Dear Users This Thursday (4.30-5.30 pm in YNiC) Matt Brookes from the University of Nottingham will give a talk on "Imaging brain networks using 7T fMRI and MEG". Please see below for talk abstract. Everyone is welcome to attend and refreshments will be available after the talk. Best wishes Rebecca Abstract: In this talk I will present a summary of our recent work applying 7T fMRI and MEG to the study of functional connectivity. I will begin with a summary of functional connectivity MRI including an overview of the most commonly observed networks. I will then move on to highlight the benefits of 7T over lower field strengths for network characterisation. Following this I will introduce magnetoencephalography (MEG) as a means to measure functional connectivity; I will review several approaches including coherence, imaginary coherence and envelope correlation for connectivity measurement. In particular, problems with such approaches caused by source space signal ‘leakage’ between voxels will be described along with several techniques that may be employed to overcome them. I will expand the seed based approaches to encompass an independent component analysis framework and how it may be used to elucidate both resting state and task positive networks similar to those observed using fMRI. -- ************************************************************************ Dr. Rebecca E.

Dear Users Today (4.30-5.30pm in YNiC) Yury Shtyrov from the CBU will be giving a talk on "Studying language in and by the brain: Configuration and formation of word representations assessed neurophysiologically". Please see below for the talk abstract. Here is a link to Yury's CBU webpage: http://www.mrc-cbu.cam.ac.uk/people/yury.shtyrov/ Yury will be staying for dinner in York. If you would like to join us for dinner please let me know. Everyone is welcome to attend and there will be drinks available after the seminar. Best wishes Rebecca Abstract: Can neurophysiology address questions debated in (psycho)linguistics such as the nature of word representations, how they are formed in learning, what configuration they take and how they interact? In this talk, we will explore the neural reflections of linguistic processing that can be registered using time-resolved neurophysiological recordings available in magneto- and electro-encephalography (MEG, EEG). I will try to convince you of the ultra-rapid speed and automaticity of lexical activations in the brain and the distributed character of word representations dependent on their semantic features. Time permitting, we will see how MEG/EEG can be used to resolve morphosyntactic questions and track the neural correlates of rapid word learning with simple yet precise methodologies that can potentially be used also in clinical assessment of disturbances in linguistic processes -- ************************************************************************ Dr. Rebecca E.

Fwd: Francis Crick Memorial Conference

by Antony Morland

This may be of interest. Apologies if you receive this more than once! Tony -------- Original Message -------- Subject: Francis Crick Memorial Conference Date: Tue, 17 Apr 2012 17:16:48 -0700 From: <secretariat(a)fcmconference.org> To: a.morland(a)psych.york.ac.uk Dear Dr. Morland, Currently we are organizing The Francis Crick Memorial Conference on Consciousness in Human and Non-Human Animals, which will take place at the University of Cambridge. Fifteen leading scientists, including Christof Koch and Stephen Hawking, will be delivering lectures. We are sure that members of the York Imaging Centre will be very interested in attending and so we invite you to advertise our Conference at your Centre, either through the web page's newsletter or through e-mail lists. Details about the Conference are included below. Please feel free to contact me if you have any questions. Sincerely, Daniel Furman Co-Organizer, Francis Crick Memorial Conference Scientific Liaison, NeuroVigil Inc. +1.858.454.5134 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1st Annual Francis Crick Memorial Conference <http://fcmconference.org/> 7th of July - University of Cambridge, UK The Francis Crick Memorial Conference <http://fcmconference.org/>, focusing on "Consciousness in Humans and Non-Human Animals", aims to provide a purely data-driven perspective on the neural correlates of consciousness. The most advanced quantitative techniques for measuring and monitoring consciousness will be presented, with the topics of focus ranging from exploring the properties of neurons deep in the brainstem, to assessing global cerebral function in comatose patients. Model organisms investigated will span the species spectrum from flies to rodents, humans to birds, elephants to dolphins, octopuses to primates, and will be approached from the viewpoint of three branches of biology: anatomy, physiology, and behavior. Until animals have their own storytellers, humans will always have the most glorious part of the story, and with this proverbial concept in mind, the symposium will address the notion that humans do not alone possess the neurological faculties that constitute consciousness as it is presently understood. SPACE IS LIMITED. REGISTER NOW AT http://fcmconference.org/ Contact: secretariat(a)fcmconference.org <mailto:secretariat@fcmconference.org>

YNIC reopens

by Gary Green

Dear Colleagues I am pleased to be able to announce that YNiC is open for scanning. This is possible because of the remarkable efforts of the staff in YNiC over the last 9 weeks and I would like to publicly acknowledge their selfless and tireless efforts. The booking database is available again and scanning is possible in both MRI and MEG. We have checked that data acquired on the scanners can be saved to the main disc arrays within the IT server room and that this data is also archived to tape. Users can now gain access to their home disc spaces and project spaces. We would be grateful if Users could check their files. We do know that a few filenames in a very small number of projects have been changed during the recovery process. The only files that will have been affected are those that originally had a colon character (:) in the filename. This will now be an underscore (_). If you need help or see a change that affects you please send an email to it.manager(a)ynic.york.ac.uk Remote access is now available. Please note that for those who have access to the Remote Desktop service, you need to make sure that you are running version 3.5 of the client (most people will already be doing this) and that a new key is necessary. Instructions on changing the connection key can be found at: https://www.ynic.york.ac.uk/doc/ITPages/RemoteDesktop/InstallingNX To check whether or not you have at least 3.5 installed, please start the NX Client and go to the "About" tab where the version number will be displayed. BUT... We are still waiting for equipment to be delivered to allow a complete resumption of all the services. The key components that are NOT yet available relate to the computing cluster. FSL and Matlab are available and work from the desktop in the open plan area. MEG analysis that uses the computing cluster is not yet available. I will let you know when the compute cluster has been reactivated Gary -- Gary Green Director York Neuroimaging Centre & YNI Ltd The Biocentre York Science Park Innovation Way Heslington York YO10 5NY http://www.ynic.york.ac.uk https://www.ynic.york.ac.uk/about-us/people/ggrg tel. +44 (0) 1904 435349 PA - Jill Hurst : +44 (0) 1904 435329 fax +44 (0) 1904 435356 mobile +44 (0) 788 191 3004
