Learning and limits on adult plasticity for speech Dr Jason Zevin Sackler Institute for Psychobiology Weill Medical College of Cornell University New York, USA 4.30pm, Monday November 9 2009 Psychology A202 (Venables) One way to understand changes in plasticity over the course of development (e.g. sensitive period phenomena) is as a result of the process of learning itself. This is readily observed even in simple neural network models. Learning to categorize speech sounds in one's native language can be characterized as a process of tuning the perceptual system to the dimensions along which change is meaningful in that language. One consequence of this process is a diminished sensitivity to foreign language (L2) contrasts that differ along dimensions not contrastive in one's native phonetic inventory, which ultimately can result in failures to learn even after many years of exposure. This specialization is also reflected in the responses of a network of left-lateralized temporal and frontal cortical regions which respond differentially to native speech contrasts relative to unfamiliar L2 sounds and control stimuli not perceived as crossing a categorical boundary. I will present a series of studies combining behavioral, electroencephalographic and fMRI techniques to examine the traces of early experience on the adult speech perception system.

Greetings all, Tomorrow evening there will be a presentation by me on some of the clinical work we've been performing at the centre, an overview of upcoming clinical research projects and also a brief look at some MEG group analysis which i've recently done. It's in the early stages, but quite interesting. Hope to see you there, i'm sure we can find the stash of refreshments too. Thanks, Garreth

Open Plan Busyness
by Sam Johnson 28 Oct '09

28 Oct '09

Hello all, Just a quick note to let people know that this Thursday afternoon (and in fact the next 6 or 7 Thursday afternoons) will be very busy in open plan with the MSc practical sessions. Due to the numbers it's unlikely you'll be able to get on the machines from about 13:00 till 15:30, as we expect almost, if not all the computers to be in use. More info to follow on the Thursday evening seminar. Thanks, Sam -- Sam Johnson Science Manager, York NeuroImaging Centre University of York http://www.ynic.york.ac.uk

Important updates at YNiC
by Antony Morland 23 Oct '09

23 Oct '09

Dear All, As many of you may know, YNiC has introduced a new charging policy as of October this year. The new charging policy can be found at https://www.ynic.york.ac.uk/information/application. YNiC will now be charging investigators for the use of the facilities at YNiC in line with the policy. We have also updated the Project Proposal Form so it includes details of provisional financial arrangements for planned investigations at YNiC. It can also be found at https://www.ynic.york.ac.uk/information/application. Please note that many of you will be eligible for low charging rates because of your past efforts to raise funds for scanning or because you are a research student. Best wishes Tony

YNiC seminar TODAY
by rem 15 Oct '09

15 Oct '09

Today 4-5 pm in YNiC open plan. Jing Kan from the Department of Computer Science will talk about "Basis functions source model applied to MEG Spatio-Temporal Source Reconstruction". Everyone is welcome to attend. Best wishes Rebecca Abstract: The aim of this paper is to explore a new method of MEG source spatio-temporal reconstruction based on modeling the neural source with extended spherical basis functions. The high resolution 3D cortical mesh is extracted along with the corresponding MRI scan. Inspired by the theory that Laplacian eigenvectors of spherical mesh are equivalent to its basis functions which represent the whole mesh, we build a new model that describes the source distributed on each mesh vertex. This model consists of analogous basis functions and unknown weighted coefficients. Along with the leadfield, the weighted coefficients can be calculated in the light of forward formula of MEG.. The distributed neural source on the mesh is then reconstructed according to the above Basis functions expanded model. Expanding this process from single time point to continuous time series, it is possible to obtain the spatio-temporal reconstructed neural source distributed on cortical mesh vertices. Finally, the method is implemented using real data for signal reconstruction experiments. The robustness of this MEG reconstruction solution is discussed by two aspects. One is to compare with classical methods, i.e. minimum-norm method. The other is to apply the algorithm into meshes with different resolutions. It is clear that these approaches provide a new angle and inspiration of computer graphics to MEG signal reconstruction. Key word: MEG,, inverse problem, eigen-decomposition, basis function, Laplacian eigenvector, spheroidal model, weighted coefficient, spatio-temporal source reconstruction
