Hi everyone Here's what's going on this week at YNiC: *Project Presentation - Thursday 4pm:* This week we have a project presentation from Dr Daniel Kaiser and Matt Foxwell on Thursday 21st November at 4pm in YNiC open plan, titled: "Probing effects of scene structure on object perception using TMS". Talks are followed by refreshments. We hope to see you there! *Strike Action:* As you may be aware, UCU have announced an 8 day period of strike action commencing 25th November. As yet we are not aware of any impacts on activities at YNiC. Should any impact arise, we will make all efforts to keep you informed. *Cluster Output Paths:* >From Monday 25th November you will only be able to write data to /scratch/groups, and not straight to /groups. This is already the recommended best practice at YNiC, but we will be enforcing it from next week to reduce storage pressure on the /groups drive. Please make sure you edit any of your scripts that currently save straight to /groups. *YNiC User Inductions:* If you are aware of any new students/staff that will require access to YNiC and/or an IT account, they must attend a YNiC user induction. Our next induction date will be Wednesday 27th November at 2pm. Please ask them to contact support(a)ynic.york.ac.uk to sign up. Hope you have a good week! Kind regards Lauren -- Lauren Welbourne, PhD Senior Research Technician lauren.welbourne(a)york.ac.uk York Neuroimaging Centre University of York Innovation Way Heslington York YO10 5NY

Reminder: Guest Speaker Dr Melanie Burke @ YNiC 4pm TODAY
by Lauren Welbourne 14 Nov '19

14 Nov '19

Hi everyone This afternoon we have a guest speaker at YNiC - Dr Melanie Burke from the University of Leeds. She will be presenting at *4pm in YNiC open plan*. Refreshments will be provided after the talk. Please find the title and abstract below: *Title:* “Inducing neuroplasticity in the prefrontal cortex: a preliminary investigation into the effects on the brain and cognition.” *Abstract:* Theta burst stimulation (TBS) is a form of repetitive transcranial magnetic stimulation (rTMS) that can be used to increase (intermittent TBS) or reduce (continuous TBS) cortical excitability. The current study used iTBS in 18 adults, to investigate the causal role of the dorsolateral prefrontal cortex (DLPFC) during the performance of four cognitive functions: attention, inhibition, sequence learning and working memory. Participants performed the cognitive tasks both before and after iTBS stimulation and functional near infra-red spectroscopy (fNIRS) was monitored throughout. Preliminary findings of brain activity before, during and after TBS, alongside eye movements responses to the cognitive tasks will be presented. We hope to see many of you there!

It relies on a tradeoff between exploration and exploitation attentional policies to select and maintain attentional focus on the relevant streams of information while remaining alert to unexpected changes. Several studies have identified some neural correlates supporting such attentional dynamics. For instance, top-down and bottom-up types of attention are respectively delineated by the dorsal and ventral neural networks that are in close interaction with the anterior cingulate cortex for resource allocations. Efficient divided attention results in an enhancement of task relevant networks activity via cross frequency coupling in the theta and gamma band and enhancement of secondary task networks activity at different phase to that of primary task networks. However, when task demand exceeds mental capacity, the homeostasis between the ventral and dorsal pathways is disrupted, leading to the suppression of non-primary task relevant network (via increased alpha oscillations) and decreased frequency coupling between theta and gamma in primary task networks. Although this shielding mechanism can prevent from mental overload and distractions, missing critical information can have devastating consequences in real-life scenarios such as driving or operating an aircraft (eg. auditory alarms). The candidate is expected to design and conduct experiments to investigate the shift from efficient to non-efficient divided attention between the visual and the auditory modality. These experiments will be conducted 1) in the lab using fMRI and high-density 2) under highly ecological conditions with portable EEG. The candidate is expected to perform state-of-the-art analyses including effective connectivity and to apply inverse reinforcement learning (IRL) technics to 1) estimate the efficient (optimal) and non-efficient (sub-optimal) policies with respect to best expected distribution of attention. 2) to predict long-term attentional efficiency. The ideal candidate will have a strong background in Neurosciences, brain imaging (EEG or/and fMRI/MEG), signal processing, artificial intelligence for automated learning and planning. She/he will have to work in strong collaboration with the three other researchers (2 PhD students, 1 post doc) funded by the ANITI program. This research will be conducted within the stimulating environment of Neuroergonomics lab at ISAE-SUPAERO (25 researchers), the Artificial and Natural Intelligence Toulouse Institute. The candidate will have the opportunity to have a long stay in Cinet (Osaka/Japan) at Daniel Callan’s research department to conduct the fMRI or MEG experiment. *References* • Durantin, G., Dehais, F., Gonthier, N., Terzibas, C., & Callan, D.

