MCB 125. Molecular Basis of Behavior
Catalog Number: 159655  View Course Website
Term: Spring 2016-2017.
Instructor: Catherine Dulac
Course Level: For Undergraduates and Graduates
Description: Modern molecular genetic approaches are teaching us a great deal on how the brain controls behaviors. This course will cover newly developed experimental strategies of molecular neuroscience, and how they have helped uncover the nature and identity of behavior circuit components. How genes and molecules affect behaviors will be investigated through key examples of mammalian behaviors with an emphasis on instinctive and social behaviors, their expression, development, and associated mental disorders.

Description: "The great art of life is sensation, to feel that we exist, even in pain." Lord Byron. Molecular basis of normal and pathological sensory perception, formation and modulation of sensory circuits during development and in the adult brain. Topics will include the mechanisms of sensory detection and discrimination, the discovery of key genes, cellular pathways and neural circuits affected in human disorders, molecular and genetic strategies for restoring normal sensation, coding of sensory information by the brain, establishment of appropriate connections in the developing brain, epigenetic influences on sensory function. Molecular, genetic and epigenetic approaches to normal and pathological sensing and associated behavior will be discussed.

Our group is using molecular, genetic and electrophysiological techniques to explore the molecular and neuronal basis of innate social behaviors in the mouse. Two major lines of research are currently being pursued in the laboratory:

We are pursuing several projects at the molecular, cellular and systems levels in order to investigate the architecture and functional logic of neuronal circuits underlying pheromone signaling. The key questions we are addressing are: What is the nature of the mammalian pheromones and of the receptors that detect them? How are pheromone signals processed in the brain in order to generate species- and sex-specific behaviors such as aggression, mating, parental behavior, defensive behavior? What are the basic developmental processes that ensure appropriate neuronal connections between the olfactory sensory neurons and the brain? What are the respective roles of sensory experience and genetic information in setting appropriate pheromone-induced behaviors, and how are circuits underlying sex-specific behaviors established in the male and female brains?

The second set of projects explores the phenomenon of genomic imprinting in the brain, and the role of this mode of epigenetic modification in brain development and adult brain function. Genomic imprinting results in preferential expression of the paternally, or the maternally inherited allele of certain genes. We have recently used a genome-wide approach to characterize the repertoire of imprinted genes in the mouse embryonic and adult CNS. Our study uncovered over 1000 new loci with imprinted features, suggesting that imprinting is a major mode of epigenetic regulation in the brain. Imprinting appears to preferentially affect neural systems associated with social, motivational and homeostatic brain functions. Comparison of the imprinted gene repertoire in the adult hypothalamus and cortex, and in the developing brain demonstrates a complex spatiotemporal, species-, sex- and isoform-specific regulation. Genomic imprinting thus emerges as a major and dynamic mode of epigenetic regulation of brain function, with direct implications for the understanding of evolution and diseases. Future projects in the lab will aim at better understanding this mode of epigenetic regulation in mechanistic and functional terms.
