Hello
I'm sending out the *YNiC Computing Facilities Survey* again as some
people said they didn't receive it. It would be good to get some more
responses about how you currently use YNiC's computing facilities. So
apologies if you're seeing this again.
https://forms.gle/JN3GnZKXonVmWGWz6
I'd also like to promote the new YNiC wiki we have setup. It's available
here, https://wiki.pages.ynic.york.ac.uk/ and hopefully is a bit easier
to navigate and find things. The old one is mostly out of date and will
be decommissioned soon.
Thanks
Joe

Hello
After an systems upgrade yesterday, we're seeing issues with the Remote
Desktop session handler. As a workaround, we've added a guide to the
wiki on how to login each remote desktop directly
https://wiki.pages.ynic.york.ac.uk/IT/RemoteDesktop/SetUp.html
We're also still having issues with our support email which we hope to
have resolved soon.

Hi All,
The neuroimagoing centre will be closed to researchers between Wednesday
the 20th of December, and Monday the 1st of December, inclusive.
IT work will be taking place on the 20th of December, so access to YNiC IT
systems (including the remote desktops) will be unavailable that day, but
should be available otherwise.
Due to limited staff availability, there will be no operator cover provided
2nd - 5th of January, inclusive, but the centre will be open for
researchers to use the open-plan computing facilities and to run their own
scans.
Please get in touch if you anticipate this causing acute problems.
Cheers,
Rich

Hello,
We're looking for speakers for our YNiC seminar next semester. Everybody is
welcome to present, and presentations can include previously collected
data, new data, pilot data, study plans/ideas, discussions about
theoretical/technical advances or anything else you think others would be
interested in. These usually take place on Wednesdays at 4pm (but we can be
flexible if this time doesn't suit you).
If you don't currently use YNiC, but would like to, this would be a great
opportunity to discuss your area of research and gain inspiration for
future neuroimaging endeavours.
If you are interested, please get in touch!
Many thanks,

To: All Staff and PhD Students <all-psyc-group(a)york.ac.uk>
Hi all,
We are very excited to be hosting an external speaker next Wednesday (29th)
at 4pm in YNiC open plan. Chris Neale from the University of Huddersfield
will be presenting a talk entitled: *Your brain on grass: Environmental
Psychology and the brain*
"Given the increasing levels of urbanisation coupled with our aging
population, there is a need to understand how our urban spaces impact
public health and wellbeing. Environmental psychology has provided numerous
theories and research aiming to understand ways we can optimise our urban
spaces. This has, more recently, extended into neuroscience; specifically
addressing how urban forms impact brain activity in lab, virtual and
real-world settings. This talk will explore some of these findings,
including my own research, and look forward to what the future might hold!"
If you are unable to attend the talk in person, you can catch it on zoom
using the following link:

On Friday October 27th at 12:15 we are launching the “Cogs” discussion
group at YNiC.
Cogs runs alongside existing YNiC events and is intended to help build an
inclusive research culture by welcoming people to the centre and talking
about new and exciting ideas in cognitive neuroscience.
This could include talking about recent papers or new tools, but beyond
that we’re pretty open-minded, so the first meeting will be a chance to
share your thoughts on the format and what we can do to make it work best
for you.
Cogs is open to everyone with an interest in cognitive neuroscience
research, whether that’s undergraduates or masters students running
projects at YNiC, PhD students, postdocs, academic staff and the YNiC team.
This semester Cogs sessions will start at 12.15 on alternate weeks
Semester 1, Week 5, October 27th 12.15 Inaugural welcome and discussion
Further dates this semester - presenters/topics to be announced in due
course (let us know if you want to present, now or in the future)
Semester 1, Week 6, November 10th 12.15
Semester 1, Week 8, November 24th 12.15
Semester 1, Week 10, December 8th 12.15
This timetable will be reviewed at the end of the semester, so let us know
if it works/doesn't work for you and we'll try to take that into account.

Selective retrieval means picking specific memories out of many encoded
traces to
inform present actions. To do so, control processes need to act prior to
the point of retrieval.
Neuroimaging has shown that we can select memories in this way, but little
is known about the
factors and mechanisms that enable pre-retrieval selection in episodic
memory. We tested this in
a first set of electrophysiological studies. Results showed that internal
control modified
recollection-related ERPs – the left parietal old/new effects – when the
external retrieval cues
overlapped with targeted traces. Goal-related effects arising from
comparing ERPs elicited by the
new items also tracked cue overlap before recollection was complete,
indicating that control was
engaged prior to retrieval. But how is selection achieved during retrieval?
Using multivariate
pattern analysis in these two datasets, we showed that study phase neural
patterns matching the
current retrieval goal were reinstated before the retrieval cues were
presented, indicating that
study context was reinstated in preparation to retrieve targeted
information. A final study using
fMRI to investigate selective retrieval in the brain showed that internal
goals alone modified
activation and neural representations of task-relevant features in
content-specific regions. Goal-
directed preparatory reinstatement of study context was detected in both
domain-general control
regions and content-specific regions. However, while activation in domain
general areas
predicted subsequent memory performance, goal-directed reinstatement did
not do so
significantly, suggesting that further, generic control mechanisms may
support readiness to
remember sought-for episodic information.

