Fronto-occipital head length ?? cm. Enlarged.

(Anatomical Collection in Basel.)

The brain is shown in situ, DA6 the location of each Ab- sections are marked with the skull and the skull base. the dura mater and the tentorium cerebelli are visible. The Hemisphreres shows the first hint of furrows perpendicular to the center of the island, GE directed to the central sulcus, precentral sulcus and then the slightly right and below the beginning of the superior frontal sulcus. In the lower section the fossa lateralis cerebri (Sylvius) is the embryonic olfactory gyrus lateralis and bent his course to the visible tip of the temporal lobe.

Fig. 618. Gehirn eines menschlichen Fetus vom 6« Monat

Fronto-occipitale Kopflänge ^ cm. Vergrößert. (Anatomische Sammlung in Basel.)

Das Gehirn ist in situ dargestellt, so da6 die Lage der einzelnen Ab- schnitte zu dem Schädeldach und der Schädelbasis kenntlich werden. Die Dura mater encephali und das Tentorium cerebelli sind sichtbar. Das Hemisphärium zeigt die erste Andeutung von Furchen: senkrecht auf die Mitte der Insel ge- richtet den Sulcus centralis, dann den Sulcus praecentralis und etwas nach rechts und unten der Beginn des Sulcus frontalis superior. Im unteren Abschnitt der Fossa cerebri lateralis (Sylvii) ist der embryonale Gyrus olfactorius lateralis und sein gebogener Verlauf zur Spitze des Schläfenlappens sichtbar.
