Abstract:


Some of the highest impact work in the field of neuroimaging and
cognitive neuroscience has been characterized by its incorporation
of methods that are at the cutting edge of what is possible
technologically. The field of neuroimaging as a whole has been pushed
by individuals and groups that have used pressing questions to
leverage significant methodological advances. Examples such as fMRI
retinotopy and fMRI - adaptation paradigms immediately come to mind.
In this talk I will discuss some of the latest developments in
technology and address how they are or might be incorporated into the
framework of cognitive neuroscience questions.

In recent years, increased attention has been placed on improving
methods for extracting spatial and temporal information from the fMRI
time series. In addition, methods for obtaining blood oxygenation
sensitive MR images at higher resolution, higher speed, and higher
signal to noise have challenged the state of the art in post
processing and interpretation. Processing methods, fMRI signal
interpretation, and applications have co-evolved with that of imaging
technology. In this lecture, I will outline some of this progress and
highlight some of the most exciting recent advancements from the NIH
and elsewhere that involved the following: high resolution fMRI, high
field strength, parallel imaging, multivariate analysis to extract
spatial pattern information, time series fluctuations, "baseline"
activity and signal change dynamics. The goal of this lecture is to
argue that fMRI methodology is still in flux and that the
sophistication of the questions addressed using the technique will
likely advance as the technology, methodology, and interpretation of
the signal continue to advance.
