YNiC Seminar next Wednesday!
by Rebecca Lowndes 19 Oct '23

19 Oct '23

Hi all, Dr Arianna Moccia will be presenting her talk entitled: *How do we select memories? Goal-states and consequences of the pre-retrieval control of episodic memory* We really hope to see everyone at YNiC! The talks will take place *next Wednesday (the 25th of October) at 4pm*. If you are unable to attend the talk in person, 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…> . Quick reminder that all our upcoming seminar talks are on our YNiC seminar calendar: https://calendar.google.com/calendar/u/0?cid=Y19mZDNiNjNhY2Y4NzNiZDVkYzhhZD… We look forward to seeing you then! Becky Selective retrieval means picking specific memories out of many encoded traces to inform present actions. To do so, control processes need to act prior to the point of retrieval. Neuroimaging has shown that we can select memories in this way, but little is known about the factors and mechanisms that enable pre-retrieval selection in episodic memory. We tested this in a first set of electrophysiological studies. Results showed that internal control modified recollection-related ERPs – the left parietal old/new effects – when the external retrieval cues overlapped with targeted traces. Goal-related effects arising from comparing ERPs elicited by the new items also tracked cue overlap before recollection was complete, indicating that control was engaged prior to retrieval. But how is selection achieved during retrieval? Using multivariate pattern analysis in these two datasets, we showed that study phase neural patterns matching the current retrieval goal were reinstated before the retrieval cues were presented, indicating that study context was reinstated in preparation to retrieve targeted information. A final study using fMRI to investigate selective retrieval in the brain showed that internal goals alone modified activation and neural representations of task-relevant features in content-specific regions. Goal- directed preparatory reinstatement of study context was detected in both domain-general control regions and content-specific regions. However, while activation in domain general areas predicted subsequent memory performance, goal-directed reinstatement did not do so significantly, suggesting that further, generic control mechanisms may support readiness to remember sought-for episodic information. -- Rebecca Lowndes Research Technician York Neuroimaging Centre

YNiC - Changes to booking system & operator cover
by Aidan Horner 17 Oct '23

17 Oct '23

Dear all, Beth, myself, and all the YNiC staff are working hard to ensure YNiC is an open and inclusive environment to conduct amazing cognitive neuroscience research. Part of that is reviewing a lot of our current policies and making changes where we think it will help. One current bottleneck for accessing the MRI scanner is the need for all "operator-covered", bookable slots to have two YNiC staff acting as operators. This severely limits the number of hours we can make available on the booking system. When YNiC provides both operators, groups do not need to provide an operator but many groups already have someone who is at least level 0 trained. We are looking to get even more YNiC researchers trained up to reduce this bottleneck and thus make more "operator-covered" bookable slots available. To increase bookable hours, we are moving to a system where YNiC ensures one YNiC staff as operator. This means, by default, you will be expected to provide one level 0 trained individual (usually the person running the study), to ensure we have at least one level 0 and one level 1 individual present at all scans (in line with existing policy). This will increase the number of operator-covered bookable hours per week from ~10 - ~16hours. Note, if your lab can provide at least a level 1 and level 0 operator, you are still able to book the MRI scanner outside of these hours. We believe this shouldn't affect any projects that are currently running, but please get in touch if this is not the case. For future projects, you will be expected to provide a level 0 trained individual by default. If you cannot do this, then this shouldn't prevent you from scanning - get in contact with us and we can work something out. The only real change is we are moving from two YNiC staff by default (with exceptions when the researcher is level 0 trained) to one YNiC staff by default (with exceptions when the researcher isn't level 0 trained). Finally, all supervisors of MSci projects that are about to start scanning will be emailed directly by a YNiC staff member to ask what support they need. Please respond to this email as soon as possible so that we can ensure these projects run as smoothly as possible. I hope this change, and the rationale for making the change, are clear. Please get in contact with me and Beth if this is not the case, or you have specific concerns about how this change might impact your research.

Building work disruption next week
by Rebecca Lowndes 28 Sep '23

28 Sep '23

Hi all, There will be some disruptive building work in the MRI corridor next week (w/c 2nd Oct). The Siemens scanner will be up and running, data quality will not be affected, and the Siemens control room will not be affected. However, the work may be noisy in the MRI corridor at times and participants will have to walk past construction barriers to access the SIemens scanner. Please bear this in mind when booking any scans next week. If you already have slots booked for next week, you can keep them as is, or let us know if you would prefer and we will remove them free of charge in this instance. Thanks Becky -- Rebecca Lowndes Research Technician York Neuroimaging Centre

YNiC seminar 4pm today!
by Rebecca Lowndes 28 Sep '23

28 Sep '23

Hello, Don't forget our new semester of seminars kicks off today at 4pm with two exciting talks! We will be hearing from Dr Lauren Welbourne with a short talk titled "*Measuring binocular combination of luminance and chromatic stimuli using fMRI"* and Dr David Watson with a talk titled *"Mapping the connectivity of the scene network in the human brain"* (see abstract below). We really hope to see everyone at YNiC! The talks will take place *today (Thursday the 28th) at 4pm*. If you are unable to attend the talk in person, 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 look forward to seeing you then!! Many thanks, Becky *Dr David Watson* *Mapping the connectivity of the scene network in the human brain* The perception of places has been linked to a network of scene-selective regions in the human brain (OPA: occipital place area; PPA: parahippocampal place area; RSC: retrosplenial complex). However, the connectivity of these regions to each other and the rest of the brain remains poorly understood. Here, we measured the functional and structural connectivity of the scene network. Functional connectivity, measured at rest and during movie watching, revealed a bias between posterior and anterior scene regions that have been implicated in perceptual versus mnemonic aspects of scene perception. For example, OPA and posterior PPA showed greater connectivity with visual and dorsal attention networks, which may play a role in the visual representation of scenes. In contrast, anterior PPA and RSC showed preferential connectivity with default-mode and frontoparietal control networks and the hippocampus, which may reflect our memory for places. We also measured the structural connectivity of the scene network using diffusion tractography. This indicated both similarities and differences with the functional connectivity, highlighting distinctions between posterior and anterior but also ventral and dorsal scene regions. These findings provide a map of the connectivity of the scene network, informing possible roles for scene-selective regions in brain function and human behaviour. -- Rebecca Lowndes Research Technician York Neuroimaging Centre

Stimuli scripts after YNiC systems upgrade
by Richard Aveyard 21 Sep '23

21 Sep '23

Hi All, I am writing to remind everyone that, following our recent operating system upgrade,* it is important to check that your stimuli scripts are running as intended before resuming scanning*. There are testing PCs available in YNiC for this purpose, and in many cases we can help to resolve issues you might have difficulties with. *Psychopy users* Our testing has highlighted that *some psychopy scripts will be susceptible to inaccurate timing* issues with the new psychopy version (2023.2.0). We now strongly recommend that when initialising your visual window you set waitBlanking=False, or that you ensure your script runs at 120 Hz, and the monitor is adjusted accordingly using the Applications>>Settings>>Display menu. In addition, the event.getkeys() function is deprecated, an example update to fix this can be found here: https://wiki.pages.ynic.york.ac.uk/IT/summer_2023_upgrade.html#psychopy Please remember that it is your responsibility to thoroughly test your stimuli scripts and ensure that everything is working as intended. Cheers, Rich -- Dr Richard Aveyard Senior Technical Specialist York NeuroImaging Centre University of York, UK
