The motor mechanism of some types of epilepsy.

In most cases it is very difficult to find a correlation between cortical or subcortical electrical and clinical electromyographical activity during epileptic fits. This difficulty arises not only from the mechanism of epilepsy, but from the mechanism of the motor system itself. In our previous studies (Toth 1972, Toth, Zarand, Lazar 1974) we have found that the direct connection between the stimulated site of the central motor system and the answering muscles depends on many conditions. The main conditions are: the intensity, the frequency of the stimulus and the functional state of the motor system, rest activity and the transitional states.
