Humor ernst genommen

Zusammenfassung

In dieser Übersichtsarbeit werden zunächst Befunde zu Störungen der Humorwahrnehmung nach zerebralen Läsionen dargestellt, die insbesondere auf eine wichtige Rolle des rechten Frontallappens hindeuten. Die bisher existierenden bildgebenden Studien zur Humorwahrnehmung haben mit unterschiedlichen Methoden verblüffend übereinstimmende Befunde erbracht, zeigten allerdings keine Aktivierung des rechten Frontallappens. Es fand sich eine Beteiligung des linken temporoocipitalen und inferioren lateralen frontalen Kortex bei der Humorwahrnehmung und eine Aktivierung des limbischen Systems (insbesondere der medialen Temporallappen und Nn. accumbens beidseits) bei der Erheiterung. Der rechte frontale Kortex hingegen zeigte eine Deaktivierung. Die neuronale Basis des Lächelns, die bei neurologischen Patienten auftretenden Störungen und neuronale Grundlagen des ansteckenden Lächelns werden abschließend dargestellt.

Summary

This review starts with summarizing the literature on impairments of humour perception after brain lesions, which points to a prominent involvement of the right frontal cortex. Then it demonstrates that recent functional imaging studies despite varying methods yielded surprisingly coherent results, but no activation of the right frontal cortex with humour perception. It is postulated that the left temporooccipital and inferior lateral frontal cortex are activated with humour perception, the limbic system (in particular the medial temporal lobes and Nn. accumbens bilaterally) with exhilaration and that deactivation of the right frontal cortex takes place with smiling. The neurological basis of smiling including its contagiousness and its impairments in neurological patients is described.
