  • A century later another surprise: A non-visual behavioral function of the white gene 

    Jenkins, Jennifer; Diegelmann, Soeren; Zars, Troy Daniel (University of Missouri--Columbia. Office of Undergraduate Research, 2005)
    Discovery of the white mutation in Drosophila melanogaster has broadly influenced our understanding of the mechanisms of inheritance. We recently discovered a role of the white gene in memory formation. Thus, the white ...

  • Characterizing serotonin in the fruit fly brain [abstract] 

    Sable-Smith, Alex; Zars, Troy Daniel (University of Missouri--Columbia. Office of Undergraduate Research, 2007)
    The biogenic amines serotonin (5-HT) and dopamine (DA) have been implicated in the formation of place memories in Drosophila melanogaster. However, stronger evidence exists in support of 5-HT as the more essential factor ...

  • The effects of sensitization on habituation using the olfactory jump reflex in Drosophila 

    Truesdale, Angela; Schwaerzel, Martin; Zars, Troy Daniel (University of Missouri--Columbia. Office of Undergraduate Research, 2004)
    Memories can arise from simpler habituation and sensitization training as well as associative classical conditioning. However, in a complex environment, animals receive sensory cues in a fashion that can be more accurately ...

  • Reinforcement signaling in Drosophila 

    Sitaraman, Divya, 1981- (University of Missouri--Columbia, 2010)
    Memory performance levels can reliably match the intensity / amount/ probability of reinforcement. Interestingly, experience with a reinforcer unpaired from any predictors can enhance or impair later associative learning. ...

  • Unequal reinforcement values from equally warm and cool temperatures in Drosophila 

    Carmichael, Giselle; Zars, Melissa; Zars, Troy Daniel (University of Missouri--Columbia. Office of Undergraduate Research, 2004)
    Insects inhabit extreme temperature environments and have evolved mechanisms to survive there. When temperatures either rise or fall, small insects alter their behavior within seconds to avoid, in extreme situations, ...

  • Using simple nervous systems to investigate the neural basis of behavior 

    McClellan, Andrew; Schul, Johannes; Schulz, David; Zars, Troy Daniel (2010)
    The human brain is remarkable, both in the sense that it helps us with a lifetime of decisions and memories, but also that it allows us to contemplate how the brain itself works. One concludes, however, pretty quickly ...
