S1: Nissl-stained coronal section #125 through the Göttingen minipig brain. The cortex at this level is agranular and without major difference between layer III/V and thus depicted as prefrontal cortex.

S2: Nissl-stained coronal section #200 through the Göttingen minipig brain. The major part of the cortex at this level is agranular and without major difference between layer III/V and thus depicted as prefrontal cortex. Note, however, that parietal cortex is emerging laterally.

S3: Nissl-stained coronal section #375 through the Göttingen minipig brain. Laterally, the parietal cortex can be segregated into a dorsal and a ventral somatosensory part. Ventrally, the rostral olfactory bulb is visible, while the cortex mediodorsally gradually is changed from prefrontal to motor cortex.

S4: Nissl-stained coronal section #575 through the Göttingen minipig brain. The anterior cingulate cortex is emerging medially, while insula (emerging at section #400) likewise is visible for the first time. Note, also the olfactory bulb and its dorsomedial accessory part.

S5: Nissl-stained coronal section #700 through the Göttingen minipig brain. Note how the olfactory bulb attach to the remaining part of the telencephalon, and the AO thus is separated into a lateral and a medial part, where the latter dorsally continues as the tenia tecta, while the former dorsally is transformed into prepiriform cortex. Note, also the vertical trajectory of the cingulate bundle (clearly visible on the myelin stain (not displayed in this paper)) lying deep to the BA25 and medial prefrontal cortex.

S6: Nissl-stained coronal section #800 through the Göttingen minipig brain. The anterior part of the lateral ventricle and the genu of corpus callosum is emerging. Note also the well-developed insula and the transition from the ventral agranular insular cortex to the dorsal granular/dysgranular insular cortex.

S7: Nissl-stained coronal section #900 through the Göttingen minipig brain. The striatum and the anterior crus of the internal capsule is now visible as a prominent inner telencephalic structure. Note also the appearance of the occipital lobe dorsally.

S8: Nissl-stained coronal section #975 through the Göttingen minipig brain. The dorsoposterior anterior olfactory nucleus is gradually changed into the olfactory tubercle. Note also the gradual transformation of the anterior cingulate cortex into the dysgranular posterior cingulate cortex and the appearance of peristriate cortex.

S9: Nissl-stained coronal section #1050 through the Göttingen minipig brain. The motor cortex is gradually replaced by striate, peristriate and posterior cingulate cortex. Note also that septum emerge at this level.

S10: Nissl-stained coronal section #1125 through the Göttingen minipig brain. The posterior cingulate cortex is gradually replaced by granular retrosplenial cortex. Note how the the caudate, putamen and accumbens nucleus is segregated in the telencephalic core.

S11: Nissl-stained coronal section #1200 through the Göttingen minipig brain. The septum with its medial and lateral septal complex is well developed at this level.

S12: Nissl-stained coronal section #1275 through the Göttingen minipig brain. The precommissural fornix bundle is visible in the posterior septum. The bed nucleus of stria terminalis and the ventral pallidum are likewise seen on this section.

S13: Nissl-stained coronal section #1375 through the Göttingen minipig brain. The anterior commissure, the diagonal region, thalamus, hypothalamus and the interventricular foramen are visible at this level. Note also how the parietal lobe has dimished in size, as well as the triangular shape and dorsoposterior position of the claustrum. Globus pallidus can likewise be clearly segregated from the more cell-dense and small celled putamen.

S14: Nissl-stained coronal section #1450 through the Göttingen minipig brain. The nucleus of the lateral olfactory tract mark the beginning of the amygdala. Note how the parietal lobe gradually is replaced by the temporal lobe.

S15: Nissl-stained coronal section #1550 through the Göttingen minipig brain. The most anterior part of the dorsal hippocampal formation is visible close to the midline. The granular retrosplenial cortex is fully developed at this level.

S16: Nissl-stained coronal section #1625 through the Göttingen minipig brain. The last remnant of the claustrum is visible on this section, and the transition from insular to perirhinal cortex is gradually initiated.

S17: Nissl-stained coronal section #1700 through the Göttingen minipig brain. The splenium of the corpus callosum lying just dorsal to the fasciola cinereum is visible on this level. Note also the position of the posterior part of the lateral ventricle as it course ventrally into the subrhinal lobe.

S18: Nissl-stained coronal section #1775 through the Göttingen minipig brain. The retrosplenial sulcus marks a sharp transition between the granular retrosplenial cortex and the ventral located hippocampal formation.

S19: Nissl-stained coronal section #1875 through the Göttingen minipig brain. Note the segregation of the hippocampal formation. The posterior commisure is visible at this level although its midpoint is located at section #1825-#1850.

S20: Nissl-stained coronal section #1925 through the Göttingen minipig brain.

S21: Nissl-stained coronal section #2000 through the Göttingen minipig brain. Note the relation between the retrosplenial granular cortex and the hippocampal formation, and the position of the parasubiculum.

S22: Nissl-stained coronal section #2075 through the Göttingen minipig brain. Note how the rhinal fissure and the splenial sulcus divide the hemisphere into a ventral subrhinal and retrosplenial part, and a dorsal occipital and temporal lobe part.

S23: Nissl-stained coronal section #2150 through the Göttingen minipig brain. The sagittal sulcus separate the entorhinal cortex into a medial and lateral part.

S24: Nissl-stained coronal section #2225 through the Göttingen minipig brain.
