Abstract

We used model independent multi-dimensional vector analysis of evoked responses recorded with two seven channel magnetometers and multi-variate statistics to detect changes over time in the source distribution. Furthermore, we found visual inspection of the vectors’ magnitude and direction a simple way to determine a responses’ important features. Donchin (1966), working in time domain pioneered the application of multi-dimensional analysis to evoked potentials. llmoniemi et al., (1988) applied multi-dimensional analysis to magnetic recordings of spontanteous activity.
