Brain, advanced and transparent anatomical model with internal structures in 15 parts

Anatomically, the model shows the human brain, which can generally be divided into the cerebrum (cerebrum), the cerebellum (cerebellum) and the brain stem (truncus encephali).



These 3 structures are seen in very different ways. A large part of the cerebrum is seen in transparent material without anatomical details, but on the other side the superior sagittal sinus is visible. The cerebellum and brainstem are shown in different color tones and with numerous anatomical details. The difference between gray and white matter is only seen in the cerebellum.



The pictures on the left show how the model can be separated into 15 parts. All significant internal structures are seen via different shape and color. Furthermore, most are seen in 3 dimensions. For example, the amydala is illustrated particularly clearly in its "almond shape", while both the cerebellum and the brainstem can be taken out and divided into 2.



As previously mentioned, the cervical spine is seen as part of the stand. You see the bone tissue in transparent material, while soft parts such as discs (the ligament discs) and spinal nerves are seen in a beige or whitish shade. Furthermore, the vertebral artery is seen on each side.





The limbic system



Many of our customers ask about the limbic system in connection with the purchase of brain models. Hence this description.



The limbic system includes various anatomical structures in the central nervous system (CNS), and is primarily responsible for emotional functions such as anxiety, aggressiveness, mood, memory and social adaptability. Clinically, it is therefore often related to psychiatric disorders.



The limbic system includes, among other things amygdala, hippocampus, gyrus parahippocampalis, hypothalamus, fornix, corpus mammillare, the prefrontal cerebral cortex and the monoaminergic systems of the brainstem. The list is quite a bit longer - especially because numerous fiber connections connect the limbic structures. Many customers ask in particular about the amygdala and hippocampus (which is why they are mentioned first in this section).



NB: This brain model is the only one in our range that shows a physical representation of the amygdala. In addition, the hippocampus and other limbic structures are seen.



The amygdala is involved in anxiety and emotional coloring of sensory impressions. It lies as an almond-shaped nucleus IN FRONT of the hippocampus in the anterior pole of the temporal lobe (amygdala and hippocampus are therefore separate).



The hippocampus is involved in memory. It lies as an irregular twisted structure in the medial part of the temporal lobe.

If one of these 2 structures is to be seen clearly on a brain model, the brain tissue must be shown in a so-called frontal/coronal section through the temporal lobe. The frontal incision roughly corresponds to the incision direction "from ear to ear".



Because the amygdala is IN FRONT of the hippocampus (roughly speaking further "toward the forehead"), both of these structures can only be seen on a brain model if the model includes at least 2 frontal sections through the temporal lobe - or if the brain model is partially transparent like this one.



It should be added that we have not yet seen a brain model that is not partially transparent and at the same time shows 2 cuts through the temporal lobe, so that both the amygdala and the hippocampus are seen.



All brain models in our range can be separated into different parts. All models (both with and without educational colors) that can be separated into 4 or more parts show the hippocampus. On almost all of these models, the hippocampus is also numbered and named on an overview that can be downloaded from the product descriptions of the brain models.
