70527 | Infralimbic area | Piriform area | moderate/strong | PHAL | The piriform cortex received innervation via both the lateral and ventral pathways (see Fig. 3A-D). Labelled fibers were observed throughout the rostral piriform cortex. primarily in the molecular and polymorph layers. Fibers in the molecular layer demonstrated varicosities along their lengths, whereas labelled fibers in the polymorph layers only occasionally exhibited swellings. At rostral levels, the dorsolateral portion of the piriform cortex demonstrated a slightly heavier innervation as compared to other parts of the piriform cortex. These fibers apparently arose from the lateral efferent pathway. By the level of the septum and proceeding further caudally, the density of innervation in the piriform cortex began to shift ventrally and arose primarily from the ventral efferent pathway. The majority of labelled fibers formed a dense plexus within the molecular layer. Some labelled fibers pierced the pyramidal layer perpendicular to the pial surface and entered the polymorph cell layer. Collator note: molecular layer, considered as a separate record. | Hurley KM, Herbert H, Moga MM, Saper CB., 1991 | |

General description technique/protocol: Collator note: Case R651, the injection covers ILA (ILC as in this reference and the dorsal peduncular cortex) with small extension in the ventral prelimbic cortex, the medial orbital cortex rostrally, and ventrally possible spill in the dorsal part of the TT. The injection is shown in Figure 1B and it was mapped by us on Levels 9-10, Swanson-2004 Atlas. |
