Question from last class What produces the chloride gradient across OSN cilia? Is there more chloride inside the cell or less outside the cell compared to “normal” conditions?

Olfaction, memory, and emotion Olfaction is unique among the senses for its direct and intimate connection to the limbic system (involved in emotion, motivation, reward, and long-term memory) Explains why scents tend to have such strong emotional associations Key to olfactory associative learning is the experiences when the odors were encountered and emotional connotations of those experiences Examples from class?

Olfaction, memory, and emotion Are odors really the best cues to memory? Other modalities can elicit memory just as well (i.e. - vision, touch, taste) Memories triggered by odor cues are distinctive in their emotionality Emotion and evocativeness of odor-elicited memories lead to false impression that such memories are especially accurate

Olfaction, memory, and emotion Aromatherapy – contends that odors can influence and alter mood, performance, well-being and physiological correlates of emotion, such as heart rate, blood pressure and sleep Do you think this is scientifically accurate? Certain odors can elicit various beneficial behavioural, emotional, and physical effects, but only if the aroma in question has been previously associated with a corresponding positive emotional experience

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
