Set up the scene Here you can see the brain and upper part of the spinal cord from behind. Center the image and arrange with the appropriate magnification (Help). Check off 1, 2 below In the picture !! The hemispheres are now gone, the cerebellum split and the two bright red thalamus halves are opaque and separated from each other by the mid-aligned bright blue 3rd ventricle. If the picture needs to be explained check 3 and click on the link here read through, check out, try to understand and then check off 3!!, or go directly on to 4. Check off 4 and thalamus nuclei of different colors become visible. Check off 5 and the cores will all turn grey. Bend in 6 and the reticular thalamus nucleus, turquoise with a red outline, becomes visible. The core will be highlighted in the next nine (1 to 9) steps!

Step 1.

Signaling in to/afference and out of/efference the intralaminar core area. This column of text repeats under Description in step 1 through step 8. Each of the eight core areas of the vision pile (steps 1 - 8; one area per step) is presented under three headings (I, II and III). see below In Figure I. The distribution of the nuclear area in the right and left hemispheres of the brain. II. Afference to the left core area. III. Efference from the right core area. Under II and III, the core of the site is numbered consecutively from 1... Lowercase letters a and b after the number indicate the name of the kernel and its location in the area, respectively the afferent (II) or efferent (III) signal flows of the nucleus. Note that the reticular thalamus nucleus (light blue) is already in place when you enter the step. In the lists under heading II, the reticular thalamus nucleus appears as one (or more) cell body(s) with protrusions into the thalamus nucleus to be slowed down. The cortico-thalamic axons emit, on the way into the target nucleus, activating lateral branches of the reticular thalamus nucleus. This activation is illustrated with a blue checkmark. Also note that the left side thalamus nuclei (of course) have the same efferent signal outflows as shown on the right side and vice versa. The division here is due to the fact that it is otherwise very easy to get tangled if afference and efference are illustrated on one and the same page of the figure. Don't forget to unfold the different lists. One way (there are many) to manage a list is to tick it, unfold it, tick "extinguish all", then from the bottom tick the list and finally tick off the list. Try different variants (Help).

Step 9.

All in one. Here you can combine core areas and their incoming and outgoing signal flows with each other as you wish.My suggestion is that you tick the different boxes in order from top to bottom. The end result gives, I think myself, a good picture of the thalamus' role as coordinator of the various parts of the cerebral cortex with the world around us. As in the previous steps, the signal inflows "lie" to the left. and the outflows t.hay.
