Dear Users This afternoon (4.15-5.15 pm in YNiC) I will be giving a talk on ""Representations of the temporal envelope of sounds in human auditory cortex: Comparing results from non-invasive MEG "virtual electrodes" and invasive intracortical electrode recordings". Magnetoencephalography (MEG) is a non-invasive neuroimaging technique that provides direct measurements of neural activity with a millisecond temporal resolution. An important application of MEG "virtual electrode" analyses is linking non-invasive MEG measurements and invasive electrophysiological recordings in animals (e.g. Zumer et al., 2010) and humans (e.g. Hall et al., 2005; Dalal et al., 2008, 2009). In this talk I will present results from a study that used non-invasive MEG "virtual electrodes" to try to replicate the results from an invasive intracortical electrode study (Nourski et al., 2009) on the mechanisms for encoding the temporal envelope of speech in human auditory cortex. Everyone is welcome to attend and refreshments will be provided after the talk. Best wishes Rebecca -- ************************************************************************ Dr. Rebecca E.

YNiC seminar today
by rem 20 Oct '11

20 Oct '11

Dear Users Today (4-5 pm in YNiC) there will be a project proposal presentation by Mark Hymers. The title of the project is "The functional organisation of the recognition of speech and music". Please see below for the talk abstract. Everyone is welcome to attend and refreshments will be provided after the talk. Best wishes Rebecca ****************************************************************** Mark Hymers and Rebecca Millman Abstract: There is debate in the literature over the extent to which speech and music perception recruits shared computational systems (e.g. Patel, 2003; Peretz and Zatorre, 2005; Fedorenko et al., 2009; Rogalsky et al., 2011). The proposed study will use functional Magnetic Resonance Imaging (fMRI) and “perceptual pop-out” to determine the neural basis of both speech and music recognition. Perceptual pop-out is achieved by presenting a degraded/distorted musical or speech sound that appears meaningless when heard for the first time but is easily recognisable after hearing an undegraded/undistorted version of the same sound. Perceptual pop-put has been used in previous studies of speech recognition (e.g. Liebenthal et al., 2003; Giraud et al., 2004; Möttönen et al., 2006) but not, to our knowledge, in studies of melody recognition. In this study we will take advantage of the effect of perceptual pop-out for both music (known melodies) and speech (IEEE sentences) stimuli to control for acoustical differences in the musical and speech stimuli. This approach will allow us to determine the extent of organisational overlap in the representation of music and speech recognition within the same group of participants. -- ************************************************************************ Dr. Rebecca E.

YNiC business

18 Oct '11

Hello all, It's that time of year again, when the latest horde of master students descend. Thursday afternoons for the rest of this term will be very busy in the open plan area of YNiC. There won't be any free machines, and any machines logged in will be logged out, so from about 1-3:30 you shouldn't plan to be using the desktops in YNiC. Apologies for any inconvenience. Thanks, Sam -- Sam Johnson Science Manager, York NeuroImaging Centre University of York http://www.ynic.york.ac.uk

Fwd: [megcommunity] Senior Lecturer or Associate Professor in Neuroscience (MEG)
by Gary Green 13 Oct '11

13 Oct '11

FYI -------- Original Message -------- The Brain & Psychological Sciences Research Centre (BPsyC) at Swinburne University, Melbourne, Australia, is seeking candidates for a Senior Lecturer or Associate Professor in Neuroscience (MEG). The Centre has recently taken possession of an Elekta Triux MEG scanner, to complement the existing Siemens 3T Trio MRI, TMS and EEG facilities, and is seeking to expand the existing MEG expertise within the team. The position will have the following principal roles: (i) developing, conducting and advancing research with a focus on magnetoencephalography (MEG), particularly its clinical applications; (ii) providing consultation in cognate teaching areas, and (iii) contributing to administration within the centre under the direction on the Centre Director and Executive Committee. Applicants must hold a PhD in a relevant subject along with a strong track record of peer reviewed publications and success in attracting competitive external funding. International applicants will receive relocation support. For further details please see http://tinyurl.com/3jk24kj Closing date for applications is 30th October 2011. For those not familiar with Melbourne, it recently came top in a survey of the world's best cities in which to live. From the Wall Street Journal - 'Straddling the Yarra River, Melbourne boasts a European-style cafe culture of hidden coffee spots and restaurants as well as a passion for sport, including an annual Formula One grand prix, cricket, rugby and homegrown Aussie rules football.' -- Will Woods Brain and Psychological Sciences Research Centre Faculty of Life and Social Sciences Swinburne University of Technology P.O Box 218 Hawthorn, VIC, 3122 Australia Phone:(61 3) 9214 5946 Fax: (61 3) 9214 5525

Interesting new explanation for why fMRI scanners cause dizziness.
by Chris Racey 04 Oct '11

04 Oct '11

This might be important for anyone planning on doing eye tracking in the scanner because the described process causes abnormal eye movements... http://www.sciencedirect.com/science/article/pii/S0960982211009353 Chris

PS. I should add that before you get carried away with the recent 'advice' by Nieuwenhuis et al. (2011, Nature Neuroscience) consult VIckers and Altman (2001)! ******************************************************************** Philip Quinlan E-Mail: ptq1(a)york.ac.uk Department of Psychology FAX: (01904) 323181 The University of York Tel: (01904) 320000 Ext. 3135 Heslington Direct : (01904) 323135 York YO10 5DD U.K. ********************************************************************
