Today's YNiC Session
by Sam Johnson 29 Jan '09

29 Jan '09

Hello all, Just a quick note to let you know about this afternoon's session. The intention is to very briefly go through the talks that were given at MEG -UK and mention some of the common themes in terms of the problems people are experiencing and potential ways of addressing them. In fact these issues overlap quite heavily with the discussions planned for next week. We don't really want to preempt that discussion, so this afternoon's session will probably be quite short, and to some extent a scene setter for the debate proper on Feb the 5th. That said as ever, all are welcome. Thanks, Sam

International MEG Conference, Athens 2009

---------------------------- Original Message ---------------------------- Subject: International MEG Conference, Athens 2009 From: "Fuller, Susan V" <Susan.V.Fuller(a)uth.tmc.edu> Date: Fri, January 23, 2009 7:02 pm To: "Papanicolaou, Andrew C" <Andrew.C.Papanicolaou(a)uth.tmc.edu> -------------------------------------------------------------------------- Dear Colleagues: I am pleased to announce the 3rd biannual conference of the International Society for the Advancement of Clinical Magnetoencephalography (ISACM) scheduled for September 4th and 5th 2009 in Athens, Greece. The first meeting in Xylokastro, Greece (http://www.uth.tmc.edu/clinicalneuro/mega2005.htm) in 2005 laid the foundations of the Society and resulted in the election of an executive board and the first president, Professor Nakasato, who chaired the second meeting in August of 2007 in the beautiful Matsushima Bay, Japan (http://www.knt.co.jp/ec/2007/isacm/). As it was the case with the two previous meetings, the emphasis of the upcoming one will be on professional issues of great importance to our young Society, to be discussed in a series of plenary round tables, and on new clinical research findings to be presented in the form of posters. You will find the details of the meeting, the associated social events, as well as suggestions for enjoying Greece before and after the conference, on the following website (http://www.uth.tmc.edu/clinicalneuro/ISACM/Welcome.htm). I am looking forward to seeing you in Athens. A.C. Papanicolaou Conference Chairman The University of Texas Medical School 1333 Moursund Street, Suite H 114 Houston, TX 77030 TEL: (713)797-7571 FAX: (713) 797-7590 Andrew.C.Papanicolaou(a)uth.tmc.edu <mailto:Andrew.C.Papanicolaou@uth.tmc.edu> http://www.uth.tmc.edu/clinicalneuro/ <blocked::http://www.uth.tmc.edu/clinicalneuro/>

by Gary Green 20 Jan '09

20 Jan '09

BNA 20th National Meeting - abstract deadline 31st JANUARY! There is only two weeks left to submit an abstract and to register at the early bird fee for the 20th National Meeting of the British Neuroscience Association (19th 22nd April, 2009)! We are delighted to be using for the first time The Adelphi, Liverpool, a unique and historic venue that now offers spacious conference facilities in addition to its other grand rooms and restaurants. And Liverpool is a fascinating city, fast emerging as one of the UKs most stylish, cultured and vibrant conference venues in the UK. So why not come and enjoy some wonderful science in a truly magnificent city and see for yourself whats been going on behind the cranes and the hoardings these past few years. The scientific programme is an exciting and topical array of seven world-class plenary speakers, 20 symposia and over 50 themed poster sessions. For the first time, there are also workshops and a satellite meeting, all FREE to registered delegates. With an equally exciting range of peripheral events and social gatherings (yes, therell even be a Magical Mystery Tour!) this will be a wonderful celebration of neuroscience on UK soil. Registration fees start from as little as £120 (including refreshments and lunches each day too), and the BNA welcomes members and non-members alike. Consult www.bna.org.uk/bna2009/ for further information and all the latest updates. Important deadlines: Early registration (reduced fee): 31st January, 2009 Abstract deadline: 31st January, 2009 Bursary applications: 28th February, 2009 ***************************************************************

19 Jan '09

Dear Users This week's talk on "An Introduction to Minimum Norm Source Analyses" will be given by Pádraig Kitterick from the Department of Psychology. The minimum norm solution will soon be available at YNiC. Pádraig's talk will provide an introduction to minimum norms, including an overview of what the minimum norm is, how the minimum norm works and the advantages and limitations of the minimum norm solution. Everyone is welcome to attend. Best wishes Rebecca -- ************************************************************************ Dr. Rebecca E.

[Fwd: YNiC seminar 15th January] - today
by Gary Green 15 Jan '09

15 Jan '09

Dear Users Today, David Halliday from the Department of Electronics will give a talk. David's talk will be followed by a YNiC project presentation by Philip Quinlan and Nikos Andreadis titled "Switching tasks and anticipating switching tasks: what is the brain doing?". These events will take place at YNiC from 4-5 pm. The title of David's talk is "The Noisy Brain – An introduction to time and frequency domain signal processing techniques for neurophysiological data". http://www.elec.york.ac.uk/staff/dh20.html Abstract: A common feature of neurophysiological signals is the presence of noise, i.e. the signals have the appearance of random processes. In addition, records taken under similar conditions do not have a similar appearance. Analysis of such data therefore requires the use of some form of statistical analysis. For example sample records of EEG recorded from different scalp locations may not look alike, but a statistical analysis may demonstrate that the records share a common underlying rhythm. The field of time-series analysis provides a conceptual and mathematical framework within which random signals, including neurophysiological signals, can be analysed. Two approaches are traditionally used in the analysis of time series – these are the time and frequency domain approaches. The frequency domain approach is generally based on Fourier methods. In the case of two or more simultaneously recorded signals, an important concept is that of correlation, the objective being to assess to what extent the activity in one signal is correlated with that in a second signal. A key frequency domain parameter in this context is the coherence function, which provides a normative linear measure of association between two time series, as a function of frequency. The talk will consider time and frequency domain analyses of neurophysiological signals, including coherence functions. These will be developed within a unified framework where time and frequency domain techniques sit naturally alongside each other, and can be used as complementary forms of analysis. A number of extensions will be discussed, which look at alternative measures of correlation (phase synchronization, causal measures); deal with time dependency (Wavelets, Kalman filtering) and non linearities (higher order spectra). Everyone is welcome to attend. Best wishes Rebecca -- ************************************************************************ Dr. Rebecca E.
