The vomeronasal organ of the tammar wallaby [PDF]

Journal of Anatomy, 2008
AbstractThe vomeronasal organ is the primary olfactory organ that detects sexual pheromones in mammals. We investigated the anatomy of the vomeronasal organ of the tammar wallaby (Macropus eugenii), a small macropodid marsupial. Pheromones may be important for activation of the hypothalamo‐pituitary axis of tammar males at the start of the breeding ...

Disparity of turbinal bones in placental mammals

The Anatomical Record, Volume 309, Issue 4, Page 749-777, April 2026.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Prenatal growth of the human vomeronasal organ [PDF]

The Anatomical Record, 1997
Vomeronasal organs (VNOs) are paired epithelial structures located adjacent to the nasal septum that form in the late first trimester of human fetal development. Although VNOs have long been known to exist in fetal and adult humans, some studies continue to suggest that these structures may be degenerative or functionless. Little is known of the growth

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

The Anatomical Record, Volume 309, Issue 4, Page 826-852, April 2026.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

The Anatomical Record, Volume 309, Issue 4, Page 1037-1060, April 2026.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Exploring Larval Axolotl Brain Development: Insights Into Developmental and Functional Constraints

Evolution &Development, Volume 28, Issue 1, March 2026.
We studied brain shape and volume variations during larval development of the Mexican axolotl. Modularity, morphological integration, and allometric regressions supported both mosaic and concerted evolution models, highlighting a complex interplay of constraints during axolotl ontogeny.

Comparison of sexual behaviours and libido changes in septorhinoplasty patients with vomeronasal organ dissection by gender: A clinical study

Medicine Science
Animals use the vomeronasal organ for interactions, including sexual intercourse, with conspecifics. Whether this orientation exists in humans is not yet fully understood.

Functional Overexpression of Vomeronasal Receptors Using a Herpes Simplex Virus Type 1 (HSV-1)-Derived Amplicon.

PLoS ONE, 2016
In mice, social behaviors such as mating and aggression are mediated by pheromones and related chemosignals. The vomeronasal organ (VNO) detects olfactory information from other individuals by sensory neurons tuned to respond to specific chemical cues ...

Vomeronasal Organ: Pheromone Recognition with a Twist [PDF]

Current Biology, 2003
Pheromones are detected by the vomeronasal organ using members of two receptor superfamilies: the V1Rs and V2Rs. New studies show that MHC class I molecules are co-expressed in particular combinations with specific V2Rs in the vomeronasal organ. The role of these MHC molecules is unknown, but they may be of considerable biological significance.

Foxg1 Defines Ventrolateral Zonal Identity by Sustaining Neurogenic Progenitor Potential in the Olfactory Epithelium

Genes to Cells, Volume 31, Issue 2, March 2026.
Foxg1 maintains neurogenic progenitor potential in the ventrolateral olfactory epithelium. In control (Foxg1‐cHET) embryos, Foxg1‐expressing progenitors preferentially generate olfactory sensory neurons (OSNs) and support V‐zone expansion. Conditional Foxg1 deletion (Foxg1‐cKO) reduces V‐zone growth and shifts progenitor fate toward sustentacular cells
