[Eeglablist] Single trial analysis

[Tarik S Bel-Bahar]

Hello Gian, some quick notes below, best wishes!


************BEGIN NOTES FOR GIAN

There are several papers out there on single-trial metrics, both in
mainstream EEG journals, imaging journals, methods journals, as well as
IEEE/BCI/neurorehab/neuro-engineering journals. This is an important topic
as the field ihas been moving away (more quickly in recent years) from
"averaged" responses to understanding variability across trials, the
validity of using single trials, etc.. Take a good look through those
publications for good ideas. If you have trouble finding those, just look
for any articles in last 10 years that mention single-trial and EEG in
their title or abstract, and review them all. Then you can become an expert
on what's been done, what's not been done, and contribute to this area of
EEG methods/metrics. Note that the BCI field has also dealt extensively
with working with single-trials and there are great reviews out there
summarizing the efficacy of those methods, and the accuracy of various
machine/classifier approaches to working with BCI-related protocols.

I've include a range of mostly recent papers (including several reviews
focused on the single-trial topic) below. You can find them all easily on
Google Scholar. Note there are many other papers that I am not listing
here. When you have developed a good list of ideas/methods/etc... please
consider sharing them with the list as it will also help other users make
benefit of the single-trial brain dynamics, and make informed decisions.

Within eeglab, you can certainly pull out single trial metrics, and you
already have important issues/caveats in mind. As you know eeglab
emphasizes the power and usefulness of ICA, so one thing you can do is stay
in ICA space, use good neural IC components, and focus on IC-resolved
single-trial metrics. In fact the developers of eeglab had a strong focus
on making it easier to visualize and work with single-trial brain dynamics,
as there's where some of the most interesting "action" happens. In other
words, humans naturally function in terms of single-trials, it's only
science that's needed to start with averaged responses (though, again, this
has been changing for at least the last two decades). When you start your
trials of single-trial analyses with eeglab, you can send more focused and
specific questions to the list, especially if you bump into problems of
implementation in terms of the eeglab gui and scripting your methods.

I've also seen some paper that essentially drop all ICs except the one of
interest, and then looks at the rebuilt channel-level data based on that.
This is one way of many to "single-out" the activity of interest at each
trial. Overall, you would want to pull/use single-trials that really match
some prototype ERP, but you would have to deal with the fact that ERPs are
usually averaged across trials. Explore the ERPimage technique in eeglab at
least to get a sense of how you can visualize data across all your trials,
including sorting them in various ways. Another set of issues one would
have to deal with is cleanliness of the data, method of preprocessing,
individual differences in signal quality, variation in ERPs across single
trials within each participant, and the validity of the protocol you have
used to generate the ERPs in question, including the quality of your
specific implementation of that protocol.
