WebThe medial olfactory stria medially passes along the rostral boundary of the anterior perforated substance, nearing the medial continuation of the diagonal band of Broca. Together, these curve upwards on the medial hemisphere aspect. This is anterior to the attachment of the lamina terminalis. WebThe olfactory tract connects the olfactory bulb to the remainder of the cerebral cortex. This creates a direct connection between the sensory output from the olfactory neurons and the olfactory cortex (Mancall & Brock, 2011 ). This pathway is unique to the olfactory pathway in that the sensory input bypasses the thalamus ( Mancall & Brock, 2011 ). gerhart calibrationWebThe AON is found behind the olfactory bulband in front of the piriform cortex(laterally) and olfactory tubercle(medially) in a region known as the olfactory peduncle[3]or retrobulbar area. The peduncle contains the AON as well as two other much smaller regions, the taenia tecta(or dorsal hippocampal rudiment) and the dorsal peduncular cortex. christine cook
