(See p 221; figs. 88, 94) Where would you look for the rodent equivalent of the primate inferotemporal cortex? 2.

Name one type of axon which is present in all of these named structures. Then try and name some axons which are not present in all of them. 3. What is the rhinal sulcus? 4. Why did early anatomists mistakenly consider the olfactory peduncle, in the human brain, the most rostral cranial nerve? (The olfactory nerve itself is made up of the axons of the primary sensory neurons of the olfactory epithelium, which course through the cribiform plate at the base of the skull to end in glomerular structures of the olfactory bulb, where they synapse on mitral cells.
