Arousal can be described as an endogenously generated or exogenously induced change in behavioral responsiveness. Changes in levels of arousal, such as occur during sleep or attention, most likely accomplish adaptive functions common to most animals.

The fruit fly, Drosophila melanogaster, is equipped with a sophisticated olfactory sensory system that permits it to recognize and discriminate hundreds of discrete odorants. The perception of these odorants is essential for the animal to identify relevant food sources and suitable sites for egg-laying.

As bluntly summarized by a psychologist over a century ago, everyone knows what attention is [James (1890). The Principles of Psychology]. Attention describes our capacity to focus perception on one or a group of related stimuli while filtering out irrelevant stimuli. The ease we have in recognizing this astounding capacity in ourselves is matched by a

Flies of the genus Drosophila, particularly D. melanogaster, have been mainstays of biological research on aging for more than 80 years. However, what was striking for most of those years was how little concrete progress was made on the problem of aging using the normally powerful Drosophila model system.

Forward genetics in Drosophila has profoundly affected our understanding of circadian rhythms in this organism and, more generally, in the animal kingdom. Most Drosophila pacemaker genes were discovered through the isolation of gene variants affecting the free-running period of the circadian pacemaker. There are different ways to mutagenize flies.

A short summary on the present knowledge on spermatogenesis in Drosophila is given which also points out particular questions of interest in the context of this morphogenetic process. Such points of interest are the formation of lampbrush loops in primary spermatocytes, the chromosomal events during meiosis, the occurrence of chromatin rearrangements ...

Recent genetic and molecular data from Drosophila support the long-standing observations of morphology in suggesting that segmentation of the insect embryo proceeds in two phases. Organization of the cephalic segments uses a mechanism distinct from the familiar bierarchical cascade of segmentation genes that subdivides the trunk of the embryo.

The past year has been a spectacular one for Drosophila research. The sequencing and annotation of the Drosophila melanogaster genome has allowed a comprehensive analysis of the first three eukaryotes to be sequenced-yeast, worm and fly-including an analysis of the fly's influences as a model for the study of human disease.

Septic injury induces in Drosophila the rapid and transient transcription of several genes encoding potent antimicrobial peptides. Significant structural and functional similarities exist between the injury-induced signalling cascades leading to antimicrobial peptide gene expression in Drosophila and cytokine-induced expression of mammalian acute-phase

The functioning kidney requires proper organization in multiple cell types that mediate filtration and removal of wastes. Interest has increasingly focused on the podocyte as an important mediator of kidney function; defects in podocyte function likely mediate a broad palate of kidney dysfunctions.
