Zusammenfassung:
The size of the neocortex and its morphology are highly divergent across mammalian species. Several approaches have been utilized for the analysis of neocortical development and comparison among different species. In the present protocol (Note: This protocol requires basic knowledge of brain anatomy), we describe three ex vivo neocortical slice/tissue culture methods: (i) organotypic slice culture (mouse, ferret, human); (ii) hemisphere rotation culture (mouse, ferret); and (iii) free-floating tissue culture (mouse, ferret, human). Each of these three culture methods offers distinct features with regard to the analyses to be performed and can be combined with genetic manipulation by electroporation and treatment with specific inhibitors. These three culture methods are therefore powerful techniques to examine the function of genes involved in neocortical development.
