✦ Synopsis
Many subjects have a negative spike in the beginning of a saccade in electro-oculographic signals.
The amplitude of the spike depends on the location of the electrodes. The spike distorts the saccades and causes errors in the parameters. The saccade spike can assist in the identification of small saccades. A syntactic technique based on formal languages and parsing is presented which looks for spikes from the electrooculographic signal. For calculation of the algorithm, saccades from the photoelectric signal have been concurrently recorded and compared with the electrooculographic signal.
