Starting stage. Set up the stage. Uncheck 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 shows the central nervous system as seen from the back (dorsal. Compare with the layout in the picture "Central nervous system nuclei". Place and move the image around the way you want it on the screen and use different magnifications (Help) .

Step 1.

Step 1. SUMMARY. Outgoing and incoming signaling. Here all the outward and input connections between the vermiszone and the nucleus fastigii on the one hand and the rest of the central nervous system on the other are illustrated. The contact system can best be described as "astonishingly well developed" and not a little complicated. You can try to design the contact system yourself in step 5!

Step 2.

Step 2. Locate core areas/neuron groups that receive nerve signals from and transmit nerve signals to the vermis and nucleus fastigii. Light the nucleus fastigii and vermiszon. Enable 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 3.

Step 3. Outflow pathways of nerve signals from the left vermis zone and left nucleus fastigii to receiving nuclear groups. The nucleus fastigii and vermiszone are already marked (lit) on the left side. The step includes eleven lists: 1v to 11v (v = left). Light 1v and 2v. Unfold the lists, identify the different entries (turn on/off) and use the links if necessary. Then leave 1v and 2v lit. Go through the rest of the lists (3v - 11v) in turn. The lists 3v and 8v are quite extensive. Here it is best to first tick the list, unfold it, mark "extinguish all" and light from the bottom up! It is probably wise to first take each list individually and turn it off before moving on to the next. Then you can start over from 3v 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. (Help) . NB! The identification function!

Step 4.

Step 4. Inflow pathways of nerve signals to the left vermis zone and left nucleus fastigii. The nucleus fastigii and vermiszone are already marked on the left side. The step comprises eleven lists: 12v to 22v. Unfold the lists in turn, identify the different entries (turn off/on) and use the links if necessary. It is probably wise to first take each list individually and extinguish it before moving on to the next. Then you can start over from 12v and leave the lists lit up as you go, to get a picture of the total inflow of signals.

Step 5.

Step 5. The LEFT and RIGHT vermiszoon together with the respective nucleus fastigii. Outflow and inflow of nerve signals. ALL IN ONE!! The nucleus fastigii and the vermis zone are already marked on both sides! The step includes forty-four (44) lists: 1v through 22v and 1h through 22h (v = left, h = right). The purpose of the step is that you should be able to build up the picture of the total outflow and inflow of nerve signals between the vermisdel of the spinocerebellum and the rest of the central nervous system (compare with the overview image in step 1). The easiest way is probably to start with the right side (lists 1h to 22h, see the headings!) and do the same as you did in Step 3 and Step 4 on the left side. Then light the lists 1v to 20v. You can then dissect the confusion that has then emerged by extinguishing and lighting in different combinations. You can also, with a slightly larger magnification, mouse click directly on the structure you are wondering about and thus get a name and instructions for the fact base. Do not forget to move around in the image and to vary the magnification. (Help) . NB! The identification function!
