Zusammenfassung
Emotionen sind neben der Sprache eines der wichtigsten menschlichen Kommunikationsmittel. Insbesondere der Gesichtsausdruck trägt zu einer schnellen emotionalen Verständigung bei. In einer Vielzahl von neurophysiologischen und funktionell bildgebenden Untersuchungen konnte gezeigt werden, dass verschiedene neuronale Strukturen an der Emotionserkennung in Gesichtern beteiligt sind, wie z. B. visueller Kortex, fusiformes Gesichtsareal, Amygdala, orbitofrontaler Kortex, supratemporaler Gyrus, Basalganglien und somatosensorischer Kortex. Das Zusammenspiel dieser Strukturen ist jedoch noch größtenteils nicht entschlüsselt. In dieser Arbeit wird besonders auf die Rolle des somatosensorischen Kortex eingegangen, der theoretischen Überlegungen zufolge für eine neuronale Simulation der betrachteten Emotion zuständig ist und somit einen entscheidenden Beitrag zu Wahrnehmung, Interpretation und Mitfühlen der Emotionen anderer Menschen leistet.
Abstract
In addition to language, emotions are one of the most important means of communication. In particular, facial expression mediates rapid emotional comprehension. Neurophysiological and functional neuroimaging studies have revealed a number of cerebral structures involved in recognition of emotions from facial expressions, such as visual cortex, amygdala, orbitofrontal cortex, basal ganglia, and somatosensory cortex. The dynamic interactions between these structures are largely unknown. This paper primarily reviews the role of the somatosensory cortex for emotion recognition. The hypothesis has been put forward that the somatosensory cortex is involved in simulating perceived emotions thereby contributing importantly to perception and interpretation of as well as empathy with another personŽs feelings.
