ABSTRACT: Investigating respiratory acts using motor imagery has the
advantage that motion artifacts are much less likely to
occur. To test whether motor imagery of voluntary coughing
shows similar spatiotemporal activity patterns as
compared to overt coughing, 12 participants underwent
functional MRI scanning performing both tasks.
We analyzed the data using a pattern classifier, that is,
a support vector machine. Results showed that during
imagined coughing, a number of brain areas reported
previously to be involved in respiration showed more
similarity in their spatiotemporal activity patterns with overt
coughing than with a resting baseline. We conclude that
motor imagery can be a suitable paradigm to investigate
respiration, and that support vector machine analysis is
potentially more sensitive and specific than a standard
univariate analysis.
