Hello All, Quite a few things this week: 1) IMPORTANT: Our MRI screening safety screening forms have been updated. The updates are explained in our revised local rules. 2) A reminder: Our training documentation (including the local rules referred to above) is held at the following URL https://www.ynic.york.ac.uk/ docs/forms. A login in required to access the URL. 3) Last weeks seminar, which was postponed, will go ahead this week and will follow the project presentation by Shogo Kajimura entitled '*Decoding contents of mind wandering'*. The seminar series details can be found here: https://www.ynic.york.ac.uk/events/thursday-sessions#preview 4) We are currently training 14 operators at YNiC. Best wishes Tony *Tip of the week* You can control the transparency of your overlays in *fslview *by using the blue transparency slider located a the bottom right of the window - see attached -- Antony Morland, PhD.

Update - GE MRI system repair
by Andre Gouws 09 Oct '17

09 Oct '17

HI all, The GE engineer has attended and diagnosed the fault with the system. A replacement part is required for the Oxygen monitor to work correctly. This part is on express order and we hope to have it installed tomorrow, although it is unclear at what point in the day this will be. We are hoping that normal scanning service will resume by Wednesday (11th), but please keep alert for further updates which we will send once we have more information. Thanks, -- André ************************************************************************ André Gouws PhD York Neuroimaging Centre University of York The Biocentre York Science Park Heslington YO10 5NY Tel: +44 (0) 1904 435327 Fax: +44 (0) 1904 435356

GE MRI system fault
by Andre Gouws 08 Oct '17

08 Oct '17

Hi all, I am afraid to report that a sensor fault has developed on the GE system over the weekend. This sensor monitors the safe oxygen level in the MRI environment, and thus the scanner cannot be used until the fault is fixed. GE have said the will attend on Monday AM - we hope to have the scanner up and running as soon as possible. Sorry for those affected by the scanner downtime.

Hello All, We have a Heating and Cooling contractor in attendance today. Alarms may sound. Apologies if they disrupt your work. If an alarm does and stops within 30s there is no need to act. Please be aware that staff may need to ask you to leave at short notice. Thanks Tony -- Antony Morland, PhD.

Weekly update
by Antony Morland 02 Oct '17

02 Oct '17

Hello All, Two things this week 1) The will be a seminar held in the Chemistry Department this week that may interest users: Dr Luisa Ciobanu: Functional MRI at ultra-high magnetic fields Wednesday 4th October 13.00-14.00 In room Chemistry/B101 Abstract Despite the fact that BOLD-fMRI is routinely used to map brain activity and connectivity in preclinical and clinical settings its exact relation with the underlying microscopic changes, either vascular or neuronal, is still not fully elucidated. The development of high magnetic fields promise substantial improvements in the contrast to noise ratio and the spatial resolution with which functional MRI maps are acquired possibly allowing the comparison with other, microscopic, techniques. In the first part of my talk I will review the advantages, but also the challenges, imposed by imaging at ultra-high magnetic fields. Following this, I will present recent results demonstrating that BOLD fMRI faithfully reports microvascular hyperemia, and that the detection of the smallest neuronal activation is limited only by its sensitivity. Beside improved BOLD acquisitions, high magnetic fields allow the development of other alternative ways for studying neuronal activation. In the last part of my presentation, I will describe a novel metabolic imaging approach, based on Chemical Exchange Saturation Transfer (CEST), for assessing the changes induced by neuronal stimulation in rat brains at 17.2T. Specifically, I will present images acquired under glucose-sensitizing conditions showing a significant negative contrast that highlights the same brain regions as those activated in conventional BOLD maps. 2) We are to give 'Tips of the week', hopefully, as the name suggests on a weekly basis. This will largely give advice on IT tricks and work-arounds for commonly occurring analysis tasks. Here's this week's: Scenario: You've submitted a load of jobs to the cluster which you find out will be of no use to you and you want to bring them to a halt. Solution typing: qdel -u <username> into a terminal will stop all cluster jobs submitted by that user, e.g. qdel -u ddc506 Best wishes Tony -- Antony Morland, PhD.

Important information: YNiC schedule for 2017-2018
by Andre Gouws 27 Sep '17

27 Sep '17

Dear All, We have put together a provisional schedule for the YNiC seminars for the academic year. The YNiC led seminars will occur on even weeks during the autumn and spring terms. On the odd weeks we will have seminars on an ad-hoc basis and will largely focus on project presentations or presentations arranged by the YNiC Science Committee. We have also scheduled training opportunities for scanner operators. We would really like new PhD students and postdocs who will want to operate the scanners to take these opportunities as they dovetail nicely into our workload and MSc teaching and training. With that in mind, please note that the first element of training will be held Thursday 28th September. The detailed schedule is attached. Best wishes Tony -- Antony Morland, PhD. Director, York Neuroimaging Centre Department of Psychology, University of York, York YO10 5DD, UK.

This week at YNiC
by Antony Morland 25 Sep '17

25 Sep '17

Hello All, This week we will be having induction sessions for our new intake of PhD and MSc students between 9am and 1pm on Thursday. An introduction to the IT systems will take place between 9am and 1pm on Friday. It will, therefore, be busier than usual in open plan, so please take that into account when planning your work at YNiC. We are hoping to freshen up the posters at YNiC over the next week or so. Could you bring us any spare, but relatively recent, posters that you would like to have on display at YNiC? Many thanks Tony -- Antony Morland, PhD. Director, York Neuroimaging Centre Department of Psychology, University of York, York YO10 5DD, UK.
