Starting stage. Set up the scene Start by UNCHECKING according to the instructions below under the heading "In the image". Then center the image! Click 2x on the right arrow in the arrow cross and 1x on the bottom arrow. The figure here shows the central nervous system as seen from behind according to. the layout of the picture "Central Nervous System Nuclei". The slightly greyed areas of the spinal cord, brainstem and midbrain mark nuclei/neuron groups connected to the Cerebro/Pontocerebellum (lateral hemispheric zone of the cerebellum). Place and move the image around the way you want it on the screen and use different magnifications (Help) .

Step 1.

Step 1. Locate nucleus/neuronal groups that receive nerve signals from and transmit nerve signals to the Cerebro/Pontocerebellum (the lateral hemisphere zone) and the dentatus nucleus. Light the Cerebro/Pontocerebellum and Dexlatus Dentatus. Activate list A, unfold it, select "turn off all" and light the steps in the list from top to bottom. Then collapse the list A and deselect it. Continue in the same way with list B.Om you light A together with B, and you will see that in several cases a core area can function both as a signal receiver and as a signal transmitter.

Step 2.

Step 2. LEFT Cerebro/pontocerebellum (lateral hemisphere zone) with connected nucleus dentatus. OUTFLOWS of nerve signals. The cerebro/pontocerebellum (lateral hemisphere zone, list 1v) and nucleus dentatus (list 2v) are already marked (lit) on the left side. Leave them lit as you examine the rest of the step! The step includes fifteen lists: 1v to 15v (v = left). Light and unfold the lists 3v to 15v, in order of numbers, identify the different entries (extinguish/ignit) and link to the database if necessary. It is probably wise, until 5v, to first take each list individually and extinguish the just reviewed list before going on the next. The lists 8v&11v are best investigated by first clicking on "turn off all" and then light the list from bottom to top! Then you can start over from 5v and leave the lists lit up as you go, to get a picture of the total signal output. Do not forget to move around in the image and to vary the magnification. NB! The identification function!

Step 3.

Step 3. LEFT Cerebro/pontocerebellum (lateral hemisphere zone) with connected nucleus dentatus. INFLOWS of nerve signals. The cerebro/pontocerebellum (lateral hemisphere zone, 1v) and nucleus dentatus (2v) are already marked (lit) on the left side. Leave them lit as you examine the rest of the step! The step includes four new lists lists: 12v through 15v (v = left). Light and unfold the lists 12v to 15v, in turn, identify the different entries (extinguish/ignite) and link to the database if necessary. It is probably wise to first take each list individually and extinguish the just reviewed list before moving on to the next. List 15v is extinguished gradually from top to bottom. The width of the different colored connecting bands (cortex to pons) in list 15v wants to give an idea of the relative amount of nerve fibers in each connection. (Ref: Ramnani, N. The primate cortico-cerebellar system: anatomy and function. Nature Rev. Neurosci.7, 511-522. 2007.)Then you can start over from 12v and leave the lists lit up as you go. This provides a picture of the collected pathways of nerve signals to the Cerebro/Pontocerebellum (lateral hemisphere zone) and the dentatus nucleus.

Step 4.

Step 4. LEFT and RIGHT Cerebro/Pontocerebellum (lateral hemisphere zone) together with the respective dentate nucleus. OUTFLOWS and INFLOWS of nerve signals. The cerebro/pontocerebellum (lateral hemisphere zone; 1v,1h) and nucleus dentatus (2v,2h) are already marked (lit) on both sides! The step comprises thirty (30) lists: 1v through 15v and 1h through 15h (v = left, h = right). The purpose of the step is to build up the picture of all outflow and inflow pathways for nerve signals between the Cerebro/Pontocerebellum (lateral hemisphere zone) with the dentatus nucleus and the rest of the central nervous system. The easiest way is probably to start with the right side (lists 3h to 15h, see the headings!) and do the same as you did in Step 2 and Step 3 (left side). Then light the lists 3v to 20v. The confusion that has then emerged can then be dissected by extinguishing and lighting in different combinations. You can also, with slightly larger magnification, mouse click directly on the structure you are wondering about and thus get a name and information from the fact base. It is now free to mix and experiment!! When all lists have been extinguished, try lighting 1v to 4v, 9v, 10v, 12v!!!! Notice the inhibitory signal outflow from the dentatus nucleus that travels directly to the olivainferior complex and the excitatory signal flow that takes the "detour" over the small cell part of the nucleus ruber and is relayed from there to the olivainferior complex.
