...Sabine Hofer; Uwe Homberg SUMMARY The accessory medulla (AMe), a small neuropil in the optic lobe, houses the master circadian clock in the brain of the cockroach Leucophaea maderae and controls circadian rhythms in locomotor activity. Recently,members of the orcokinin family of crustacean...

...Thomas Reischig; Monika Stengl SUMMARY The presence of an endogenous circadian clock in the brain of an animal was first demonstrated in the cockroach Leucophaea maderae . However, the clock's cellular basis remained elusive until pigment-dispersing hormone-immunoreactive neurons, which express...

...Bernhard Petri; Uwe Homberg; Rudolf Loesel; Monika Stengl SUMMARY Accumulating evidence suggests that the accessory medulla is the location of the circadian pacemaker in the fruit fly Drosophila melanogaster and the cockroach Leucophaea maderae . γ-Aminobutyric acid(GABA) and Mas-allatotropin...

...Åsa M. E. Winther; Dick R. Nässel ABSTRACT Tachykinin-related peptides (TRPs) in the locust Locusta migratoria and the cockroach Leucophaea maderae have stimulatory effects on some muscles that are not innervated by TRP-containing neurons. Thus, these tissues may be affected by circulating TRPs...

...Dick R. Nässel; Manfred Eckert; J. Eric Muren; Heinz Penzlin ABSTRACT Nine tachykinin-related peptides (TRPs) have been isolated from the brain and intestine of the cockroach Leucophaea maderae . In the present investigation, two of the nine TRPs, LemTRP 1 and 5, were tested for their ability...

... immunoreactivity were measured in extracts of different portions of the nervous system, in the retrocerebral complex and in the hemolymph of the cockroach Leucophaea maderae. The brain contains about 1.9pmol of immunoreactive material while the ganglia of the ventral nerve cord each contain less than 10...
