Insect brain modeling for cognitive robotics
… to create efficient robots. Analyzing animal brains leads to new control systems that could allow robots to be able to orient themselves, to take decisions, to survive alone, to complete dangerous missions, to be completely autonomous. Robot implementation could also lead to predictions, for …

Experience-Dependent Plasticity in the Mushroom Bodies of the Honey Bee Brain
I am interested in the mechanisms that modify brain structure in response to experience. The model organism under study is Apis mellifera, the European honey bee. The honey bee has a rich behavioral repertoire that can easily be studied both in the laboratory and under natural conditions. The goal …

IMPACT OF PESTICIDES ON THE NEURAL STRUCTURE OF THE HONEY BEE, APIS MELLIFERA
… in the central nervous system of insects. Its use is controversial because it is a suspected contributor to the global decline of non-target pollinator populations. Sublethal doses of fipronil reduce colony fitness and impair learning and memory in the honey bee, Apis mellifera. …

Transcriptional response to spatial learning and foraging in honey bees: molecular bases for adult neuroplasticity
… neuroplasticity in the adult and aging brain. In many species, some types of neuroplasticity typically decrease with age. Honey bees and other social hymenopterans, however, exhibit a reinstatement of structural plasticity in association with flight and foraging behavior. Adult …

The adaptive benefits of adult structural plasticity in the mushroom bodies of freely behaving forager honey bees
The mushroom bodies (MBs) are insect brain regions associated with sensory integration and learning. The dendrites of the intrinsic MB neurons (the Kenyon cells) are in the calycal neuropil, where they receive input from primary sensory neuropils. The calyces are larger in older forager honey bees …

Caste-Specific Expression Of Coding And Noncoding Genes In Ant Brains
… can give rise to multiple phenotypes. Social insects are an ideal model system for epigenetics, as their colonies contain individuals with highly similar genomes but divergent behaviors and phenotypes. Harpegnathos saltator in particular provides opportunities for studying epigenetic control …

Modelling of bio-inspired vision system for velocity estimation.
Although motion processing in insects has been extensively studied for over almost 40 years, velocity detection in insects and how the insect brain computes the velocity of a moving feature, independent of its size or contrast, is a major enigma that remains unsolved. This study examines the …

Postembryonic Development and Adult Plasticity of the Mushroom Bodies in the Honey Bee Brain
… bodies are distinctive, paired neuropils in the insect brain. Convergence of numerous sensory modalities in the mushroom bodies indicates that they may be a center for sensory integration. Ablation and lesioning experiments have also established a role for this brain region in olfactory …

Mushroom body expansion and the cognitive ecology of Heliconius butterflies
… 50 species, exhibit a marked expansion of an insect brain structure called the mushroom bodies (MBs), which are 3-4 times larger than in other Lepidoptera, including closely related Heliconiini genera. MBs are known to play a role in learning and memory, particularly in olfactory contexts, …

Functional analysis of embryonic brain development in Tribolium castaneum
Das Gehirn eines Tieres ermöglicht unter anderem die Steuerung von komplexen Verhaltensweisen wie beispielsweise Orientierung und gerichtete Bewegungen. In Insekten wurde für jene Prozesse ein übergeordnetes Zentrum entdeckt, das Zentralkomplex genannt wird. Es besteht aus fünf neuropilären …

Pharmacological studies on the contribution of the neuropeptide proctolin to the cephalic control of singing behavior in grasshopper Chorthippus biguttulus (L.1758)
Das artspezifische Gesangsverhalten der Feldheuschrecke Chorthippus biguttulus läßt sich sowohl bei Männchen als auch bei Weibchen durch Injektionen des Pentapeptids Proktolin in das zentrale Protozerebrum auslösen. Das stimulierte Verhalten entspricht bezüglich der seiner zeitlichen Struktur und …

Neurogenese, Wachstum und Integration von lokalen Nervenzellen in einem multisensorischen Neuropil im zentralen Gehrin adulter Insekten.
Die Paarweisen säulensartigen Pilzkörper (MBs) des Insektgehirns stellen ein dominierendes neuropiles für multimodal sensorische Integration, die am wichtigsten für die Organisation des olfactorischen Verhaltens und für Gedächtnis und das Lernen. Die MBs enthalten immer eine Kategorie lokale …
