In an attempt to establish the neural bases of social recognition, isolated neurons from the vomeronasal organ of female and male L. bellii, were studied during the potential breeding season. The physiological properties of these cells were determined, as well as their ability to respond to different types of chemosignals from... [Pg.362]

During the preparation of this review, a Nobel Lecture describing the latest advances about olfactory perception and existence of odorant receptor genes as well as the role of the vomeronasal organ in the detection of odorants has recently been published by R. Axel [285] and L.B. Buck [286] Nobel Prize winners in Physiology or Medicine 2004). [Pg.439]

For all these chemical compounds to function as signals, developed chemosensory systems must be available. Extensive olfactory and vomeronasal organ systems and several auxiliary chemosensory systems provide the elephant with an extraordinarily sensitive and fine-tuned chemosensory detection system. Not only does the physiology (especially hormone levels and their actions) of both sexes affect the release of substances, these factors also influence the reception of chemical signals (Schulte et al., 1997 Slade et al., 1997 Rasmussen Schulte, 1998). [Pg.54]

Are there human pheromones Fiftyyears ago, Peter Karlson (1918-2001) from the Max-Planck-Institute for Biochemistry in Munich and Martin Liischer (1917-1979) from the University of Bern introduced this concept for substances, which are sent out by an animal in order to achieve a change in behaviour or a physiological response in another animal of the same species. [5] Mammals pick up the pheromones in special receptors in the vomeronasal organ (VNO, Vomer - an unpaired facial bone in the skuU) [6] located in the nasal cavity. [7] The information is transmitted to the hypothalamus, which influences the endocrine system. Until a few years ago, it was believed that in adult men the vomeronasal organ is atrophied. Then an intact VNO was discovered in the proximity of the nasal cavity s partition wall (Septum nasi). [8, 9]... [Pg.47]

Information about sex, reproductive condition and social status is all coded in chemical messages secreted or excreted by members of various species (see contributions in the three previous publications in this series) In addition to their information content, chemicals released by animals also affect physiological responses, and the vomeronasal organ seems to be particularly involved in reception of these chemical signals (pheromones). Many pheromonal effects depend on an intact vomeronasal system (see Table 1) they do not occur or are much reduced if the vomeronasal system of the recipient animal is rendered non-functional. Indeed, the organ has been implicated in the control of reproduction, especially in the onset of sexual... [Pg.472]

The subject of the present work is the highly developed chemosensory system of the elephant this system includes both the primary olfactory and the vomeronasal organ (VNO) systems. In such an intelligent mammal, separation of the chemosensory responses from auditory, tactile, and visual responses is difficult. A chemosensory response by the elephant depends on reception of a chemical signal, but its expression may be modified by an intricate combination of other cues, visual, tactile, and auditory, and by the physiological state and experiences of the animal. [Pg.627]
