Step 1.

Examine the deeper parts of the brain from the outside inward. If you now work your way into the brain and peel / cut away the brain tissue down to the brain beam (corpus callosum), you enter the white matter surrounded by the 2 - 4 mm thick cerebral cortex (cortex cerebri). The white matter consists of an almost unimaginably large number of thin myelinated and unmyelinated nerve fibers that are tightly packed together and form different types of conduction pathways.

Step 2.

Locate the different main types of wiring paths. The nerve fibre masses form, among other things, different projection pathways which, via the so-called The corona radiata conveys signal traffic between the cerebral cortex and lower levels of the central nervous system as well as pathway systems that constitute transverse -commissural - connections between the bark areas of the two hemispheres of the brain and longitudinal - associative - connections between different bark areas within the same hemisphere.

Step 3.

Continued examination of the deeper parts of the brain. Explore the different structures in the order they are located, from top to bottom of the list, i.e. from top to bottom when it comes to the brain. Light and extinguish as you go! Then you are down at the end of the list and can start to go up and gradually light the structures again to get a little repetition. When you have finished exploring all the deep structures, you can choose, in the steps that follow, to devote yourself to more limited parts of the deep areas - it can be a little tricky to grasp the contexts directly from the long list.
