Early onset?
by Philip Quinlan 27 Aug '10

27 Aug '10

We recently carried out an MRI study and (to keep it simple) we compared two conditions A and B. We found two regions that preferred A to B, region 1 and 2, respectively. I was keen to explore the time series a little further. So what I did was take the A-B difference for each subject in each of the regions and compute the 95%CI for each 2 sec interval from the start of the stimulus presentation. We get a difference time series for each region and for each point we have a 95%CI. I have plotted the CIs for each point on each function (one for region 1 and one for region 2). Now I note at which time point the CIs reflect a sig diff (i.e., dont cross the x axis) and what I find is that the critical difference occurs earlier for region 1 than 2. At last a window on the time course of psychological functioning? I, of course, now want to claim my Nobel Prize but suspect this is completely flawed. Please advise. Philip. ******************************************************************** Philip Quinlan E-Mail: ptq1(a)york.ac.uk Department of Psychology FAX: (01904) 433181 The University of York Tel: (01904) 430000 Ext. 3135 Heslington Direct : (01904) 433135 York YO10 5DD U.K. ********************************************************************

Today in YNiC
by Gary Green 29 Jul '10

29 Jul '10

There is an additional seminar today At 2pm There will be a talk entitled "NMR and MRI sensitivity enhancement by Parahydrogen Induced Polarization" by Kerstin Münnemann Max Planck Institute for Polymer Research, Mainz, Germany Despite its wide applicability in chemistry, biology and medicine, Nuclear Magnetic Resonance (NMR) spectroscopy still suffers from its inherently low sensitivity. Exploiting the large signal enhancements associated with hyperpolarization techniques, such as Parahydrogen Induced Polarization (PHIP), however, NMR or MRI qualify for monitoring dynamic processes in real time. In this lecture, the synthesis and hyperpolarization of several biocompatible molecules like barbiturates, Vinylpyrrolinidon (blood plasma expander) or Dimethylcarboxylat (precursor to fumarate) will be presented. Polarization transfer to 13C in these molecules by using adequate pulse sequences is demonstrated. Moreover, constant NMR signal enhancement of 1H and 13C is shown using a continuous delivery of parahydrogen by hollow fiber membranes. This allows the acquisition of two-dimensional NMR experiments requiring multiple excitations with constant initial polarization. The membrane technique can be easily extended to produce a continuous flow of a hyperpolarized liquid as will be shown for MRI applications. All welcome

[Fwd: [SPM] Postdoc Position at CBU, Cambridge, UK]
by Gary Green 27 Jul '10

27 Jul '10

FYI ----------- *MRC Cognition and Brain Sciences Unit -- Cambridge* *Neuroimaging Methods Post to Study Ageing* The MRC Cognition and Brain Sciences Unit is an internationally renowned research institute with state-of-the-art cognitive neuroscience facilities, including Siemens 3T MRI and 306-channel Elekta-Neuromag MEG scanners. A 2 year post-doctoral position is available to support the newly-established Cambridge Centre for Ageing and Neuroscience (CamCAN), funded by the UK BBSRC in order to relate changes in the brain with changes in cognitive function across the adult lifespan. You will be part of a Cambridge-wide collaboration, working to develop and maintain the storage and analysis pipelines for large quantities of MRI, fMRI and MEG data. This post will be available from January 2011. You will have a PhD in neuroscience, scientific computing or a related area, plus experience of analysis of neuroimaging data, such as MRI, fMRI and/or MEG. You should have excellent IT skills, being familiar with Linux and Matlab, and ideally with specialised neuroimaging analysis software. Experience of studying changes in the brain with ageing, and of cognitive neuroscience would be an advantage. You will be thorough, efficient, effective, a good communicator, and enjoy working as part of a diverse and energetic team. The starting salary will be in the range of £26,022 - £31,758 depending upon qualifications and experience. We offer a flexible pay and reward policy, 30 days annual leave entitlement, and an optional MRC final salary Pension Scheme. On site car and cycle parking is available.

Matlab versions
by Mark Hymers 27 Jul '10

27 Jul '10

Hi, As I mentioned a while back, just before the start of next term (September 2010) we'll change the default Matlab version to R2010a (7.10). This is just a reminder that it would be helpful if people could quickly check that any extra toolboxes or scripts which they rely on still work under 7.10 and let me know of any problems they see. If we don't get any reports, we'll assume that it's all ok. R2009a (7.8) will still be available until September 2011 as shown at: https://www.ynic.york.ac.uk/doc/ITPages/FAQ/Misc/SupportedVersions#Matlab Thank you, Mark -- Mark Hymers York Neuroimaging Centre
