SUMMARY:Cognitive Science Distinguished Speaker Series - Professor Edward Kravitz of Harvard University
DESCRIPTION:
 Dr. Edward Kravitz of Harvard University gives 
 a talk entitled "Genetic manipulations 
 in the fruit fly fight club: sex and war in a 
 single gene and other stories." The talk 
 will be held as a part of the Cognitive Science 
 Distinguished Speaker Series.\n
 \n
 Abstract 
 for talk: Male and female flies fight in same 
 sex pairings. Some of the behavioral patterns 
 seen during fights are the same in male and 
 female flies: some are sex selective. The 
 fruitless gene of the sex determination hierarchy 
 plays a role in determining whether flies 
 fight like males or females. Male flies establish 
 hierarchical relationships while females 
 do not. Learning and memory accompany the 
 establishment of these relationships, and defeated 
 flies develop a "loser mentality" 
 in which they lose all second fights. Decision 
 making of whether to court or fight in 
 male flies depends on cues from primary senses, 
 and also on the behavior of a second fly. 
 As in other species, amines serve roles in multiple 
 behaviors in flies. Using genetic methods, 
 the function of single amine neurons can 
 be altered, allowing definition of the behavioral 
 functions served by these neurons. These 
 and other topics will be covered in this seminar.\n
