Understanding how smell or taste translates into behavior remains challenging. We have
developed a behavioral paradigm in Drosophila larvae to investigate reception and …

Neuropeptides, many of which are conserved among vertebrate and invertebrate animals,
are implicated in the regulation of motivational states that selectively facilitate goal-directed …

Odors are highly evocative, yet how and where in the brain odors derive meaning remains
unknown. Our analysis of the Drosophila brain extends the role of a small number of hunger …

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

All organisms continuously have to adapt their behavior according to changes in the
environment in order to survive. Experience‐driven changes in behavior are usually …

Background Animal olfactory systems detect volatile environmental chemicals and integrate
this information to direct the discovery of food and mates as well as danger avoidance …

Highlights•Starvation reduces aversive odor sensitivity and increases activity to food
odors.•Odors are categorized according to their behavioral relevance in the lateral …

Most animals are endowed with an olfactory system that is essential for finding foods,
avoiding predators, and locating mating partners. The olfactory system must encode the …

In the following we describe the methodological details of appetitive associative olfactory
learning in Drosophila larvae. The setup, in combination with genetic interference, provides …

Associative plasticity is a basic characteristic of behaviour. We analysed associative
olfactory learning in larval Drosophila, using a reciprocal conditioning assay. One group of …
