Set up the stage! The picture shows the central nervous system as seen from behind. Hay-click in the image and "zoom out" to the right size. Center using the arrow cross! Then follow the instructions below OR go directly to step 1 where the scene is set up. Deselect 1/and2/. Compare with the initial steps in the picture "Central Nervous System Nuclei"! Uncheck a) empty d) if you think they are disturbing. Deselect 3/and4/. If necessary, unfold the list 5/ and repeat the thalamus nuclei; otherwise uncheck 5/. Tick and fold out in turn Rafe nuclei and Serotonin-producing cell groups. Identify the members of each group. The stage is now set up. NB! Place and move the image around the way you want it on the screen, use different magnifications, and go through lists (Help).

Step 1.

Step 1. Inflows and outflows of nerve signals to and from serotonin-producing cell groups. Here, the western half shows areas that send nerve signals into serotonin-producing cell groups in the larger nuclei. The hay.cns half shows areas that receive nerve signals from serotonin-producing cell groups in larger nuclei. Start by ticking 1/w. Then tick 2/,3/ and 4/ in turn so that each list first lights up, then unfolds, goes through and finally folds and turns off before the next list is activated. When all three lists have been reviewed separately, it is time to have them all lit at the same time and be surprised by the massive influx of signals from the environment into the serotonin producers. Turn off 1/empty 4/ on the left. page! Then activate in turn 1/ to 9/ on the right page. Here, there is less risk of it getting bogged down if you leave everyone open and lit at the same time. But a good piece of advice is probably to first deal with the outflow from the rostral core group and then extinguish it before addressing the caudal group. Then light everything both to hay. and we. to get an idea of the widespread distribution and astonishing complexity of the serotonin-producing system. NB! Place and move the image around the way you want it on the screen and use different magnifications (Help) .
