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 …

The cockroach Leucophaea maderae was the first animal in which lesion experiments
localized an endogenous circadian clock to a particular brain area, the optic lobe. The neural …

Locomotor activity rhythms of the cockroach Leucophaea maderae are orchestrated by two
bilaterally symmetric, mutually coupled, circadian pacemakers. They lie in the optic lobes of …

The circadian rhythm of locomotor activity in the cockroach Leucophaea maderae is controlled
by bilaterally symmetric, apparently directly coupled, circadian pacemakers in the optic …

Understanding the processes that underlie the current distribution of genetic diversity in
endangered species is a goal of modern conservation biology. Specifically, the role of …

… superior median protocerebrum (Reischig and Stengl 2003a). … circuits within the AMe (Reischig
and Stengl 2003b). First, … very strong PDH immunoreactivity (Reischig and Stengl 2003b)…

Crustaceans have frequently been used to study the neuroethology of both agonistic behavior
and circadian rhythms, but whether their highly stereotyped and quantifiable agonistic …

To provide a framework for a cellular analysis of the accessory medulla, which is the presumptive
circadian pacemaker of hemimetabolous insects, we have studied this neuropil and its …

Long-term monitoring of host-parasite interactions is important for understanding the
consequences of infection on host fitness and population dynamics. In an eight-year survey of the …

Lesion and transplantation studies in the cockroach, Leucophaea maderae, have located its
bilaterally symmetric circadian pacemakers necessary for driving circadian locomotor …