This Week at YNiC
by Lauren Welbourne 04 Nov '19

04 Nov '19

Hi everyone Here's what's going on this week: *YNiC Monthly Science Social:* We're kicking off the first Science Social session with a talk by Andre on DTI scanning; this should be a really interesting introduction to this type of scan, plus we'll be providing pizza, so we hope to see many of you there! The session will be held in YNiC open plan this *Thursday 7th Nov at 4pm*. For a list of the upcoming Thursday sessions, please visit https://www.ynic.york.ac.uk/events/thursday-sessions. *Level 0 operator training:* The upcoming Level 0 training session this week is now fully booked. Our next scheduled training session will take place on *Wednesday 11th December at 2pm-4pm*. Please note that users requesting Level 0 training should be a PhD, RA/Postdoc, or staff, and should already have a project proposal submitted to YNiC. Please email support(a)ynic.york.ac.uk if you have any questions or wish to book on to this session, and include which scanner you wish to be trained on. *Please note that sessions are limited to 4 trainees, which will be allocated on a first-come first-served basis. Training must be booked at least a week before the session date, in order to reserve the scanner booking.* *It is recommended that all Level 0 operators attend an 'Emergency First Aid at Work' one-day training course.* This is currently a requirement for Level 1 operators, and will also be required for Level 0 operators soon - we will enforce this requirement from March 2020, to give current Level 0 users time to arrange the training course. Courses should be organised by the project PI with a relevant training provider (e.g. St Johns Ambulance, Red Cross); these providers can also run group training sessions (8 or more people) on-site, so labs may wish to coordinate their operators to all attend training on the same day, at a location of your choice. *YNiC User Inductions:* If you are aware of any new students/staff that will require access to YNiC and/or an IT account, they must attend a YNiC user induction. Our next induction date will be Wednesday 13th November at 2pm. Please ask them to contact support(a)ynic.york.ac.uk to sign up. *Christmas Closure:* We'd like to give you advance warning that YNiC will be closed to users from the week commencing 16th December, and will re-open in the New Year, on the 3rd of January. Hope you have a great week.

Hi everyone We have quite a few notices for you today, including a chance to *win a bottle of wine* if you read until the end! *Level 0 training:* We have reviewed the Level 0 training process, and now, in addition to the training session, Level 0 trainees will also be observed for a minimum of 3 scan sessions, until we are satisfied that they meet operator requirements (these scans must be booked in operator-covered slots). We therefore recommend that you only book onto a training session when you have ethical approval for a project, and intend on scanning within the next couple of months. Our next scheduled *Level 0 training session *is at *2pm on 6th November*, please email support(a)ynic.york.ac.uk to book on to this session, and include which scanner you wish to be trained on. Training will take up to two hours. *Please note that sessions are limited to 4 trainees, which will be allocated on a first-come first-served basis. Training must be booked at least a week before the session date, in order to reserve the scanner booking.* *First Aid Training for Level 0 operators:* It is recommended that all Level 0 operators attend an 'Emergency First Aid at Work' one-day training course. This is currently a requirement for Level 1 operators, and will also be required for Level 0 operators soon - we will enforce this requirement from March 2020, to give current Level 0 users time to arrange the training course. Courses should be organised by the project PI with a relevant training provider (e.g. St Johns Ambulance, Red Cross); these providers can also run group training sessions (8 or more people) on-site, so labs may wish to coordinate their operators to all attend training on the same day, at a location of your choice. *User Inductions:* If you are aware of any new students/staff that will require access to YNiC and/or an IT account, they must attend a YNiC user induction. Our next induction date will be Wednesday 30th October at 2pm. Please ask them to contact support(a)ynic.york.ac.uk to sign up. *Monthly Science Social Seminars:* On the first Thursday of every month YNiC will be hosting a 'Science Social' at 4pm in YNiC open plan. This will include a talk or discussion on topics that will include imaging methods, software, and analysis techniques. We also encourage users to volunteer to present if they would like to share something that they think may be of interest to other users. Pizza and drinks will be provided! *Halloween 'Scary Slice' Game:* This week at YNiC you will have a chance to win a bottle of wine by correctly matching the staff member to the MRI slice (a coronal slice of the face that is suitably scary and Halloween-y). Images will be up on the white board in open plan until the end of the day on Thursday. The person that correctly matches the most images will be awarded the bottle of wine - good luck! Hope you have a great week!
