Explore the intricate mechanisms behind movement sequences in the nervous system through this 48-minute lecture by Andrew Seeds from the Institute for Neurobiology at the University of Puerto Rico. Delve into the fascinating world of grooming behaviors in dusty flies, examining neural activation patterns and the concept of hierarchical suppression. Investigate the sensory neurons responsible for specific grooming movements, with a focus on mechanosensory systems in Drosophila. Uncover the role of Johnston's Organ neurons in antennal grooming and learn about the reconstruction of neural circuits using electron microscopy. Analyze the organization of head grooming circuits and explore hypotheses regarding neurons involved in grooming behaviors. Gain valuable insights into the complex interplay between sensory input, neural circuitry, and motor output in the production of coordinated movement sequences.
