Abstract
The block and event-related designs have been commonly used in functional
magnetic resonance imaging (fMRI) studies to investigate human visual and
auditory systems. The signal to noise ratio is greater with the block design
than with the event-related design, and data process is also easier with the
block design. There are several scientific arguments on a choice between
design paradigms to study human brain functions. In this talk, I will review
the statistical procedures of analyzing fMRI data, and give real data
examples to illustrate the scientific questions that can be addressed via
different experimental designs. Finally, I'll comment on the recent research
of using machine-learning techniques to predict mental states, and of
investigating the default mode of brain functions.
