YNiC power off
by Mark Hymers 22 Jul '09

22 Jul '09

Dear all, As you may know, due to complications with the availability of parts, the planned power-down at the Biocentre last month did not occur. Due to this, on Wednesday 29th July at 6pm, the power to the Biocentre will be temporarily cut off. We will therefore have to shut down all YNiC services including the desktops, cluster, servers, web servers and so on. YNiC will therefore close at 1700 to allow staff time to shut all services down in a clean manner. We also suggest that people refrain from submitting jobs to the cluster on Wednesday afternoon as any which are on the cluster when we have to shutdown will be cancelled. We anticipate that power will return at about 9pm. A seperate notice will be sent out by Paul regarding the psychology mail server. Thanks, Mark -- Mark Hymers York Neuroimaging Centre

Dear all, Just to let you know that there will be groups of 6th form visitors on tours of YNiC today, between 2pm and 4pm. During this time, Open Plan in particular will be especially busy. However, computer availability will not be affected. These tours are part of the university Open Day.

Cancellation of electrical work
by Mark Hymers 02 Jul '09

02 Jul '09

Dear all, The electrical work at the Biocentre has been cancelled due to the relevant part not arriving in time. This means that neither psycmail.york.ac.uk or the YNiC systems will be down this evening but that there will be an outage in the future (the timing is yet to be decided and will be sent around as soon as possible). Sorry about the late change, Mark -- Mark Hymers York Neuroimaging Centre

Building work at YNiC
by am501＠psych.york.ac.uk 23 Jun '09

23 Jun '09

Hello All, Some minor building work will be undertaken at YniC from tomorrow onwards. We are having the work done to configure the centre appropriately for the IT upgrades in August. We have been assured that it will not be disruptive, but it is possible that some unforeseen disturbance may occur. I am sorry if you are affected by the work, which should be completed over the next two weeks. Tony

YNiC closure 21/8/09 - 7/9/09
by am501＠psych.york.ac.uk 22 Jun '09

22 Jun '09

Dear all, As you may be aware, YNiC will be undergoing an extensive updating of its computing facilities over the summer. This large-scale project will require a full closure of the centre for two weeks. In order to allow the MSc students to complete their work, we have scheduled the work to commence immediately after the MSc project deadline (21st August). YNiC will therefore be completely closed to users from 17:00 on Friday 21st August until 09:00 on Monday 7th September. We hope you understand that this time will allow us to perform the necessary work to update and imporove the facilities at YNiC. [***** Please note that this will not directly affect the Psychology mail server (although a short outage period of a couple of hours may be necessary over one of the weekends - this will be arranged and announced nearer the time). *****] Many Thanks, Tony

YNiC seminar 25th June
by rem 22 Jun '09

22 Jun '09

Dear Users This Thursday (4-5 pm) in YNiC open plan, there will be a presentation on a "work in progress" MEG project. This project is being carried out by Rebecca Millman and Philip Quinlan. The title of the talk is "The temporal envelope of speech is represented on multiple time scales". Everyone is welcome to attend. Best wishes Rebecca Abstract: "The aim of this study was to determine the auditory cortical mechanisms that form the basis of representing the temporal envelope of speech in humans. The Asymmetric Sampling in Time (AST) model [e.g., Poeppel, D. (2003). The analysis of speech in different temporal integration windows: cerebral lateralization as “asymmetric sampling in time”, Speech Commun. 41: 245-255] proposes that speech perception involves multiple representations of the speech signal on at least two time scales. The AST model posits that the representation of speech is asymmetrical in the time domain as the left auditory areas preferentially integrate information from short (~20-40 ms) temporal windows whilst the right hemisphere homologues preferentially extract information from long (~150-250/300 ms) integration windows. Poeppel and colleagues, (e.g., Poeppel, 2003), suggest that temporal integration is reflected as oscillatory neuronal activity in at least two different frequency bands (theta, gamma). The AST model (e.g., Poeppel, 2003) hypothesises that the hemispheric lateralisation of speech processing results from speech driving gamma activity in the left hemisphere and theta activity in the right hemisphere. Magnetoencephalography (MEG) was used to determine whether changes in power in the canonical electrophysiological frequency bands (delta, theta, alpha, beta, gamma and high gamma) are used to represent speech processing. The speech stimuli were noise-vocoded single words. The attentional state (non-attend vs. attend) of the participants was manipulated. MEG beamformers were used to filter the data into the canonical frequency bands and localise the brain areas involved in processing the speech stimuli on the basis of these frequency bands. The results suggest that 1) the speech temporal envelope is represented on multiple time scales, 2) these time scales are commensurate with the canonical frequency bands corresponding to delta, theta and gamma activity, and 3) the attentional state of the participant modulates the spatiotemporal representation of the speech temporal envelope." -- ************************************************************************ Dr. Rebecca E.
