​Animal behavior is mediated by the nervous system, according to information encoded in the genome. The Ben-Shahar lab uses a variety of behavioral, genetic, genomic, biochemical, and molecular techniques to decipher the genetic architecture that drives specific behaviors.

The Ben-Shahar lab uses a variety of behavioral, genetic, genomic, biochemical, and molecular techniques to decipher the genetic architecture that drives specific behaviors. We use the powerful model of the fruit fly, Drosophila melanogaster to understand how the function of specific genes in distinct neuronal circuits gives rise to behaviors such as feeding and mating. We are also interested in taking advantage of the recent sequencing of 12 genomes of species from the Drosophila genus, which now allow us to ask questions about the evolution of behavior.

Currently the lab is focusing on several projects:

  • The role of ligand-gated ion channels as neuronal modulators and sensory transducers
  • The role of neuropeptides and their receptors in modulating behavior
  • The role of divalent cation transporters in feeding induction and food selection
  • The evolution of behaviorally-related genomic modules in the genus Drosophila

 

recent courses

Genes, Brains, and Behavior (Biology 3422)

Genetic studies of physiological systems underlying animal behavior, including the genetic basis for normal and abnormal behaviors in animals and humans. Topics include: history of behavioral genetics; the ongoing debate about “nature vs. nurture”; contributions of genetic model systems including the nematode Caenorhabditis elegans, the fruit fly Drosophila melanogaster, zebrafish, the mouse Mus musculus, and other animal models; molecular mechanisms underlying the evolution of behavioral phenotypes; the emerging role of epigenetics in regulating nervous-system functions and behavior; the use of genetic and genomic analyses in studies of human behavior and psychiatric disorders.

    First-Year Seminar in Imaging Sciences (Biology 1810)

    An introduction to the breadth and depth of imaging sciences across Arts & Sciences, Medicine and Engineering, on topics from radiology to cell biology. Seminars are presented by experts in these fields to acquaint undergraduate students with advances in imaging sciences and research opportunities in these areas. This seminar is the preferred entry point for freshmen and sophomores for the Imaging Sciences Pathway.
