From sexual attraction to maternal aggression: When pheromones change their behavioural significance [PDF]

open access: yes, 2015
This article is part of a Special Issue “Chemosignals and Reproduction”. This paper reviews the role of chemosignals in the socio-sexual interactions of female mice, and reports two experiments testing the role of pup-derived chemosignals and the male

EVOLUTION OF VOMERONASAL ORGANS IN VERTEBRATES [PDF]

open access: yesEvolution, 1981
The vomeronasal (VN) (Jacobson's) organs are paired chemosensory organs located in the vertebrate nose. They generally are formed only in tetrapods (Negus, 1958). Accessory olfactory bulbs and nerves that may innervate rudimentary VN organs have been described in the African lungfish Protopterus (Rudebeck, 1944) and the paddle fish Polyodon (Story ...

In-vivo Vomeronasal Stimulation Reveals Sensory Encoding of Conspecific and Allospecific Cues by the Mouse Accessory Olfactory Bulb [PDF]

open access: yes, 2012
The rodent vomeronasal system plays a critical role in mediating pheromone-evoked social and sexual behaviors. Recent studies of the anatomical and molecular architecture of the vomeronasal organ (VNO) and of its synaptic target, the accessory olfactory ...

Prevalence, persistence and microscopic aspects of the vomeronasal organ in normal versus embryos with chromosomal abnormalities

open access: yesJournal of Mind and Medical Sciences
Background. The objective of this study was to describe the histological and immunohistochemical aspects of vomeronasal organ in two groups of (normal and pathological) embryos and fetuses, with chromosomal morphological abnormalities. Methods.

Anatomy, histochemistry and immunohistochemistry of the olfactory subsystems in mice

open access: yesFrontiers in Neuroanatomy, 2014
The four regions of the murine nasal cavity featuring olfactory neurons were studied anatomically and by labelling with lectins and relevant antibodies with a view to establishing criteria for the identification of olfactory subsystems that are readily ...

Evolutionary patterns and selective pressures of odorant/pheromone receptor gene families in teleost fishes. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: Teleost fishes do not have a vomeronasal organ (VNO), and their vomeronasal receptors (V1Rs, V2Rs) are expressed in the main olfactory epithelium (MOE), as are odorant receptors (ORs) and trace amine-associated receptors (TAARs).

Regeneration of New Neurons is Preserved in Aged Vomeronasal Epithelia [PDF]

open access: yes, 2010
During normal and diseased aging, it is thought the capacity for tissue regeneration and repair in neuronal tissues diminishes. In the peripheral olfactory system, stem cell reservoirs permit regeneration of olfactory and vomeronasal sensory neurons, a ...

Presynaptic GABAB receptors inhibit vomeronasal nerve transmission to accessory olfactory bulb mitral cells

open access: yesFrontiers in Cellular Neuroscience, 2023
Vomeronasal sensory neurons (VSNs) recognize pheromonal and kairomonal semiochemicals in the lumen of the vomeronasal organ. VSNs send their axons along the vomeronasal nerve (VN) into multiple glomeruli of the accessory olfactory bulb (AOB) and form ...

Tracing Early Migratory Neurons in the Developing Nose Using Contactin-2 (Cntn2) CreERT2. [PDF]

open access: yesGenesis
ABSTRACT Neuronal migration during embryonic development is a fundamental process. In the developing nose of rodents, neurons that form during early neurogenic waves in the olfactory placode leave this structure to migrate toward or into the developing brain as part of the migratory mass.

A transcriptomic reevaluation of the accessory olfactory organ in Bichir (Polypterus senegalus)

open access: yesZoological Letters, 2022
Fish possess one olfactory organ called the olfactory epithelium (OE), by which various chemical substances are detected. On the other hand, tetrapods possess two independent olfactory organs called the main olfactory epithelium (MOE) and vomeronasal ...
