Cori Bargmann (Rockefeller) Part 2: Cracking the circuits for olfaction

http://www.ibioseminars.orgIn her first talk, Cori Bargmann explains how individual genes can affect the brain and behavior. Humans are complex creatures, but as many as 99% of our genes are shared with simpler organisms. By focusing on the genes for a family of proteins found in many organisms, the G protein-coupled receptors, Bargmann illustrates that mutations in a single gene can cause significant behavioral changes in organisms as diverse as nematodes, dogs and humans. In Part 2, Bargmann presents work from her own lab in which the olfactory system in C. elegans was used to dissect the role of genes on behavior. She shows us how it was possible to map the neuronal circuits that modulate worm behavior in response to different odors.
