Rodent alarm chemosignals elicit various behavioral and physiological responses in conspecifics. This study employed a bioassay method, using a modification of the forced swim test, to demonstrate that the pituitary mediates production and/or secretion of an alarm chemosignal in rats subjected to stress. This was shown by comparing the immobility times of rats in water soiled by hypophysectomized and sham-treated rats. Rats tested in water soiled by sham-treated rats exhibited very little… Expand

Modulatory role of testosterone in alarm pheromone release by male rats
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
The role of neuroinflammation in the release of aversive odor cues from footshock-stressed rats: Implications for the neural mechanism of alarm pheromone
It is demonstrated that stressed rats release odorant cues that cause other rats to move away from the source of the signal, mediated by inflammatory cytokine responses in the brain. Expand
Alarm pheromones with different functions are released from different regions of the body surface of male rats.
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
The effects of calorie restriction olfactory cues on conspecific anxiety-like behaviour
Olfactory cues from conspecifics on a CR regime significantly reduced anxiety- like behaviour in rats fed ad libitum, similar to the reduction in anxiety-like behaviour following CR. Expand

It is concluded that social cues for facilitating social approach are eliminated via the 5-HT → OT pathway, and BALB mice as a low social strain have a deficit in recognition of specific signals associated with amicability. Expand

The processing of human social chemosignals resembles the processing of social signals originating from other modalities, except that human social chemicals are usually communicated without the allocation of attentional resources, that is below the threshold of consciousness. Expand
Pheromones, Odors, and Vasanas
Publisher Summary Social chemosignals are not simply vestigial. Rather, they are the oldest sensory system for coordinating social and reproductive behavior. Because they are evolutionarilyExpand
Chemosensory anxiety signals augment the startle reflex in humans
It is concluded that chemosensory anxiety signals may pre-attentively prime defensive behavior and activate behavioral withdrawal systems in humans. Expand
Peripheral Effects of Melanocortins
In this chapter, aspects of melanocortin function other than melanogenesis and steroidogenesis that appear to be at least partially a result of interaction with peripheral melancortin receptors are discussed. Expand
Exocrine Gland Dysfunction in MC5-R-Deficient Mice: Evidence for Coordinated Regulation of Exocrine Gland Function by Melanocortin Peptides
Data show a requirement for the MC5-R in multiple exocrine glands for the production of numerous products, indicative of a coordinated system for regulation of exocrine gland function by melanocortin peptides. Expand
