This review focuses on neuropeptides and peptide hormones, the largest and most diverse
class of neuroactive substances, known in Drosophila and other animals to play roles in …

Central and peripheral insulin-like peptides (ILPs), which include insulin, insulin-like growth
factor 1 (IGF1) and IGF2, exert many effects in the brain. Through their actions on brain …

The digestive tract plays a central role in the digestion and absorption of nutrients. Far from
being a passive tube, it provides the first line of defense against pathogens and maintains …

Employing the clear, student-friendly style that made previous editions so popular, Insect
Physiology and Biochemistry, Fourth Edition presents an engaging and authoritative guide …

Internal nutrient sensors play important roles in feeding behavior, yet their molecular
structure and mechanism of action are poorly understood. Using Ca 2+ imaging and …

Internal physiological states influence behavioral decisions. We have investigated the
underlying cellular and molecular mechanisms at the first olfactory synapse for starvation …

Studies of feeding behavior in genetically tractable invertebrate model systems have been
limited by the lack of proper methodology. We introduce the Capillary Feeder (CAFE), a …

Behavioral expression of food-associated memory in fruit flies is constrained by satiety and
promoted by hunger, suggesting an influence of motivational state. Here, we identify a …

Studies of neuropeptide and peptide hormone signaling are coming of age in Drosophila
due to rapid developments in molecular genetics approaches that overcome the difficulties …

Organisms adapt to changing environments by adjusting their development, metabolism,
and behavior to improve their chances of survival and reproduction. To achieve such …
