Abstract

This paper reports on preliminary results of finding sensorimotor cortex spatio-temporal residual activation during attempted motion of paralysed limbs in spinal cord injured (SCI) patients. Our aim is to make use of such activity to control non-invasive brain-computer interfaces where the association of movement imagery and device control should lead to reduced device training times. Application of a continuous wavelet transform to EEG records is used to illustrate the spatio-temporal cortical activation recorded when the subjects with SCI performed imaginary movements.
