Resumen:
Introduction: The olfactory system in most mammals is divided into
several subsystems based on the anatomical locations of the
neuroreceptor cells involved and the receptor families that are
expressed. In addition to the main olfactory system and the vomeronasal
system, a range of olfactory subsystems converge onto the transition
zone located between the main olfactory bulb (MOB) and the accessory
olfactory bulb (AOB), which has been termed the olfactory limbus (OL).
The OL contains specialized glomeruli that receive noncanonical sensory
afferences and which interact with the MOB and AOB. Little is known
regarding the olfactory subsystems of mammals other than laboratory
rodents.Methods: We have focused on characterizing the OL in the red fox
by performing general and specific histological stainings on serial
sections, using both single and double immunohistochemical and
lectin-histochemical labeling techniques.Results: As a result, we have
been able to determine that the OL of the red fox (Vulpes vulpes)
displays an uncommonly high degree of development and
complexity.Discussion: This makes this species a novel mammalian model,
the study of which could improve our understanding of the noncanonical
pathways involved in the processing of chemosensory cues.
