Abstract

We investigated the cortical connectivity
patterns that arise in subjects with spinal cord injury
(SCI) during attempted hand and arm movements
using multivariate autoregressive (MVAR) models and
electroencephalographic (EEG) signals. The MVAR
models were fitted using multiple trials from multiple
subjects in order to capture general connectivity
characteristics during different type of attempted
movements. Based on the results we detected two
main sources of information: the somatosensory and
the primary motor area. Changes in directional
connectivity between different regions before and after
cue onset were found to be informative in terms of the
type of movement attempted by the SCI participants.
