Hi all,
See below for details of a great opportunity to get (re)acquainted with MEG
at the MEG-UKI conference, ahead of the installation of our
much-anticipated new OPM system towards the end of the year.
Cheers,
Rich
Dear all,
I'm delighted to say that the registration is now open for the MEG-UKI
conference taking place in Trinity College Dublin on 27th and 28th October
2023 https://meguk.ac.uk/meg-uki-2023-conference/. As places are limited
(200 max), we are starting by inviting the consortium labs to register
first. I would be really grateful if you could do so as soon as you can to
ensure your places are reserved before we advertise the meeting more
widely. As you'll see, there is a really nice lineup of talks there. In the
end, we didn't feel it was possible to dedicate separate slots to every lab
in the consortium as has been done in previous years and instead opted to
group the talks thematically, based on the speaker nominations that you
provided while also trying to maintain a good balance in terms of gender
diversity. We're accepting poster submissions and will be selecting 4
additional early career speakers based on those abstracts so there are
still opportunities there for any labs not currently represented to appear
in the lineup. Please do get in touch if you have any feedback on the
webpage itself or on the running of the meeting. Please also feel free to
share the registration link with other labs at your institution who may be
interested in attending. Really hope you can join us for what promises to
be a fun couple of days!
All the best
Redmond

Hello,
Just a quick reminder that we have a YNiC seminar *tomorrow* (Thursday 1st
of June) at 4pm. This will be the last one of the term and will be given by *Dr
Daniel Baker, Dr Lauren Welbourne and Dr Joel Martin.*
*Title:* Non-canonical binocular pathways in human vision
*Summary:*
The classical view of binocular combination is that signals from the two
eyes remain anatomically segregated until they reach V1, where they are
combined. However there are additional locations in the brain where
binocular combination might occur independently of V1, and which subserve
functions other than conscious visual perception. These include the network
of subcortical nuclei responsible for determining pupil diameter, and a
potential direct koniocellular projection from LGN to MT that might process
rapid motion. We know relatively little about how binocular combination
operates in these pathways, so conducted an fMRI study in which five
different stimuli were presented either monocularly or binocularly. The
stimuli include flickering gratings, a flickering disc (intended to
stimulate light-sensitive pathways), and rapidly drifting achromatic and
isoluminant stimuli (intended to target motion pathways). We will report
the results of whole brain and ROI-based analyses.
Refreshments will be provided for those attending the talk at YNiC, or you
can catch it on zoom using the following link:

also note that we have another seminar this Thursday (see details below),
it would be great to see you there!
*YNiC User Inductions*
If you are aware of any new students/staff that will require access

next induction will be on *Friday the 2nd of June, at 13:00*. Please ask
them to contact support(a)ynic.york.ac.uk to sign up.
*Level 0 operator training*
*The next L0 training session will be held on Wednesday the 14th of June,
13:00-15:00. * Please note that users requesting Level 0 training should be
a PhD, RA/Postdoc, or staff, and should already have a project proposal
submitted to YNiC. Please email support(a)ynic.york.ac.uk if you have any
questions or wish to book on to this session. Please note that sessions are
limited to 4 trainees, which will be allocated on a first-come first-served
basis. Training must be booked at least a week before the session date, in
order to reserve the scanner booking.
*Seminar*
The next YNiC seminar will be this *Thursday (1st of June) at 4pm* with a
talk from *Dr Daniel Baker *titled *"Non-canonical binocular pathways in
human vision"*. It would be great to see you here at YNiC, where
refreshments will be available after the talk. You can also use the

The role of localised sleep spindles in adaptive memory consolidation
Summary:
Sleep spindles are 12-15Hz waxing and waning neural oscillations occurring
during non-rapid eye movement sleep. They are believed to be
mechanistically involved in memory consolidation, the strengthening and
stabilisation of recently acquired memories, through inducing LTP and
synaptic plasticity in learning-related hippocampal-cortical networks. A
recent framework proposes that spindle-mediated memory consolidation should
favour so-called adaptive memories, those experiences that are personally
salient or goal-relevant. In this talk, I will present an outline for a
study designed to directly test this hypothesis for the first time. I will
employ a lateralised encoding task and present stimuli to a single visual
field that should create distinct encoding representations in the
contralateral hemisphere. Memory for items in one visual field will be
prioritised for consolidation by being associated with a financial reward
if remembered at a post-sleep test. I hypothesise that during sleep, sleep
spindle activity will be heightened over the rewarded hemisphere (compared
with unrewarded), and that this spindle activity will correlate with memory
for the high-reward items.
See you all there

and spatial cognition*

*Abstract*
The Default Mode Network (DMN) often deactivates to visual input yet it can
couple to visual cortex, and it is composed of multiple subsystems that
might differ in their degree of visual coupling or in the memory
representations that they support. We used a combination of univariate,
connectivity and multivariate fMRI analyses across three samples (combined
N > 250) to investigate the architecture connecting visual cortex to DMN,
and the engagement of visual-DMN pathways in memory-guided decisions across
two domains (semantic and spatial). Participants learned virtual
environments consisting of buildings populated with objects, with half of
the buildings containing objects from a single semantic category allowing
them to associate space with meaning. In a second session, they made
spatial and semantic decisions about these buildings and objects in the
scanner. We found semantic and spatial judgements engaged distinct DMN
subsystems. Frontotemporal DMN regions were primarily engaged by semantic
judgements and showed stronger connectivity to object perception regions in
lateral ventral occipital cortex, while medial temporal DMN regions were
more strongly recruited during spatial judgements and showed stronger
connectivity to medial visual regions involved in processing scenes.
Clusters in angular gyrus and ventral lateral occipital cortex,
topographically situated between these pathways, were implicated in the
integration of semantic and spatial information, suggesting a mechanism for
the interaction of these distinct visual-to-DMN pathways. These results
show how processing streams that capture different unimodal to heteromodal
transformations relevant to conceptual and spatial processing might
interact at multiple levels of the cortical hierarchy to produce coherent
cognition.

Hi all,
We encountered and error with the Siemens MRI scanner today. The
engineers are being booked in to resolver the issue and we hope it will
be a relatively quick fix. We will keep you posted, but as it stand the
system is down as it requires some parts.
More news will follow as soon as we have any,
