Confocal microscopy in large insect brains: Zinc–formaldehyde fixation improves synapsin immunostaining and preservation of morphology in whole-mounts
  • S. Ott
  • Biology, Medicine
  • Journal of Neuroscience Methods
  • 30 July 2008
Confocal microscopy enables the analysis of immunofluorescence in whole-mount brains and is therefore widely used in the functional and comparative neuroanatomy of invertebrates. Three difficulties,Expand

Serotonin Mediates Behavioral Gregarization Underlying Swarm Formation in Desert Locusts
Desert locusts, Schistocerca gregaria, show extreme phenotypic plasticity, transforming between a little-seen solitarious phase and the notorious swarming gregarious phase depending on populationExpand

Timed and Targeted Differential Regulation of Nitric Oxide Synthase (NOS) and Anti-NOS Genes by Reward Conditioning Leading to Long-Term Memory Formation
In a number of neuronal models of learning, signaling by the neurotransmitter nitric oxide (NO), synthesized by the enzyme neuronal NO synthase (nNOS), is essential for the formation of long-termExpand

  • Biology, Medicine
  • Proceedings of the Royal Society B: Biological…
  • 22 October 2010
The behavioural demands of group living and foraging have been implicated in both evolutionary and plastic changes in brain size. Desert locusts show extreme phenotypic plasticity, allowing brainExpand

Modeling Cooperative Volume Signaling in a Plexus of Nitric Oxide Synthase-Expressing Neurons
In vertebrate and invertebrate brains, nitric oxide (NO) synthase (NOS) is frequently expressed in extensive meshworks (plexuses) of exceedingly fine fibers. In this paper, we investigate theExpand

Nitric oxide synthase in the thoracic ganglia of the locust: Distribution in the neuropiles and morphology of neurones
  • S. Ott, M. Burrows
  • Biology, Medicine
  • The Journal of comparative neurology
  • 1 June 1998
Nitric oxide signaling is implicated in olfactory and visual pathways within the insect brain. In contrast, little is known about the distribution and function of nitric oxide synthase (NOS) in theExpand

Contralateral inhibition as a sensory bias: the neural basis for a female preference in a synchronously calling bushcricket, Mecopoda elongata
Imperfect synchrony between male calls occurs widely in acoustically courting crickets and bushcrickets. Males which are able to establish the temporal leadership usually attract more females inExpand

Critical role for protein kinase A in the acquisition of gregarious behavior in the desert locust
The mechanisms that integrate genetic and environmental information to coordinate the expression of complex phenotypes are little understood. We investigated the role of two protein kinases (PKs) inExpand

Nitric oxide synthase histochemistry in insect nervous systems: Methanol/formalin fixation reveals the neuroarchitecture of formaldehyde‐sensitive NADPH diaphorase in the cockroach Periplaneta
  • S. Ott, M. Elphick
  • Biology, Medicine
  • The Journal of comparative neurology
  • 24 June 2002
Formaldehyde‐insensitive NADPH diaphorase (NADPHd) activity is used widely as a histochemical marker for neuronal nitric oxide synthase (NOS). However, in several insects including the cockroachExpand

New Techniques for Whole-mount NADPH-diaphorase Histochemistry Demonstrated in Insect Ganglia
  • S. Ott, M. Elphick
  • Biology, Medicine
  • The journal of histochemistry and cytochemistry…
  • 1 April 2003
Fixation-resistant NADPH-diaphorase (NADPHd) activity is used widely as a marker for nitric oxide synthase (NOS). In frozen sections, NADPHd histochemistry yields high anatomic definition. InExpand
