23

Hi all, We encountered and error with the Siemens MRI scanner today. The engineers are being booked in to resolver the issue and we hope it will be a relatively quick fix. We will keep you posted, but as it stand the system is down as it requires some parts. More news will follow as soon as we have any, -- André ************************************************************************ André Gouws PhD Lead Technical Specialist York Neuroimaging Centre and York Diagnostic Imaging Departmental Safety Advisor - Dept. of Psychology University of York The Biocentre York Science Park Heslington YO10 5NY
