Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Explain in what way smell and taste stimuli differ from other sensory stimuliIdentify the five primary tastes that can be distinguished by humansExplain in anatomical terms why a dog’s sense of smell is more acute than a human’s

By Linda Bartoshuk and Derek Snyder, University of Florida. Humans are omnivores (able to survive on many different foods). The omnivore’s dilemma is to identify foods that are healthy and avoid poisons. Taste and smell cooperate to solve this dilemma. Stimuli for both taste and smell are chemicals. Smell results from a biological system that essentially permits the brain to store rough sketches of the chemical structures of odor stimuli in the environment. Thus, people in very different parts of the world can learn to like odors (paired with calories) or dislike odors (paired with nausea) that they encounter in their worlds. Taste information is preselected (by the nature of the receptors) to be relevant to nutrition. No learning is required; we are born loving sweet and hating bitter. Taste inhibits a variety of other systems in the brain. Taste damage releases that inhibition, thus intensifying sensations...

Culture, Embodiment, and the Senses will provide an historical and cross-cultural analysis of the politics of sensory experience. The subject will address western philosophical debates about mind, brain, emotion, and the body and the historical value placed upon sight, reason, and rationality, versus smell, taste, and touch as acceptable modes of knowing and knowledge production. We will assess cultural traditions that challenge scientific interpretations of experience arising from western philosophical and physiological models. The class will examine how sensory experience lies beyond the realm of individual physiological or psychological responses and occurs within a culturally elaborated field of social relations. Finally, we will debate how discourse about the senses is a product of particular modes of knowledge production that are themselves contested fields of power relations.

An integrated course stressing the principles of biology. Life processes are examined primarily at the organismal and population levels. Intended for students majoring in biology or for non-majors who wish to take advanced biology courses.

"This course provides an introduction to important philosophical questions about the mind, specifically those that are intimately connected with contemporary psychology and neuroscience. Are our concepts innate, or are they acquired by experience? (And what does it even mean to call a concept 'innate'?) Are 'mental images' pictures in the head? Is color in the mind or in the world? Is the mind nothing more than the brain? Can there be a science of consciousness? The course will include guest lectures by Professors."

Olfaction is another word for the sense of smell. In this video, I summarize the process of olfaction beginning with the olfactory receptors found in the olfactory epithelium. I follow the path of olfactory information until it reaches the olfactory cortex, where most olfactory processing in the brain occurs.

Taste (gustation), smell (olfaction), and touch sensory and perceptual processes. Vestibular sense, proprioception, and kinesthesia are also briefly introduced. Duration: 2:39.
