Step | Modified dissection procedure | Exposed tracts |
---|---|---|
1 | Removal of the olfactory bulb cortex | Stem of olfactory tract Olfactory-basal forebrain connections |
2 | Removal of cortex on rostral part of the temporal and parahippocampal gyri | Olfactory-parahippocampal tract |
3 | Removal of cortex on the frontal lobe | Lateral olfactory frontal connections |
4 | Removal of short association fibers of temporal and occipital lobes | Olfactory-parahippocampal tract Olfactory-occipital tract |
5 | Removal of the superior longitudinal fasciculus, the uncinate fasciculus, and the lenticular nucleus | Fronto-occipital fasciculus |
6 | Removal of olfactory-occipital tract and fronto-occipital fasciculus and opening of the temporal horn of the lateral ventricle | Ventral cingulum Body and column of fornix |
7 | Removal of fornix, olfactory-parahippocampal tract, and olfactory-basal forebrain connections | Rostral commissure Olfactory-spinal tract |
8 | On the other hemisphere, removal of basal surface olfactory bulb cortex | Olfactory-basal forebrain connections |
9 | Removal of parahippocampal gyrus cortex | Olfactory-parahippocampal tract |
10 | Removal of anterior perforated substance | Medial and lateral olfactory tracts Rostral commissure |
12 | Removal of rostral commissure, accumbens nucleus and thalamus | Olfactory-spinal tract |
13 | Opening the rostral horn and body of the lateral ventricles on both hemispheres | Fornix |
14 | Removal of fornix and caudate nucleus | Olfactory-stria terminalis tract |
