Starting stage Center the image using the "arrow cross" in the top black strip! The following two steps show the division of the cerebellar cortex into different layers (step 1) and the cerebellar cortex nerve cell types (stage 2). It is important that you can place the image the way you want it on the Stage and use different magnifications (Help). Do not forget about the identification function

Step 1.

The different layers of the cerebellum. Figure A shows a photo of a split cerebellum. The cut (a sagittal incision) runs through the vermis. Notice how strongly folded the surface of the cerebellum is. Cerebellar leaves (folia cerebelli) appear clearly. Figure B shows a photo of a thinly colored sagittal section from the top of a folium (box in fig. A) seen through a microscope. The distinct blue dots are the cell bodies of Purkinje cells. Locate the different layers in Fig. B.Activate the Cerebellar bark layer and unfold the list. Deselect from top to bottom or turn off all and check from top to bottom.

Step 2.

Cerebellar cortex nerve cell types with signal flow in and out of the cortex. The image wants to schematically illustrate the different neuron types of the cerebellar cortex as well as inward-conducting and outward-conducting nerve fibre types. Activate the different lists in turn. Folded out the current list. Select Extinguish all, and then tick the different structures from the bottom of the list upwards. Investigate different combinations of inhibitory and excitatory cell types, their interrelation and outflows and inflows of nerve signals. Structures with excitatory properties are green/blue-colored. Structures with inhibitory properties are red/yellow in color. NB! The image does not take into account the relative distribution of the different cell types in the master plane. In fact, the dendrite trees of the Purkinje, basket, star and Lugaro cells are flattened from the sides and spread out in the sagittal plane, perpendicular to the transverse direction of the parallel wires.