Dear all,
Beth, myself, and all the YNiC staff are working hard to ensure YNiC is
an open and inclusive environment to conduct amazing cognitive
neuroscience research. Part of that is reviewing a lot of our current
policies and making changes where we think it will help.
One current bottleneck for accessing the MRI scanner is the need for all
"operator-covered", bookable slots to have two YNiC staff acting as
operators. This severely limits the number of hours we can make
available on the booking system. When YNiC provides both operators,
groups do not need to provide an operator but many groups already have
someone who is at least level 0 trained. We are looking to get even
more YNiC researchers trained up to reduce this bottleneck and thus make
more "operator-covered" bookable slots available.
To increase bookable hours, we are moving to a system where YNiC ensures
one YNiC staff as operator. This means, by default, you will be expected
to provide one level 0 trained individual (usually the person running
the study), to ensure we have at least one level 0 and one level 1
individual present at all scans (in line with existing policy). This
will increase the number of operator-covered bookable hours per week
from ~10 - ~16hours. Note, if your lab can provide at least a level 1
and level 0 operator, you are still able to book the MRI scanner outside
of these hours.
We believe this shouldn't affect any projects that are currently
running, but please get in touch if this is not the case. For future
projects, you will be expected to provide a level 0 trained individual
by default. If you cannot do this, then this shouldn't prevent you from
scanning - get in contact with us and we can work something out. The
only real change is we are moving from two YNiC staff by default (with
exceptions when the researcher is level 0 trained) to one YNiC staff by
default (with exceptions when the researcher isn't level 0 trained).
Finally, all supervisors of MSci projects that are about to start
scanning will be emailed directly by a YNiC staff member to ask what
support they need. Please respond to this email as soon as possible so
that we can ensure these projects run as smoothly as possible.
I hope this change, and the rationale for making the change, are clear.
Please get in contact with me and Beth if this is not the case, or you
have specific concerns about how this change might impact your research.
Best wishes,
Aidan

Hi all,
There will be some disruptive building work in the MRI corridor next week
(w/c 2nd Oct). The Siemens scanner will be up and running, data quality
will not be affected, and the Siemens control room will not be affected.
However, the work may be noisy in the MRI corridor at times and
participants will have to walk past construction barriers to access the
SIemens scanner. Please bear this in mind when booking any scans next week.
If you already have slots booked for next week, you can keep them as is, or
let us know if you would prefer and we will remove them free of charge in
this instance.
Thanks

Hello,
Don't forget our new semester of seminars kicks off today at 4pm with two
exciting talks!
We will be hearing from Dr Lauren Welbourne with a short talk titled
"*Measuring
binocular combination of luminance and chromatic stimuli using fMRI"* and
Dr David Watson with a talk titled *"Mapping the connectivity of the scene
network in the human brain"* (see abstract below).
We really hope to see everyone at YNiC! The talks will take place *today
(Thursday the 28th) at 4pm*. If you are unable to attend the talk in

*Dr David Watson*
*Mapping the connectivity of the scene network in the human brain*
The perception of places has been linked to a network of scene-selective
regions in the human brain (OPA: occipital place area; PPA: parahippocampal
place area; RSC: retrosplenial complex). However, the connectivity of these
regions to each other and the rest of the brain remains poorly understood.
Here, we measured the functional and structural connectivity of the scene
network. Functional connectivity, measured at rest and during movie
watching, revealed a bias between posterior and anterior scene regions that
have been implicated in perceptual versus mnemonic aspects of scene
perception. For example, OPA and posterior PPA showed greater connectivity
with visual and dorsal attention networks, which may play a role in the
visual representation of scenes. In contrast, anterior PPA and RSC showed
preferential connectivity with default-mode and frontoparietal control
networks and the hippocampus, which may reflect our memory for places. We
also measured the structural connectivity of the scene network using
diffusion tractography. This indicated both similarities and differences
with the functional connectivity, highlighting distinctions between
posterior and anterior but also ventral and dorsal scene regions. These
findings provide a map of the connectivity of the scene network, informing
possible roles for scene-selective regions in brain function and human
behaviour.

perception. For example, OPA and posterior PPA showed greater connectivity
with visual and dorsal attention networks, which may play a role in the
visual representation of scenes. In contrast, anterior PPA and RSC showed
preferential connectivity with default-mode and frontoparietal control
networks and the hippocampus, which may reflect our memory for places. We
also measured the structural connectivity of the scene network using
diffusion tractography. This indicated both similarities and differences
with the functional connectivity, highlighting distinctions between
posterior and anterior but also ventral and dorsal scene regions. These
findings provide a map of the connectivity of the scene network, informing
possible roles for scene-selective regions in brain function and human
behaviour.
