Sensory Integration Regulating Male Courtship Behavior in Drosophila
The courtship behavior of Drosophila melanogaster serves as an excellent model system to study how complex innate behaviors are controlled by the nervous system. To understand how the underlying neural network controls this behavior, it is not sufficient to unravel its architecture, but also crucial to decipher its logic. By systematic analysis of how variations in sensory inputs alter the cour...
متن کاملMale Courtship Behavior in Drosophila
All animals exhibit innate behaviors that are specified during their development. Drosophila melanogaster males (but not females) perform an elaborate and innate courtship ritual directed toward females (but not males). Male courtship requires products of the fruitless (fru) gene, which is spliced differently in males and females. We have generated alleles of fru that are constitutively spliced...

All animals exhibit innate behaviors that are specified during their development. Drosophila melanogaster males (but not females) perform an elaborate and innate courtship ritual directed toward females (but not males).

متن کاملNeural Circuitry that Governs Drosophila Male Courtship Behavior
Male-specific fruitless (fru) products (Fru(M)) are both necessary and sufficient to "hardwire" the potential for male courtship behavior into the Drosophila nervous system. Fru(M) is expressed in approximately 2% of neurons in the male nervous system, but not in the female. We have targeted the insertion of GAL4 into the fru locus, allowing us to visualize and manipulate the Fru(M)-expressing ...
متن کاملMagnetoreception Regulates Male Courtship Activity in Drosophila
The possible neurological and biophysical effects of magnetic fields on animals is an area of active study. Here, we report that courtship activity of male Drosophila increases in a magnetic field and that this effect is regulated by the blue light-dependent photoreceptor cryptochrome (CRY). Naïve male flies exhibited significantly increased courtship activities when they were exposed to a ≥ 20...
