Decades of cognition research have shown that external stimuli spark neural patterns in particular regions of the brain. This has fostered a view of the brain as a space that we can map: here the brain responds to faces, there it perceives a sensation in your left hand. But it turns out that the sense of smell only recently attracting broader attention in neuroscience doesn't work this way. A. S. Barwich asks a deceptively simple question: What does the nose tell the brain, and how does the brain understand it?Barwich interviews experts in neuroscience, psychology, chemistry, and perfumery in an effort to understand the biological mechanics and myriad meanings of odors. She argues that it is time to stop recycling ideas based on the paradigm of vision for the olfactory system. Scents are often fickle and boundless in comparison with visual images, and they do not line up with well-defined neural regions. Although olfaction remains a puzzle, Barwich proposes that what we know suggests the brain acts not only like a map but also as a measuring device, one that senses and processes simple and complex odors.Accounting for the sense of smell upsets theories of perception philosophers have developed. In their place, Smellosophy articulates a new model for understanding how the brain represents sensory information.(https://www.hup.harvard.edu/catalog.php?isbn=9780674983694)

La 4e de couverture indique : "Chez beaucoup d'espèces animales, les stimuli chimio-sensoriels et les stimuli olfactifs en particulier, jouent un grand rôle dans le contrôle et la régulation des comportements fondamentaux : marquage du territoire, repérage et circulation dans l'espace, recherche de nourriture et comportements alimentaires, comportements sociaux et reconnaissance interindividuelle, comportements sexuels et reproducteurs, comportements d'évitement de toutes formes de danger. Aussi l'odorat des animaux constitue t'il un modèle d'étude pour de nombreuses disciplines scientifiques (génétique, neurobiologie, sciences cognitives, éthologie...). En outre, interface entre les organismes et leur milieu, le système olfactif s'avère particulièrement exposé aux changements climatiques et aux pollutions de toutes natures, contribuant de fait, à la vulnérabilité de certains écosystèmes. Balayant le large spectre du règne animal, l'objectif de cet ouvrage est d'éclairer dans chaque paragraphe, un aspect particulier du système olfactif (une histoire de...) à travers le prisme d'une espèce particulière (le nez de...) en référence à des études ad hoc, pour la plupart très récentes."

Suzel Balez fait la synthèse des connaissances et débats contemporains sur les relations entre lieux et odeurs, et propose des clefs pour la conception olfactive spatialisée. Elle offre une référence à ceux qui souhaitent penser les espaces de façon multisensorielle et un outil de réflexion sur ses pratiques à tout « odorisateur » qu’il soit artiste, metteur en scène ou commercial. Après un état des obstacles à la pensée des ambiances odorantes, l'auteure propose un concept interdisciplinaire, l’effet odorant, permettant la compréhension comme la conception des phénomènes odorants situés.Les bases d’une telle conception spatiolfactive sont alors explorées en prenant en compte les matériaux mis en œuvre et leurs positionnements, relativement à leurs surfaces d’échange avec l’air ambiant, ses trajets et ses compositions.Inscrite dans une pensée multisensorielle des lieux, ces réflexions renvoient aux bouleversements environnementaux et à la manière de les prendre en compte dans la conception spatiale.

The “bioelectronic nose”, the device which has a similar function to the human smell sensing system, can be realized by combining the olfactory cells or receptors with nanotechnology. In the last two decades, much has been learned about the smell sensing mechanism in biological systems. With knowledge about the biological olfactory system and the techniques for the expression of biological receptor proteins, we are able to utilize biological materials and systems to mimic the biological olfactory system. In addition to the advances in biological and biotechnological area, nanotechnology has progressed to a great degree. The bioelectronic nose is a good example of the integration of biotechnology and nanotechnology. This book describes basic biological sciences of the olfactory system, biotechnology for the production of olfactory biological elements, and nanotechnology for the development of various sensing devices. The purpose of this book is to provide the reader with a concept, basic sciences, fundamental technologies, applications, and perspectives of the bioelectronic nose.

This book discusses the field of bioinspired smell and taste sensors which includes many new areas: sensitive materials, physiological modelling and simulation, and more. Similar to biological chemical sensing systems, bioinspired smell and taste sensors are characterized with fast responsive, high specificity and sensitivity. One of the most important parts of the field is that of sensitive elements originated from biological components, which enable the detection of chemical signals by mimicking the biological mechanisms. This book detailed describes processing, devices, recognition principles of sensitive materials, and concrete realizations. It is written for researchers, engineers and biologists who engages in interdisciplinary research and applications. Dr. Ping Wang is a professor at Zhejiang University, Hangzhou, China. Dr. Qingjun Liu is a professor at Zhejiang University, Hangzhou, China. Dr. Chunsheng Wu is an associated professor at Zhejiang University, Hangzhou, China. Dr. K. Jimmy Hsia is a professor at University of Illinois at Urbana-Champaign, Urbana, USA.
