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

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.

[Fwd: HBM 2009 Call For Abstracts Reminder]

by Gary Green

Apologies if you have already been sent this The Abstract Submission site is open for the 15th Annual Meeting of the Organization for Human Brain Mapping to be held in San Francisco, CA, June 18-22, 2009. Please note that the deadline is *January 11th, 2009 at 11:59 PM CST USA*. Please click here <http://www.llmsi.com/index.php?cid=1425129&forward=2670&curlid=11646> to submit an abstract. Though you are not required to register for the meeting prior to submitting an abstract, the presenter of the abstract must register for the meeting. To take advantage of the lowest registration fee, register online at www.humanbrainmapping.org/sanfrancisco <http://www.llmsi.com/index.php?cid=1425129&forward=2543&curlid=3>_2009_ by March, 15, 2009. Watch for an email announcing the opening of the registration site in January. The Program Committee (PC) of the Organization for Human Brain Mapping's goal is to keep rejection of abstracts low because it wishes to be inclusive. The policy for HBM 2009 will be to reject abstracts that are unethical, incomplete, or contain no data. Statements such as "results will be presented" are not acceptable. The PC also wants the number of posters to be at a level that will provide a positive viewing experience for the attendees. When submitting abstracts for HBM 2009, please consider whether multiple abstracts are truly necessary or if the data you are presenting could be accomplished via submission of one abstract. Thank you for assisting us in increasing the quality of the OHBM Annual Meeting. We look forward to welcoming you to HBM 2009. You can count on the traditional OHBM combination of exciting scientific programs and social events. Do plan to give yourself a little extra time to experience the city of San Francisco. This city by the sea is a bustling metropolis made famous by its most popular landmark, the Golden Gate Bridge. You won't be disappointed. The city has something for everyone. There is an excellent mix of art galleries, attractions, museums, quaint neighborhoods, unique shops, and many ethnic restaurants. For more information, please visit the conference website at www.humanbrainmapping.org/sanfrancisco <http://www.llmsi.com/index.php?cid=1425129&forward=2543&curlid=3>_2009_.

Cortical plasticity: Annual meeting of the British Association for

by awe1＠psych.york.ac.uk

From: AHPD Departmental Contacts [mailto:AHPD-DEPTS@JISCMAIL.AC.UK] On Behalf Of John Draper Sent: 17 December 2008 15:10 To: AHPD-DEPTS(a)JISCMAIL.AC.UK Subject: FW: Call for Symposia: Annual meeting of the British Association for Cognitive Neuroscience Dear colleague, Re: Annual meeting of the British Association for Cognitive Neuroscience (BACN) I would like to invite you to submit proposals for symposia for our 2009 meeting, to be held from 21st - 23rd September at the UCL Institute of Child Health, London. The general theme of this year's meeting is 'cortical plasticity' - a broad theme, but one that is critical for understanding cognition at a number of levels: from sensory learning to language and memory. It also requires convergent methodologies and consequently we encourage you to represent the variety of modern neuroscience methods to address questions such as cognitive development, higher brain function or recovery from injury. We are also open to any alternative suggestions. We are a relatively young society that is keen to support scientists at the beginning of their career. We therefore provide several bursaries for graduate students and a poster prize for exceptional undergraduate projects, the best of whom will be invited to give a platform presentation. There will be opportunity to interact with world-leading neuroscientists from nearby UCL-based neuroscience centres (e.g. the Wellcome Trust Centre for Neuroimaging and the Institute for Cognitive Neuroscience). We also promise a lively social programme - something BACN is well renowned for! Please submit your symposium proposals by the 1st February 2009 directly to me (T.Baldeweg(a)ich.ucl.ac.uk ). Please include a provisional list of speakers and titles. Symposia usually last from 1.5h to 2.5h. Free registration for participants and contributions towards travel expenses are available. I look forward to hearing from you soon. Torsten Baldeweg Chairman BACN PS: For those of you who missed our last meeting in Swansea, a summary is published by ACNR ( <http://www.acnr.co.uk/ND08/ACNRND08_conference.pdf> http://www.acnr.co.uk/ND08/ACNRND08_conference.pdf ). The programme can be found under ( <http://psy.swan.ac.uk/bacn/conference/> http://psy.swan.ac.uk/bacn/conference/).
