Hi everyone
Here's what's going on this week at YNiC:
*Project Presentation - Thursday 4pm:*
This week we have a project presentation from Dr Daniel Kaiser and Matt
Foxwell on Thursday 21st November at 4pm in YNiC open plan, titled:
"Probing effects of scene structure on object perception using TMS". Talks
are followed by refreshments. We hope to see you there!
*Strike Action:*
As you may be aware, UCU have announced an 8 day period of strike action
commencing 25th November. As yet we are not aware of any impacts on
activities at YNiC. Should any impact arise, we will make all efforts to
keep you informed.
*Cluster Output Paths:*
>From Monday 25th November you will only be able to write data to
/scratch/groups, and not straight to /groups. This is already the
recommended best practice at YNiC, but we will be enforcing it from next
week to reduce storage pressure on the /groups drive. Please make sure you
edit any of your scripts that currently save straight to /groups.
*YNiC User Inductions:*
If you are aware of any new students/staff that will require access to YNiC
and/or an IT account, they must attend a YNiC user induction. Our next
induction date will be Wednesday 27th November at 2pm. Please ask them to
contact support(a)ynic.york.ac.uk to sign up.
Hope you have a good week!
Kind regards

Hi everyone
This afternoon we have a guest speaker at YNiC - Dr Melanie Burke from the
University of Leeds. She will be presenting at *4pm in YNiC open plan*.
Refreshments will be provided after the talk. Please find the title and
abstract below:
*Title:* “Inducing neuroplasticity in the prefrontal cortex: a preliminary
investigation into the effects on the brain and cognition.”
*Abstract:* Theta burst stimulation (TBS) is a form of repetitive
transcranial magnetic stimulation (rTMS) that can be used to increase
(intermittent TBS) or reduce (continuous TBS) cortical excitability. The
current study used iTBS in 18 adults, to investigate the causal role of the
dorsolateral prefrontal cortex (DLPFC) during the performance of four
cognitive functions: attention, inhibition, sequence learning and working
memory. Participants performed the cognitive tasks both before and after
iTBS stimulation and functional near infra-red spectroscopy (fNIRS) was
monitored throughout. Preliminary findings of brain activity before, during
and after TBS, alongside eye movements responses to the cognitive tasks
will be presented.
We hope to see many of you there!
Kind regards

*Net salary:* 2700e per month with some teaching
*Duration:* 2 years
*DESCRIPTION *
Optimal distribution of attention is a key issue in our everyday-life
multitasking activities. It relies on a tradeoff between exploration and
exploitation attentional policies to select and maintain attentional focus
on the relevant streams of information while remaining alert to unexpected
changes. Several studies have identified some neural correlates supporting
such attentional dynamics. For instance, top-down and bottom-up types of
attention are respectively delineated by the dorsal and ventral neural
networks that are in close interaction with the anterior cingulate cortex
for resource allocations. Efficient divided attention results in an
enhancement of task relevant networks activity via cross frequency coupling
in the theta and gamma band and enhancement of secondary task networks
activity at different phase to that of primary task networks. However, when
task demand exceeds mental capacity, the homeostasis between the ventral
and dorsal pathways is disrupted, leading to the suppression of non-primary
task relevant network (via increased alpha oscillations) and decreased
frequency coupling between theta and gamma in primary task networks.
Although this shielding mechanism can prevent from mental overload and
distractions, missing critical information can have devastating
consequences in real-life scenarios such as driving or operating an
aircraft (eg. auditory alarms).
The candidate is expected to design and conduct experiments to investigate
the shift from efficient to non-efficient divided attention between the
visual and the auditory modality. These experiments will be conducted 1) in
the lab using fMRI and high-density 2) under highly ecological conditions
with portable EEG.
The candidate is expected to perform state-of-the-art analyses including
effective connectivity and to apply inverse reinforcement learning (IRL)
technics to 1) estimate the efficient (optimal) and non-efficient
(sub-optimal) policies with respect to best expected distribution of
attention. 2) to predict long-term attentional efficiency.
The ideal candidate will have a strong background in Neurosciences, brain
imaging (EEG or/and fMRI/MEG), signal processing, artificial intelligence
for automated learning and planning. She/he will have to work in strong
collaboration with the three other researchers (2 PhD students, 1 post doc)
funded by the ANITI program. This research will be conducted within the
stimulating environment of Neuroergonomics lab at ISAE-SUPAERO (25
researchers), the Artificial and Natural Intelligence Toulouse Institute.
The candidate will have the opportunity to have a long stay in Cinet
(Osaka/Japan) at Daniel Callan’s research department to conduct the fMRI or
MEG experiment.

