Neural dynamics of social behavior: An evolutionary and mechanistic perspective on communication, cooperation, and competition among situated agents
Wischmann, Steffen (2008)<p>Social behavior can be found on almost every level of life, ranging from microorganisms to human societies. However, explaining the evolutionary emergence of cooperation, communication, or competition still challenges ... -
Neural mechanisms involved in visual learning in the cichlid fish Pseudotropheus zebra
Calvo, Roberta (2023-12-20)Although several studies have investigated the cognitive abilities in fish, not so much is known about where the cognitive information is processed in the brain. For this PhD thesis I assessed visual learning and its neural ... -
Neural Network Growth, Structure and Dynamics
Kalle Kossio, Felipe Yaroslav (2022-07-13)The evolutionary emergence of the nervous system provided individual organisms with a substrate for the development of complex behaviors and fast adaptations to dynamic environments. One of the main ways a nervous system ... -
Neural Network-based Signal Isolation and Cross Section Estimation of the tH Process with the ATLAS Detector
Kirfel, Christian (2024-02-29)A measurement of the single top quark production in association with a Higgs boson (tH) gives insight into the properties of not only the top quark but also the Higgs boson. The associated production is sensitive to the ... -
Neurale Linienselektion humaner embryonaler Stammzellen
Limbach, Nina (2012-03-29)Im Rahmen dieser Dissertation sollte ein effektives Verfahren zur Aufreinigung hESC-abgeleiteter neuronaler Populationen entwickelt werden. Hierfür wurden zwei Strategien eingesetzt. Bei der Promotor-basierten Selektion, ... -
Neuroanatomie und Funktionsmorphologie Peripherer Rezeptorneurone mit Direkten Projektionen in das Protocerebrum des Insektengehirns
Hinz, Marcel (2023-04-20)Zur Wahrnehmung unterschiedlicher thermischer Reize hat sich bei Insekten eine Reihe von Thermorezeptoren entwickelt. Der pyrophile („feuerliebend“) „Australische Feuerkäfer“ (<em>Merimna atrata</em>) besitzt paarige ... -
Neurobiology and modeling of cuticular hair sensilla of scorpions: Response characteristics and implications for biomimetic design
Kladt, Nikolay (2008)<p>In this thesis, the neurobiology of mechanoreceptive sensilla on the pectines of the scorpion <i>Pandinus cavimanus</i> was examined. The morphology of the pectines, the innervation and morphology of the sensilla as ... -
Neuroinflammation in Mausmodellen der Metachromatischen Leukodystrophie
Stein, Axel (2016-10-18)Arylsulfatase A (ASA) katalysiert die Desulfatierung von 3-O-Sulfogalaktosylceramid (Sulfatid), einem Hauptbestandteil der Myelinscheide. Ein Verlust der Aktivität von ASA führt zu der lysosomalen Speichererkrankung ... -
Neuroinvasion and cerebral ischemia as possible sources for α-synuclein prions in Parkinson’s disease
Lohmann, Stephanie (2021-07-13)In synucleinopathies such as Parkinson’s disease misfolding of α-synuclein, normally a cellular and soluble protein, leads to the accumulation of insoluble protein aggregates and to central nervous system disease (CNS). ... -
Neuronal and Circuit Architecture Underlying Feeding Behavior in Drosophila
Miroschnikow, Anton (2021-06-28)Feeding is elemental for survival and one of the most common activities of animals. Little is known about the organization of neuronal circuits controlling feeding behavior in the cen-tral nervous system. This study maps, ... -
Neuronal functions of RIM3γ and RIM4γ
Michel, Katrin (2015-09-25)The large isoforms of the Rab3 interacting molecule (RIM) family, RIM1α/β and RIM2α/β are integral components of the cytomatrix of the presynaptic active zone. Through multiple interactions with other active zone proteins ... -
Neuronal Systems Potentially Involved in Autism Spectrum Disorder
Liemersdorf, Christian (2017-06-01)Pfn2 is a brain specific actin binding protein involved in actin dynamics. The Pfn2 knock-out mouse model shows an autistic-like phenotype with all of the features commonly reported in autism patients such as social and ... -
Neuronale Netze mit erweiterten bayesschen Methoden für reale Datensammlungen
Weber, Karsten Ernst (2004)Zu zahlreichen Problemen, die bei der Verarbeitung von realen Trainingsdaten durch neuronale Netze auftreten können, und die bisher in der Literatur nicht oder nicht ausreichend diskutiert wurden, werden Lösungen präsentiert. ... -
Neuropeptides in stress reactivity: Role of enkephalin in response to chronic stress
Melo de Carvalho, Irene (2015-01-29)The incidence of mood pathologies, such as chronic anxiety and major depression, is a serious health problem in modern societies. The knowledge about the molecular mechanisms involved in the development of these disorders ... -
Neuroprotective Effects of Polysialic Acid and SIGLEC-11 in Activated Phagocytic Cells
Shahraz, Anahita (2016-03-30)SIGLEC-11 is an inhibitory receptor expressed on microglial cells and macrophages and can recognize α 2→8 linked Sias structures. The surface of neuron is decorated by different lengths of polySias. PolySia-SIGLEC-11 ... -
Die neurotoxische Wirkung von Sphingosin-1-phosphat: Mögliche Zusammenhänge zwischen Glykosphingolipid-Metabolismus und neurodegenerativen Prozessen
Hagen, Nadine (2010-11-16)Kleinhirnneuronen von S1P-Lyase-defizienten Mäusen und ein synthetischen Sphingosin Analogon wurden in dieser Arbeit verwendet, um die Toxizität von S1P, einem bioaktiven Sphingolipid, in terminal differenzierten Nervenzellen ... -
Neurotransmitter receptors in mouse models of Alzheimer’s disease
von Staden, Elena (2014-06-20)Alzheimer's disease (AD) is the most common form of dementia. The disease occurs in a common sporadic and a familiar form (FAD). Both forms show a very similar clinical and pathological picture, with ß-amyloid (Aß) plaques ... -
