Dear Users
Today (4.30-5.30 pm YNiC open plan) Andy Ellis will give a talk on
"Semantically-driven re-activation of visual cortex in object
recognition?".
Summary:
Magnetoencephalography was used to probe the nature and time course of
responses to early and late acquired objects in a covert naming task.
Analysis focused on regions in left occipital and anterior temporal
cortex that have been reported to show stronger responses to early than
late
acquired objects in fMRI. An evoked response in visual cortex around 170
ms was followed by an evoked response in anterior temporal cortex
(150-250 ms) that was stronger to early than late acquired objects. This
was followed by an induced re-activation of visual cortex from 250 ms
onwards that was also modulated by age of acquisition. The talk will
illustrate one way of making statistical comparisons across experimental
conditions in MEG.
Everyone is welcome to attend.
Best wishes
Rebecca

Dear Users
Please be aware that, as of this week, YNiC Thursday seminars will start
at the later time of *4.30 pm*.
This shift in the starting time is necessary to avoid a clash with
teaching sessions in Psychology.
Thank you

Dear Users
Today (4-5 pm YNiC open plan) Chris Racey will give a project proposal
talk on "Processing of real world objects in object selective cortex:
effects of parametric manipulation of size change".
Summary:
The visual system is able to perform recognition tasks in a manner that
appears to be invariant to changes in size of the retinal image. It is
thought that this size invariance is established early on in visual
processing (Goodale & Milner, 1992; Rolls, 2000). The aim of the present
study is to measure adaptation to objects of changing size across the
whole visual system and across several size change conditions which vary
parametrically. The design of the present experiment will be an
fMR-adaptation paradigm similar to that used in our previous work
looking at viewpoint invariance (Racey et al., 2010). We aim to measure
differences in size invariance for objects between the various category
selective brain regions at the level of the Ventral Occipito-Temporal
cortex (VOT). Further, we aim to measure the change in size invariance
moving posterior to anterior through the visual processing hierarchy.
Everyone is welcome to attend.

The security access code for YNiC has been changed today. So if any user
has a set of access door keys for YNiC, and hasn't already been advised
of the new access code, then could they please contact myself or another
member of YNiC staff.
This change has no impact on the door fobs which should continue to work
as before.
Many thanks,
Jo.

Dear Colleagues
As you know, Alliance Medical have now left YNiC.
This means that they obviously are not providing MRI Operators.
The only authorised MRI operators are
Andre Gouws
Mark Hymers
Ross Devlin (temporary appointment to cover clinical projects, but is
available for research scanning from the 5th of January)
others are in training. I will inform you when more operators become
available
Please do not try and operate the magnet console if you are not on the
list. This is for your safety and those of your participants. You will
not be covered by insurance if an incident were to occur.
The full list of operators can always be found at
https://www.ynic.york.ac.uk/information/mri-operators

Hi,
As you are probably aware, YNiC open plan will be closed tomorrow for
staff training. We're also going to take the opportunity to perform a
needed hardware fix on one of the main servers, so it won't be possible
for people to leave analyses running on the machines in open plan or the
cluster. This outage will be from around 9am for an hour or so.
This will also affect the remote desktop service, which will be rebooted
as part of the work - anybody who has suspended sessions should make
sure that they save their work before tomorrow morning. I've explicitly
Bcc'd those who appear to have sessions running to ensure that they know
about this - apologies to anyone who gets the mail twice.
Thanks,
Mark
