The invention provides a method of identifying a compound that alters vigilance. The method consists of contacting an invertebrate with a candidate compound, evaluating a vigilance property in the contacted invertebrate, and determining if the candidate compound alters the vigilance property in the contacted invertebrate. A candidate compound that alters the vigilance property in the contacted invertebrate is identified as a compound that alters vigilance. The invention also provides a method of identifying a vigilance enhancing compound that modulates homeostatic regulation or a vigilance diminishing compound that modulates homeostatic regulation. The method consists of contacting an invertebrate with a compound that increases or decreases vigilance, and determining the effect of the compound on a homeostatic regulatory property of vigilance. A compound that alters the homeostatic regulatory property is characterized as being a vigilance enhancing compound or a vigilance diminishing compound that modulates homeostatic regulation.

Methods for identifying compounds that modulate vigilance states

The present invention provides a method of identifying a compound that modulates a mammalian vestibular system. The method consists of administering a test compound to an invertebrate, and measuring a geotactic behavior of the invertebrate, where a compound that modulates the geotactic behavior of the invertebrate is characterized as a compound that modulates a mammalian vestibular system. The invention also provides a method of identifying a gene that modulates a mammalian vestibular system consisting of obtaining a first and a second strain of an invertebrate; subjecting the first and second invertebrate strains to conditions in which the first strain exhibits a geotactic behavior different than a geotactic behavior exhibited by the second strain; measuring gene expression levels in the first and second strains, and identifying one or more genes that are differentially expressed in the first strain relative to the second strain, whereby a mammalian gene having substantially the same nucleic acid sequence as the one or more differentially expressed genes modulates the mammalian vestibular system.
