Dear All,
I'm pleased to announced that we're about to start a new study which will
look at the relationship between the size of the hippocampus and performance
on a topographical memory task.
The aim is to make use of MRI data collected in connection with previous and
ongoing studies. We are looking to make contact with potential participants
(healthy adults, aged 18-50) who have already had an MRI scan at YNiC or who
will have one over the next 6-9 months. An additional constraint is that
they should be available to take part in a brief (15-20 minute)
psychological test later in the year.
If you have already or are about to conduct a study with suitable
participants and are willing to help, we would like to hear from you so that
we can begin the process of contacting subjects and identifying studies in
which they have participated. We aim to make this as easy for you and the
potential participants as possible. There is a also a panel of volunteers
who have agreed to be approached regarding future studies at YNiC, and we
intend to approach these via the Director. To respond, please use the link
below (please be careful not to "reply to all"!):
mailto:t.hartley@psychology.york.ac.uk;rch504@york.ac.uk?subject=hvt:I-have-
a-study
You may yourself have had a scan and be interested in participating - if so,
please contact us, and we can then begin the process of tracking down your
scan and obtaining permission to analyze the data. There is no need to make
a firm commitment at this stage, and as with all such studies, you would be
free to withdraw at any time. If this fits you, please use the following
link to reply to this message:
mailto:t.hartley@psychology.york.ac.uk;rch504@york.ac.uk?subject=hvt:I-have-
a-study
Further information for potential participants is available at:

Dear YNiC Users
We would like to get your feedback on when would be the most convenient
time to run training sessions.
Please can you take a few minutes to tick some boxes and make comments
on the online form at
https://www.ynic.york.ac.uk/user-resources/training-survey
We will collate the information in two weeks time
thanks

Dear ynic-users
It is good to see that many of you are now using the online booking form
for MEG and MRI.
https://www.ynic.york.ac.uk/user-resources/booking
We hope the new procedure is easier than the old method of using email
and/or phone.
There is a small problem though which we would like to bring to your
attention. When you use the online form, you should still wait for
confirmation from Claire Fox by email that your session has been booked.
This is because several people could, in theory, attempt to book the
same hour.
Another problem is that some people are attempting to book a session at
night for the next day. This is not practical as we need to ensure that
an operator is available, that the scanners are available and that all
stimulus delivery issues, ethics, and consent are all in place.
Please can we ask users to try and book their sessions before the
Thursday of the week before they wish to use the scanners.
Of course we do not want the scanners to be idle and the resource to be
wasted, so, if you want to make a last minute booking and all the
practical aspects of scanning are in place, then please ring Claire to
discuss the possibility of using the scanners. The key thing then will
be availability of operators.

Tomorrow, the annual one day resuscitation course is being run within
YNiC. This is primarily for operators and staff at YNiC but if you feel
that you might benefit from attending this course then there are a few
places available for ynic-users. If you would like to attend please
email claire.fox(a)ynic.york.ac.uk
It will start at 9.30 and last until mid afternoon.

Dear all,
when new users arrive at YNiC, some would like to practice using data
analysis scripts before they record their own data. As such, we would
like to document some of the paradigms that have already been recorded.
We would not want to know in detail the specifics of your project, just
the basics to allow for a sensible analysis.
For example, the following may be enough:
"In the data for project Pxxxx, responses were recorded in continuous
mode to visual stimuli. There were four conditions which had the
respective trigger codes 4150, 4152, 4154 and 4156. Triggers 4150 and
4152 had a group code of 2, and triggers 4154 and 4156 had group codes
of 4. Participants made responses to some trials, which have a response
code of 32. Suggested epochs for data analysis are 150ms pre-trigger and
900ms post-trigger. Data was recorded for participants Rxxxx, Rxxxy ...
Rxyyx."
With this information new Users could run a trial analysis without any
necessary knowledge of your hypothesis, but enough information about
your stimulus parameters to run practice analyses on your data.
If you we be happy to provide this information about your data we would
be most grateful. We would then put this in some shared space for all
Users to access. If however you would like to give a more detailed
account of your experiment, then this could contribute towards the
initiative that Tony prompted in the email copied below.
With thanks,
Michael

Copy of mail from Tony Morland date 25th October.
Dear All,
Since the first beamforming course a number of people have been asking
questions like;
What can beamforming really do?
If I do this and get that, what does it mean?
Is beamoforming precise enough to distinguish between activity in brain
area A and B?
If I do X will it result in data that can be analysed with beamforming?
Can virtual electrode traces allow latencies to be measured in brain areas
A and B and do they make sense?
If I filter in this frequency band rather than that band why do I get this
result?
The answers to many of these questions are empirical and although Will et
al have been striving to test, retest and validate the methods, there will
always be questions that can't quite be answered unless more data is
acquired/analysed. It appears necessary therefore to start bench marking
the beamforming methods that are available. The aim is to undertake a
series of empirical studies that will reflect, in broad terms, the types
of paradigm used by investigators. My personal preference would be for a
set of basic experiments to be devised for which results are predictable
and could be compared with previous research. I accept that this is a
conservative aim, but the data sets acquired are likely to be the most
informative about the capabilities of the beamforming analysis tools. The
data acquired would also offer us an excellent resource for training any
researchers wishing to undertake investigations using beamforming.
Before devising new experiments it would be worth reviewing previous
studies undertaken at YNiC to see whether they can be used to bench mark
the beamforming methods. To this end, I would be grateful if you could
provide me with details of data that you think are suitable for bench
marking beamforming. The most helpful form for the information would be
the following:
Project Number and Title
Number of participants and their registered numbers
Paradigm used
Relevant research (the study replicated)
Predicted outcome
What you want to test with beamforming
Ethical concerns/limitations concerning use of the data
I will review the forthcoming information and after that will arrange a
brainstorming session on how best to move things forward.
Thanks
Tony
Dear Users,
further to the email sent recently about the format of booking requests,
Users may book scan time via a new on-line booking form.
https://www.ynic.york.ac.uk/user-resources/booking
However to cancel a booking please send the following request to
bookings(a)ynic.york.ac.uk :
CANCEL
Date: 31st October 2006
Time: 00.00
Type of Scan: structural MRI
Project ID: P0666
Participant ID: R0000
Unfortunately, verbose requests can lead to ambiguities and increase the
chances of errors. Please avoid the following style of request:
"This is just a request to cancel the time for one subject on Monday of
this week (my subject is on holiday LOL!) and then re-book them in to
another slot next Friday, for some time in the afternoon (don't mind
when), with all the same information, but an amendment to the Stimulus
Code from P0666et to P0666aa."
Should you need to re-schedule a subject, please simply send a CANCEL
request as shown above, and then re-book some new time via the website.
Thanks,
Michael
