YNiC seminar 10th February
by rem 07 Feb '11

07 Feb '11

Dear Users This week (4.30-5.30 pm at YNiC), there will be two presenters giving talks for the YNiC seminar: 1) Nora Vyas, King's College London Title TBC http://kcl.academia.edu/NoraVyas 2) Tom Hartley, Department of Psychology YNiC project proposal "Efficient Localisation of the Human Grid System". Summary: "In 2005, a remarkable new class of cells was discovered in the medial entorhinal cortex of the rat, forming an important input to the hippocampus. As an animal moves about its environment, grid cells fire at an array of locations spanning the environment to form an equilateral triangular grid (see http://www.scholarpedia.org/article/Grid_cells for more information). The crystal-like repeating symmetry of the grid cells' multipeaked firing patterns is unique and the grids form a completely novel and hitherto unanticipated type of neural representation. Doeller and colleagues (Nature, Feb 2010) showed that signatures of this grid system could be detected in fMRI data from humans exploring a virtual environment. However this was only possible using a complex retrospective analysis, so it was not possible to manipulate properties of the environment or task to examine the grid system's properties systematically. This project proposes a new method for localising the grid system efficiently, using an experimental design which fully exploits its remarkable and unique regularity. If this method proves viable, it will enable us to quickly localise the grid system in each individual so that its detailed properties and role in behaviour can be fully and thoroughly investigated." Everyone is welcome to attend. Best wishes Rebecca -- ************************************************************************ Dr. Rebecca E.

Emailing personal details
by Antony Morland 07 Feb '11

07 Feb '11

Dear All, In the past we have recommended that participants are registered 24 hours in advance of their first scan. To help with this we have accepted participant details via emails. I am afraid that will no longer be able to do this because we are not permitted send and receive personal details by email. We are still able to take hardcopy forms. We will always attempt to register participants as speedily as possible, but we can only guarantee registration if forms are supplied 24 hours in advance of the scan session. Tony

Scanner Updates
by Sam Johnson 07 Feb '11

07 Feb '11

Hello all, I'm pleased to report that MEG has been stable since Thursday evening. We ran several tests on Friday and the system is working well and the replacement board seems to have solved the problem. Those with active MEG projects should be able to scan with much greater confidence from now on. I'm afraid the news isn't quite so good from MRI, the distortions in the images are still present. Engineers are on site and working on the problem, and we'll let you know as and when progress is made. Thanks, Sam -- Sam Johnson Science Manager, York NeuroImaging Centre University of York http://www.ynic.york.ac.uk

update on MRI and MEG
by Gary Green 03 Feb '11

03 Feb '11

Dear Users I am sorry to say that both MRI and MEG are still unavailable. MRI: We are closer to understanding the problem. It appears to be related to shimming and that there is a fault with a/the shim coil(s). Engineers are on site. MEG: We will get a possible replacement board today and we will know, tomorrow, whether this is a solution to the fault on the REI board.

MRI and MEG problems
by Gary Green 02 Feb '11

02 Feb '11

Dear Users I am sorry to say that we are having some problems with MRI and MEG. MRI is down because the Y gradient system is faulty. The engineers from GE have been working on this since Monday morning. Unfortunately the problem is compounded by a water leak from the new air handling system into the floor space where there are high voltage cables. MEG has also been problematic of late due to an intermittent fault with a key board, the REI card. This handles information flow from the sensors. Although we have, in the past, managed to correct the fault, the problem now, as of this week, seems to be occurring more frequently. We have taken steps to replace the board and we hope to have done so by Friday. Unfortunately the work we are doing to completely replace the electronics will not be finished until later in the year. I will keep you informed of progress with correcting these faults. In the meantime, I apologise for the inconvenience caused, Gary -- Gary Green York Neuroimaging Centre The Biocentre York Science Park Innovation Way Heslington York YO10 5DG http://www.ynic.york.ac.uk https://www.ynic.york.ac.uk/about-us/people/ggrg tel. +44 (0) 1904 435349 PA +44 (0) 1904 435329 or reception(a)ynic.york.ac.uk fax +44 (0) 1904 435356 mobile +44 (0) 788 191 3004

YNiC seminar today
by rem 27 Jan '11

27 Jan '11

Dear Users Today (4.30-5.30 pm YNiC open plan) Ed Silson will give a project proposal presentation on "Functional Properties of LO-1 and LO-2 in human Lateral Occipital cortex" Summary: The Lateral Occipital (LO) cortex is known to be an object-selective brain region. Although originally thought not to contain a retinotopic organisation, recent evidence suggests that LO contains two adjacent representations of the contralateral visual field, referred to as LO-1 and LO-2 (Larson & Heeger, 2006). Larson and Heeger (2006) suggested that LO-1 and LO-2 might have different functional properties and that both contribute to object recognition. We aim to use functionally-guided TMS to probe the functional properties of LO-1 and LO-2. Everyone is welcome to attend.
