Sous ces conditions on constata: que le système nerveux autonome et avec ceci l'hypothalamus peut être converti d'une manière analogue si par irritation adéquate du nerf sciatique ou de l'hypothalamus une augmentation ou une chute de la pression artérielle est provoquée. The relationship between nonverbal anxiety and stuttering adaptation. Within the group of stutterers, the more extreme increases in arousal specifically increases in measures reflecting sympathetic arousal were correlated with the occurrence and increased severity of disfluent speech.

The resulting simultaneous ergotropic and trophotropic discharges impinging on the cerebral cortex are thought to induce abnormal emotions and behavior. Review of Results and Clinical Application Chapter 9. On the Psychophysiology of Arousal, 13; 4. Effects of sympathetic nerve stimulation on intra-oral mechanoreceptor activity in the cat. The posterior hypothalamus and the central end of the sciatic nerve have been stimulated in anesthetized cats before and after bleeding and also after reinjection of blood or Dextran.

The findings made were these: 1 In early asphyxia and immediately after the readmission of air or oxygen after a period of 60 to 90 seconds of asphyxia there is a phase of rising blood pressure and heart rate which indicates increased sympathetic discharges. Chicago: National Easter Seal Society. Nevertheless, the reactivity of the visual and auditory cortex to specific afferent impulses is retained.
Significant correlations were found for the intervals prior to, during, and after speech. The Transition of Sympathetic to Sympathetico-Adrenal Activity, 191; V.

Zusammenfassung Versuche wurden an Katzen in oberflächlicher Narkose ausgeführt, bei denen die Reaktivität des Hypothalamus auf elektrische Reizung bestimmt wurde, nachdem der Blutdruck durch Injektion von Acetylcholin, Mecholyl oder Histamin erniedrigt oder durch Injektion von Noradrenalin erhöht worden war.

Résumé Des expériments furent faits sur des chats sous narcose superficielle, dans lesquels la réactivité de l'hypothalamus à l'aide d'irritation électrique après diminution de la pression artérielle par injection de l'Acétylcholine, du Mécholyl et de la Histamine ou après augmentation de cette pression par injection de la Noradrénaline fut marquée.
