Previously, we reported that male Wistar rats release alarm pheromone from their perianal region, which aggravates stress-induced hyperthermia (SIH) in pheromone-recipient rats. The subsequent discovery that this pheromone could be trapped in water enabled us to expose recipients to the pheromone in their home cages. Despite its apparent influence on autonomic and behavioral functions, we still had no clear evidence as to whether the alarm pheromone was perceived by the main olfactory system… Expand
Alarm pheromone is detected by the vomeronasal organ in male rats.
TLDR
It is shown that the vomeronasal organ plays an important role in alarm pheromone effects in the modified open-field test and acoustic startle reflex test. Expand
Vomeronasal organ ablation elicits chemosensory dysfunction and abnormal behavior in mice
TLDR
The results indicate that chronic VNO dysfunction led to anxiety-like or submissive behavior in mice, and it is suggested that pheromone perception deficiency might enhance self-odor production in mice. Expand
Vomeronasal organ lesion disrupts social odor recognition, behaviors and fitness in golden hamsters.
TLDR
The data suggested that vomeronasal organ ablation disrupted the olfactory recognition of social chemosignals in males, and induced anxiety-like and aggressive behavior changes in females, however, a vomer on asal organ lesion did not affect the reproductive capacity and fitness of hamsters. Expand
The alarm pheromone in male rats as a unique anxiety model: Psychopharmacological evidence using anxiolytics
TLDR
The alarm pheromone-enhanced ASR was not affected by vehicle pretreatment but was dose-dependently attenuated by pretreatment with midazolam, phenelzine, propranolol, clonidine, and CP-154,526-although not buspirone, which may reflect some aspects of the predictive validity of the alarm pothole-induced anxiety in rats as an animal model of human anxiety. Expand
Neural correlates underlying naloxone-induced amelioration of sexual behavior deterioration due to an alarm pheromone
TLDR
It is hypothesized that the alarm pheromone deteriorated sexual behavior by activating the ventrolateral periaqueductal gray-nucleus paragigantocellularis cluster and suppressing the magnocellular part of the paraventricular nucleus of the hypothalamus (PVN) via the opioidergic pathway. Expand
Pretreatment with CP-154526 blocks the modifying effects of alarm pheromone on components of sexual behavior in male, but not in female, rats.
TLDR
The results indicate that the alarm pheromone modifies male, but not female, components of sexual behavior and that corticotropin-releasing factor participates in the effects. Expand
Enhancement of the acoustic startle reflex by an alarm pheromone in male rats
TLDR
The results indicate that the alarm pheromone enhances the ASR by increasing anxiety in recipient rats, suggesting that the primary effect of the alarms phersomone is to increase the anxiety level. Expand
2-Heptanone Increases the Firing Rate of the Basal Amygdala: Role of Anterior Olfactory Epithelial Organs
TLDR
The results indicate that the SO-VNO is not essential for the effect of 2-heptanone on the firing rate of basal amygdala neurons, and that this structure participates in the expression of fear and the participation of anterior olfactory epithelial organs. Expand
Naloxone blocks the deterioration of male sexual behavior induced by alarm pheromone in rats.
TLDR
It is concluded that the alarm pheromone activates the CRH system, which then activates the opioid system, to deteriorate male sexual behavior. Expand
c-Fos expression during the modulation of sexual behavior by an alarm pheromone
TLDR
It is proposed that the alarm pheromone modifies sexual behavior by inducing CRH release that indirectly activates the nucleus paragigantocellularis. Expand

Alarm pheromone that aggravates stress-induced hyperthermia is soluble in water.
TLDR
Water collected from the box containing the alarm pheromone was found to generate a reproduction of all of the responses seen in the animal that had been directly exposed to alarm peromone in the authors' previous studies, which suggest that the alarms phersomone is soluble in water. Expand
Alarm pheromone enhances stress-induced hyperthermia in rats
TLDR
It is suggested that an alarm pheromone enhances stress responses of conspecific animals both behaviorally and physiologically, and that these effects are mediated via activation of the accessory olfactory bulb. Expand
Modulatory role of testosterone in alarm pheromone release by male rats
TLDR
The results suggest that the alarm pheromone released from stressed male rats can be classified into at least two categories according to the androgen dependency of their production and/or release. Expand
Alarm pheromone increases defensive and risk assessment behaviors in male rats
TLDR
The comparison with previous results suggests that the alarm pheromone released from the perianal region of the male rat increases anxiety in recipients, rather than evoking a stereotyped autonomic response. Expand
Alarm pheromones with different functions are released from different regions of the body surface of male rats.
TLDR
The results suggest that the alarm pheromone released from the face modifies behavior and that from the anal area induces autonomic stress responses in recipients. Expand
Role of the vomeronasal organ and prolactin in the acceleration of puberty in female mice.
TLDR
It is concluded that marked similarities exist in both the receptor system and neuroendocrine mechanism of male pheromone action observed in prepubertal females and that seen in the adult. Expand
Mapping the neural circuit activated by alarm pheromone perception by c-Fos immunohistochemistry
TLDR
It is suggested that the perception of the alarm pheromone is related to stress-responsive brains structures, including the hypothalamus and brainstem, as well as to the amygdaloid nuclei. Expand
Neural basis of olfactory memory in the context of pregnancy block
TLDR
These studies show that changes in synaptic plasticity in the accessory olfactory bulb following mating are critical to recognition of the stud male's pheromones, hence preventing these from subsequently blocking pregnancy. Expand
Ultrasensitive pheromone detection by mammalian vomeronasal neurons
TLDR
This work uses a mouse VNO slice preparation to show that six putative pheromones evoke excitatory responses in single vomeronasal neurons, leading to action potential generation and elevated calcium entry, providing a basis for understanding chemical signals that regulate mammalian communication and sexual behaviour.

TLDR
The equivocal evidence claiming a vestigial or absent organ in humans is reviewed and based upon anatomical considerations, the sensory epithelium of Jacobson's organ is one of five possible sensory components within the nasal cavity. Expand
