Zusammenfassung
Das somatosensorische System verarbeitet Informationen aus Haut-, Gelenk-, und Muskelrezeptoren und dient damit primär der Wahrnehmung sensorischer Qualitäten wie Druck, Berührung, Schmerz und Temperatur. Die Integrität dieses Systems ist eine notwendige Voraussetzung für das Verarbeiten komplexer Stimuli, z. B. für das Erkennen dreidimensionaler Strukturen und Objekte (Stereognosie). Weiterhin spielt der somatosensorische Kortex eine fundamentale Rolle bei der Erfassung von Bewegungsinformation (Kinästhesie) und der Wahrnehmung der Arm- und Handposition im Raum (Propriozeption). Daher besitzt das somatosensorische System vor allem mit dem motorischen System enge anatomische und funktionelle Verflechtungen. Funktionell fasst man beide Systeme auch als »sensomotorisches System « zusammen.
