Taste and Smell Sensations

This video tutorial covers the anatomy and physiology of olfaction (smell) and gustation (taste). It explains the olfactory and gustatory pathways, detailing how smell and taste are processed in the brain. The tutorial also discusses the interaction between smell, taste, emotion, and memory, highlighting the role of the limbic system and hypothalamus. Additionally, it describes the five basic taste sensations and the potential sixth taste, fat. The video aims to provide a comprehensive understanding of these sensory systems, emphasizing their importance in human perception and survival.
