Mammalian pheromones control a myriad of innate social behaviors and acutely regulate
hormone levels. Responses to pheromones are highly robust, reproducible, and stereotyped …

TAAR1 is widely expressed across the mammalian brain, particularly in limbic and
monoaminergic areas, allegedly involved in mood, attention, memory, fear, and addiction …

Sensory cues that predict reward or punishment are fundamental drivers of animal behavior.
For example, attractive odors of palatable food or a potential mate predict reward, while …

The pseudostratified olfactory epithelium (OE) may histologically appear relatively simple,
but the cytological relations among its cell types, especially those between olfactory receptor …

Many species are critically dependent on olfaction for survival. In the main olfactory system
of mammals, odours are detected by sensory neurons that express a large repertoire of …

The existence of innate predator aversion evoked by predator-derived chemostimuli called
kairomones offers a strong selective advantage for potential prey animals. However, it is …

The mechanisms by which odors induce instinctive behaviors are largely unknown. Odor