Hi everyone
Here's what's going on this week:
*YNiC Monthly Science Social:*
We're kicking off the first Science Social session with a talk by Andre on
DTI scanning; this should be a really interesting introduction to this type
of scan, plus we'll be providing pizza, so we hope to see many of you
there! The session will be held in YNiC open plan this *Thursday 7th Nov at
4pm*. For a list of the upcoming Thursday sessions, please visit
https://www.ynic.york.ac.uk/events/thursday-sessions.
*Level 0 operator training:*
The upcoming Level 0 training session this week is now fully booked. Our
next scheduled training session will take place on *Wednesday 11th December
at 2pm-4pm*. 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, and include which scanner you
wish to be trained on. *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.*
*It is recommended that all Level 0 operators attend an 'Emergency First
Aid at Work' one-day training course.* This is currently a requirement for
Level 1 operators, and will also be required for Level 0 operators soon -
we will enforce this requirement from March 2020, to give current Level 0
users time to arrange the training course. Courses should be organised by
the project PI with a relevant training provider (e.g. St Johns Ambulance,
Red Cross); these providers can also run group training sessions (8 or more
people) on-site, so labs may wish to coordinate their operators to all
attend training on the same day, at a location of your choice.
*YNiC User Inductions:*
If you are aware of any new students/staff that will require access to YNiC
and/or an IT account, they must attend a YNiC user induction. Our next
induction date will be Wednesday 13th November at 2pm. Please ask them to
contact support(a)ynic.york.ac.uk to sign up.
*Christmas Closure:*
We'd like to give you advance warning that YNiC will be closed to users
from the week commencing 16th December, and will re-open in the New Year,
on the 3rd of January.
Hope you have a great week.
Cheers

Hi everyone
We have quite a few notices for you today, including a chance to *win a
bottle of wine* if you read until the end!
*Level 0 training:*
We have reviewed the Level 0 training process, and now, in addition to the
training session, Level 0 trainees will also be observed for a minimum of 3
scan sessions, until we are satisfied that they meet operator requirements
(these scans must be booked in operator-covered slots). We therefore
recommend that you only book onto a training session when you have ethical
approval for a project, and intend on scanning within the next couple of
months.
Our next scheduled *Level 0 training session *is at *2pm on 6th November*,
please email support(a)ynic.york.ac.uk to book on to this session, and
include which scanner you wish to be trained on. Training will take up to
two hours. *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.*
*First Aid Training for Level 0 operators:*
It is recommended that all Level 0 operators attend an 'Emergency First Aid
at Work' one-day training course. This is currently a requirement for Level
1 operators, and will also be required for Level 0 operators soon - we will
enforce this requirement from March 2020, to give current Level 0 users
time to arrange the training course. Courses should be organised by the
project PI with a relevant training provider (e.g. St Johns Ambulance, Red
Cross); these providers can also run group training sessions (8 or more
people) on-site, so labs may wish to coordinate their operators to all
attend training on the same day, at a location of your choice.
*User Inductions:*
If you are aware of any new students/staff that will require access to YNiC
and/or an IT account, they must attend a YNiC user induction. Our next
induction date will be Wednesday 30th October at 2pm. Please ask them to
contact support(a)ynic.york.ac.uk to sign up.
*Monthly Science Social Seminars:*
On the first Thursday of every month YNiC will be hosting a 'Science
Social' at 4pm in YNiC open plan. This will include a talk or discussion
on topics that will include imaging methods, software, and analysis
techniques. We also encourage users to volunteer to present if they would
like to share something that they think may be of interest to other users.
Pizza and drinks will be provided!
*Halloween 'Scary Slice' Game:*
This week at YNiC you will have a chance to win a bottle of wine by
correctly matching the staff member to the MRI slice (a coronal slice of
the face that is suitably scary and Halloween-y). Images will be up on the
white board in open plan until the end of the day on Thursday. The person
that correctly matches the most images will be awarded the bottle of wine -
good luck!
Hope you have a great week!
Kind regards
