Comparative genomic analysis identifies an evolutionary shift of
vomeronasal receptor gene repertoires in the vertebrate transition from water to land.
Organization of
vomeronasal sensory coding revealed by fast volumetric calcium imaging.
Sometimes a foamy discharge is produced in an attempt to dissolve some of these chemical signals and push them through the oral duct into the
vomeronasal organ for analysis.
The
vomeronasal organ (VNO) is an essential functioning organ in some animals.
Ejemplos de estos sistemas los encontramos en las reacciones aversivas de mamiferos como los felinos a traves del mecanismo piloerector, la conducta de apareamiento de las aves o las senales de feromonas captadas a traves del organo
vomeronasal presente en roedores.
They found that mice who lack a critical gene in the pheromone-detecting region of the nose, called the
vomeronasal organ (VNO), were able to locate the mother's nipple and to suckle.
Using a behavior called flehmen, or lip curl, some of the urine is introduced into a specialized organ on the roof of the mouth called the
vomeronasal organ, where it is analyzed.
Using a behavior called flehmen, or hp curl, some of the urine is introduced into a specialized organ on the roof of the mouth called the
vomeronasal organ, where it is analyzed.
Size of the
vomeronasal organ in wild microtus with different mating strategies.
Specifically, in rodents, reproductively relevant pheromonal cues are detected by receptors in the
vomeronasal organ, which in turn transmit this information centrally via the accessory olfactory bulb, the medial nucleus of the amygdala, the posterior medial bed nucleus of the stria terminalis and the medial preoptic area.
Recent study has shown that Bcl11b is also expressed in the developing
vomeronasal system in the accessory olfactory bulb of the mouse as well.
La olfatoria forma el epitelio olfatorio de la nariz y los axones de las neuronas sensoriales, que se proyectan al bulbo olfatorio, organo
vomeronasal y nervios terminales; ademas, forma las celulas gliales, que ingresan y migran hacia el cerebro (17,18,20).
