SIFamide receptor (SIFR) is a Drosophila G protein-coupled receptor for the neuropeptide
SIFamide (SIFa). Although the sequence and spatial expression of SIFa are evolutionarily …

SIFamides are a family of highly conserved neuropeptides in arthropods, and in insects are
mainly expressed in four medial neurons in the pars intercerebralis of the brain. Although …

Animal behavior is, on the one hand, controlled by neuronal circuits that integrate external
sensory stimuli and induce appropriate motor responses. On the other hand, stimulus …

This review is focussed on SIFamide. This neuropeptide was discovered as a result of an
extensive purification process, typical for 20th century physiology, of an extract of 350,000 …

SIFamide is the short name and also the C terminus of the Drosophila neuropeptide
AYRKPPFNGSIFamide. SIFamide has been isolated or predicted from various insects and …

Sleep, a reversible quiescent state found in both invertebrate and vertebrate animals,
disconnects animals from their environment and is highly regulated for coordination with …

Histamine and its two receptors, histamine-gated chloride channel subunit 1 (HisCl1) and
ora transientless (Ort), are known to control photoreception and temperature sensing in …

Background Sleep is an essential behavior that is found in all animals that have a nervous
system. Neural activity is thought to control sleep, but little is known about the identity and …

Circadian rhythms allow animals to coordinate behavioral and physiological processes with
respect to one another and to synchronize these processes to external environmental …

Sleep behavior is conserved throughout evolution, and sleep disturbances are a frequent
comorbidity of neuropsychiatric disorders. However, the molecular basis underlying sleep …
