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

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.

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.

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

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.'
