Perceptual and motor intentional processing in dorsal pulvinar
(2019-06-27)The pulvinar is the largest thalamic structure in the center of the brain, reciprocally connected to a large diversity of cortical areas. It has grown more than other subcortical structures during primate evolution, which ... -
Peripheral nervous system control for neuroprostheses
(2017-09-21)Amputee patients who have lost a hand or arm are severely impaired in their daily life, as they lose the ability to grasp and interact with their environment. While the use of electromyographically controlled prosthetic ... -
Perturbation Growth and Prediction of Extreme Events
(2018-11-15)Extreme events occur in a variety of dynamical systems. Here we employ quantifiers of chaos to identify changes in the dynamical structure of complex systems preceding an extreme event. -
Perturbation of Pattern Formation in Dictyostelium Discoideum via Flow and Spatial Heterogeneities
(2020-04-07)In this thesis, we investigate the signalling process of the social amoeba Dictyostelium discoideum (D. discoideum) as a model reaction-diffusion-advection system. Colonies of these cells are an excitable medium that ... -
Pharmacological alterations of neuroplasticity in the human motor cortex induced by dopaminergic and cholinergic agents
(2011-03-03)Dopamine and Acetylcholine are the major neuromodulators in the human central nervous system which strongly influence neuroplasticity. Several factors including subreceptor specificity, ... -
Pharmacologically controlled neurotrophic factor gene therapy for Parkinson's disease
(2019-07-24)During the PhD thesis, two projects were carried out. In the first project, an inducible AAV-5 vector for expression of GDNF, under control of the approved small molecule drug mifepristone, was evaluated in rats. GDNF ... -
Pharmacotreatment of a mouse model of Rett syndrome with the radical scavenger Trolox: Detailed assessment of potential merits in vitro and in vivo
(2015-04-27)Rett syndrome is a severe neurodevelopmental disorder, with an incidence of ~1/1000 female births, in which most patients carry mutations in the methyl-CpG binding protein 2 gene. No cure exists so far. Rett girls are born ... -
Phase Separation Studied by Nuclear Magnetic Resonance
(2024-01-04)Signal transduction by the ligated B cell receptor (BCR) depends on the pre-organization of its intracellular components, such as the effector proteins SLP65 and CIN85 within phase-separated condensates. These liquid-like ... -
Phenotype-based genetic association studies in schizophrenia: Proof-of-principle for cognition-relevant genes.
(2011-05-02)Schizophrenia is the collective term for a heterogeneous group of mental disorders with a still obscure biological basis. In particular, the specific contribution of risk or candidate gene ... -
Phenotypic and Functional Characterization of Natural Killer Cell Receptors in Human and Rhesus macaque
(2024-02-05)Activating killer immunoglobulin-like receptors (KIRs) cannot transmit signals directly but through signaling motifs. Since human activating KIRs lack signaling molecules, their transmembrane lysine residue pairs with ... -
Phosphoketolase - A mechanistic update
(2018-08-22)The thiamine diphosphate (ThDP)-dependent enzyme phosphoketolase catalyzes the phosphorolytic cleavage of fructose-6-phosphate and/or xylulose 5-phosphate under the generation of the high-energy metabolite acetyl phosphate, ... -
Phospholamban – Characterization of the Potential Interaction Partner SLMAP
(2024-10-10)The identification of novel PLN interaction partners is of high importance to understand how it is regulated on a molecular level and to develop new therapeutic strategies for cardiomyopathy. SLMAP, a novel putative PLN ... -
Phosphorylation of Synaptotagmin 4 captures transiting dense core vesicles at active synapses
(2017-03-03)Synaptic modulation requires fast recruitment of neuronal dense core vesicles (DCVs) containing various neuropeptides and neurotrophins at nerve terminals. DCVs undergo long-range trafficking in axons to deliver cargoes ... -
Phylogenetic studies of the vesicular fusion machinery
(2010-10-01)The eukaryotic cell consists of a large system of membrane delimited compartments. Material exchange between these compartments is mediated by intracellular trafficking vesicles. These ... -
Physiological Classification of Retinal Ganglion Cells in the Salamander Retina
(2016-04-13)The retina is a complex neural network, responsible for breaking down the visual scene into its distinctive features such as local contrast, motion and color. The retinal ganglion cells form the output layer of this ... -
Physiological functions of the adrenocortical circadian clock
(2014-09-10)In the course of evolution most organisms have evolved endogenous circadian clocks that help them to anticipate daily environmental changes in light, temperature and food availability and therefore adjust physiology and ... -
Plasma Factors as Endogenous Agonists and Modulators of TLR4 Signaling in Microglia
(2010-06-30)Toll-like receptors (TLRs) comprise a family of pattern recognition receptors (PRRs) which recognize pathogen-associated molecular patterns (PAMPs) an assortment of evolutionary conserved ... -
Plasticity of Dopamine-Releasing Central Brain Neurons Underlying Adaptational Feeding-Related Behavior in Drosophila Melanogaster
(2020-05-07)All organisms have to adapt and adjust behaviors to changing environmental conditions. Foraging and feeding behaviors are one of the most adaptive behaviors when changes in nutrient sources occur. Neuronal and behavioral ... -
Plasticity-dependent modulation of mitochondrial biogenesis determining motor neuron function and vulnerability
(2016-10-10)Axon terminals are likely the compartments of highest energy demand in the particularly active and polarized cells that are motor neurons. Paradoxically, although the particularly high-energy demand of motor neurons could ... -
Pore-spanning lipid membranes as a tool to study membrane permeabilization by antimicrobial peptides
(2017-09-06)Antimicrobial peptides (AMPs) have a high therapeutic potential in combating microbial diseases. Their modes of action are still not well understood, and screening methods to identify and improve AMPs are needed. This work ...
