Learning to Smell: Olfactory Perception from Neurobiology to Behavior
Learning to Smell: Olfactory Perception from Neurobiology to Behavior Books
Product Description
Written by a neurobiologist and a psychologist, this volume presents a new theory of olfactory perception. Drawing on research in neuroscience, physiology, and ethology, Donald A. Wilson and Richard J. Stevenson address the fundamental question of how we navigate through a world of chemical encounters and provide a compelling alternative to the “reception-centric” view of olfaction.
The major research challenge in olfaction is determining how the brain discriminates one smell from another. Here, the authors hold that olfaction is generally not a simple physiochemical administer, but rather a plastic administer that is strongly tied to memory. They find the habitual approach — which involves identifying how particular features of a chemical spur are represented in the olfactory system — to be at odds with historical data and with a growing body of neurobiological and psychological evidence that places primary emphasis on synthetic processing and experiential factors.
Wilson and Stevenson propose that experience and cortical plasticity not only are vital for habitual associative olfactory memory but also play a critical, defining role in odor perception and that current views are insufficient to account for current and past data.
The book includes a broad comparative overview of the structure and function of olfactory systems, an exploration into the mechanisms of odor detection and olfactory perception, and a discussion of the implications of the authors’ theory. Learning to Smell will serve as an vital reference for workers within the field of chemical senses and those interested in sensory processing and perception.

LEARNING TO SMELL: OLFACTORY PERCEPTION FROM NEUROBIOLOGY TO BEHAVIOR is written by a neurobiologist and psychologist and provides a new theory of olfactory perception, making it a not compulsory pick for any college-level health library holding. The major research in the area lies in determining how the brain identifies and separates smells: chapters reviews research approaches and propose that experience and cortical plasticity combine to play a defining role in odor perception. A review of the physiology of olfactory systems and mechanics of detection enhances this brilliant discourse.

The largest felonies in sensory science have to do with equating (1) the corporal spur, or (2) early neural signals, with psychological perception. For instance, as long as a thought scientist confuses wavelength with color, he will have no tenable scientific understanding of color, and he will at best publish confusing research. Alternatively, if he thinks that he can know color based on the simple outputs of three cone photoreceptors, he will remain in the dark, so to converse in.
Perhaps it is not honest to accuse most olfactory scientists of the aforementioned felony. But, most of them, report has it that, have focused on the front end of system, attempting to know how chemicals are transduced into neural signals and represented in the olfactory system. If their explanation of odor detection and discrimination ends there, they’ve blown it.
The authors suggest that, historically, researchers have frequently attempted to determine how a chemical spur is represented in the olfactory system, without considering context and learning.
But, the authors note that this perspective is at odds with extensive neurobiological and psychological data, which exhibit the importance of perceptual learing (i.e., synthetic processing and experiential factors) as different to the structural features of the spur as critical for odor discrimination. In reviewing the evidence, the authors conclude that the initial odorant features are not consciously accessible, and that this extraction is at best a first necessary stage for later cortical synthetic processing. “Cortical synthetic coding reflects an experience-dependent administer that allows synthesis of novel co-occurring features, similar to processes used for visual object coding. Thus, we propose that experience and cortical plasticity are not only vital for habitual associative olfactory memory (e.g. dread conditioning, maze learning, and delayed-match-to-sample paradigms), but also play a critical, defining role in odor discrimination.”
So, this book is on target because it frees itself from the shackles of simple models of chemical pattern recognition.
I’m not an expert on olfaction. My appreciation of this book was greatly enhanced by reading a very excellent introductory chapter on olfaction. This chapter appeared in Wolfe et al (Sensation & Perception, 2005), and was authored primarily (I judge) by Rachel Herz. This chapter included many informative illustrations, and the textbook website at Sinauer included an brilliant section on sensory memory cues based on Herz’ research. (I wish this book had colorful illustrations).
The authors do a superb job of comparing olfaction and olfaction research to research on the other senses, in particular the visual sense. They note the many similarities among sensory systems, and use these similarities to inform their analyses and their research. Moreover, they integrate their understanding of learning, memory and pattern recognition into the theoretical approach.
The integrative nature of this book was certainly a plus. If you are a psychophysicist or cognitive scientist, then it is hard to disagree with the authors on the key points of their theory.
