New 15 Part Brain Model I. Disassembling of the 15 Part Model II. Assembling the 15 Part Model 1. Remove the top of both LEFT and RIGHT cerebral hemispheres. (anterior and posterior guide pins on each side) 1. Fit the ventricles into the LEFT half of the diencephalon / brainstem. 2. Remove the corpus callosum. 2. Fit the RIGHT half of the diencephalon / brainstem around the RIGHT ventricle from below and align the guide pins. 3. Remove the inferior frontal lobe (guide pins) by pulling it anterior. 3. On the LEFT 4. Remove the cerebellum by pulling it posterior and slightly inferior (guide pins). a. Press the striatum and lentiform nuclei (red) into the internal capsule. 5. Gently spread the temporal lobes laterally to release the diencephalon, ventricles and brainstem. b. Attach the insula cover over the putamen (red) via the two guide pins. 6. Pull diencephalon, ventricles and brainstem anterior and free from temporal lobe. 3. On the RIGHT a. Attach the caudate (red) to the medial side of the internal capsule. 7. On the Right b. Attach the lentiform nuclei (red) to the lateral side of the internal a. Remove the insular cortex from the diencephalon. b. Remove the lentiform (red) nucleus. c. Cover the lentiform nuclei with the insula cover via the two guide pins. On the Left 4. Gently pull the temporal lobes apart and insert the assembled diencephalon, ventricles and brainstem between the temporal lobes from the front. (posterior horns of ventricles will be in occipital lobe) a. Remove the insular cortex from the diencephalons. 5. Attach the cerebellum to the brainstem from below by engaging the guide plugs. b. Laterally remove the striatum and lentiform nuclei (red). 6. Attach the frontal lobe to the diencephalon via the guide pin. c. Remove the caudate nucleus and internal capusule. 7. capsule. 8. Separate the left and right diencephalons to expose the ventricles. 7. Attach the corpus callosum (guide pin posterior) to the occipital lobe. 9. Carefully remove the ventricles from their position. 8. Put the model into the base of the skull. 9. Attach the superior parts of the cerebral hemispheres to the model. New 15 Part Brain Model 1.
