Dear all,
On Thursday evening at 6pm, the power to the Biocentre will be
temporarily cut off. Due to this, we'll 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 Thursday 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 about the psychology mail server.
Sorry about the short notice,
Mark

This week Tim Andrews will give a talk on "The representation of facial
identity in visual cortex" from 4-5 pm in YNiC open plan.
Everyone is welcome to attend.

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
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
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."

Dear Users
There will not be a YNiC seminar this Thursday (11th June) as it is the
undergraduate Leaving Day.

Dear Users
This afternoon the Vice-Chancellor will be visiting YNiC. He will be
showing the Chief Executive of HEFCE around the scanners and open plan area.
They will arrive at about 3pm and leave at 3.45.
If you are going to be working in YNiC today it would help us a lot if
you could endeavour to be in YNiC during that time. We will ask people
in the open plan to be prepared to say something about their work as I
am sure the VC will select someone as he has done so on other visits.
In MEG Andre will be demonstrating responses to visual stimuli and Mark
Hymers, Michael Cowley and Simon Duckett will be demonstrating
hyperpolarisation in MRI
thanks
