[Functional speech system disorder in stuttering].
The author studied the EMG or orbicular muscles of the mouth, respiration, pulse frequency, SGR, EEG registration during the pronunciation of words out loud and to onself, during the orientation reflex to sound and verbal stimuli. These indices were mainly studied during autogenic training in patients with neurotic stuttering (the 1st group) and in patients with organic lesions of the CNS and stuttering (the 2nd group). The first group of patients demonstrated formed motor verbal sterotypes. A disturbance of the correct programme of action in the functional speech system is due to an increase of the activity in the limbico-reticular system. The 2nd group exhibits the absence of the correct programme of action in the accomplishment of motor speech stereotypes. The abnormal programme of the activity is formed from the beginning of the speech activity and is fixed in the ontogenetical memory.
