[Humor and the brain: neurobiological aspects].

In recent years, a number of studies have been published on cerebral activation induced by funny stimuli. This article provides an overview on the structures involved and findings concerning the neuropsychological faculties necessary for joke comprehension, e.g., working memory and mental flexibility. On the other hand, there are also many aspects of humor, like joke production, that are not neuropsychologically well studied; an overview of current knowledge will be given. In addition, there is little research on the effect of aging on the different aspects of cerebral humor processing.
