From brains to behavior: Cold Spring Harbor Protocols features methods for neuroscience researchOctober 02, 2007Research in the field of neuroscience is constantly expanding to provide knowledge about biological mechanisms that underlie our ability to experience and interact with the world around us. To facilitate such research, two neuroscience methods are featured in this month's release of Cold Spring Harbor Protocols. Both are freely accessible online (www.cshprotocols.org) and include movie clips that help to illustrate the procedures. The first protocol, available at http://www.cshprotocols.org/cgi/content/full/2007/20/pdb.prot4848, describes a step-by-step approach to prepare brain slices from rats or mice for growth in culture. Brain slice cultures, which are easy to prepare and maintain for several weeks or even months in the lab, allow researchers to examine the structure and function of neurons in their native environment. The brain slice culture protocol was contributed by Dr. Michael Dailey's group from the University of Iowa (http://www.biology.uiowa.edu/daileylab). His lab uses brain slice cultures in conjunction with high-resolution imaging and staining techniques to investigate changes that occur during the development of the central nervous system, as well as changes that occur after injury to the nervous system. Brain slice cultures can also be used to test the effects of various drugs or genetic backgrounds on brain function.
The second featured protocol is from Dr. Leslie Griffith's lab at Brandeis University (http://www.bio.brandeis.edu/griffithlab). It describes how to properly assess courtship behavior in male fruit flies. Because the behavior of male fruit flies is dependent on many environmental stimuli, it is important to measure courtship behavior under highly controlled conditions. Griffith's protocol describes how to control visual input, for example, by manipulating the light conditions under which the experiment takes place. Griffith's protocol, freely available at http://www.cshprotocols.org/cgi/content/full/2007/20/pdb.prot4847, also describes how to assemble a courtship chamber and discusses strategies for observing and measuring courtship behavior. It can be used to evaluate the effects of prior experience and genetic background on courtship, and will be useful to researchers who are interested in understanding the biological basis of behavior.

Stem Cells from Monkey Teeth Can Stimulate Growth and Generation of Brain Cells Researchers at the Yerkes National Primate Research Center, Emory University, have discovered dental pulp stem cells can stimulate growth and generation of several types of neural cells. Findings from this study, available in the October issue of the journal Stem Cells, suggest dental pulp stem cells show promise for use in cell therapy and regenerative medicine, particularly therapies associated with the central nervous system.

Social interactions can alter gene expression in the brain, and vice versa Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.
