Accessory chemosignaling mechanisms in primates

Article Abstract:

Accessory olfaction is defined as the chemoreceptive system that employs the vomeronasal complex (VNC) and its distinct central projections to the accessory olfactory bulb (AOB) and limbic/cortical systems. Both main and accessory chemoreception seem to require collaborative molecular devices to assist in odorant transfer and signal recognition, and the most adaptive-selective features of primate chemocommunication variously resemble those of other terrestrial mammals.

Olfactory evolution and behavioral ecology in primates

Article Abstract:

Primates are usually considered as visual mammals, and several comparative studies have emphasized the role of vision in primate neural and sociocognitive specialization. The role of olfactory systems is explored, using phylogenetic analysis of comparative volumetric data, in which the relative sizes of the main olfactory bulb (MOB) and accessory olfactory bulb (AOB) tend to show different evolutionary patterns in accordance with their different functions.

Perceptual considerations in the use of colored photographs and video stimuli to study nonhuman primate behavior

Article Abstract:

The variations in nonhuman primate color vision and the impact this has on manipulating color in photographic and video stimuli is discussed. It was seen that changes made based on human perceptual abilities may look very different or may be imperceptible to the animals involved, which calls into the question the suitability of using mediums adapted to meet human perceptual needs.
