Pre-Learning Stress That Is Temporally Removed from Acquisition Impairs Fear Learning.

Few studies have examined the time-dependent effects of stress on fear learning. Previously, we found that stress immediately before fear conditioning enhanced fear learning. Here, we aimed to extend these findings by assessing the effects of stress 30 min prior to fear conditioning on fear learning and fear generalization.

Genetic mapping of , a pupal lethal mutation in .

An EMS mutagenesis screen was conducted in to identify growth control mutants. The multi-institution Fly-CURE consortium phenotypically characterized the mutant using the system which displayed a mutant lethal phenotype with reduced head development, and darkened ocular tissue. Complementation mapping was conducted to identify the affected gene.
