[Area mesencephalica on the raphe and its importance. (Stereometric reconstruction in cat) (author's trnsl)]

The cat's mesencephalic raphe, caudally extended to the locus ceruleus and rostrally to the habenulo-interpedunculary area, was reconstructed with foamy-plastic plates in a stereotaxis ensemble of the brainstem. This reconstruction serves as an important reference to the topography and for interpreting the functional background of the stereotaxic lesions accumulated in the last 5 years. The alterations of the lung's alveolar interstitium after the nervous lesions, were classified in different groups of common evolution.
