Experimental investigation on the influence of rotation on thermal convection
(2022-10-18)We report on experimental measurements of rotating Rayleigh-Bénard convection to study the influence of the Coriolis force on the heat transport and the flow structure. Two experimental setups were used. The first is a ... -
Exploration of cargo spectrum and NES patterns recognized by the exportin CRM1
(2014-10-15)The nuclear envelope (NE) subdivides eukaryotic cells into a nuclear and a cytoplasmic compartment, forcing material exchange between these two compartments to proceed through the nuclear pore complexes (NPCs). While ... -
Exploring the human Hsp70-Hop-Hsp90 system for Tau recognition
(2022-03-22)Molecular chaperones are diligent helpers of the cell that ensure a well-balanced proteome by regulating protein production, protein folding, refolding and holding as well as protein degradation. In doing so, molecular ... -
Exploring the neural basis of touch through selective and stable genetic tagging in the chick somatosensory system
(2013-01-03)The assembly of circuitries for somatosensory perception relies on a complex interplay of neuronal diversification, specification, phenotypic modulation and establishment of precise connectivity patterns during embryogenesis. ... -
Expression and function of Rab3 interacting molecules and clarin-1 in inner hair cells
(2013-09-04)Hearing depends on faithful synaptic transmission at the inner hair cell (IHC) ribbon synapse, which is orchestrated by active zone proteins. RIM (Rab3 Interacting Molecules) is one of the active zone proteins and proposed ... -
Expression and properties of neuronal MHC class I molecules in the brain of the common marmoset monkey
(2009-11-13)Several recent studies have highlighted the important role of immunity-related molecules in synaptic plasticity processes in the developing and adult rodent brain. It has been suggested that neuronal MHC (major ... -
Extending Resolution in All Directions: Image Scanning Microscopy and Metal-induced Energy Transfer
(2019-03-18)Fluorescence microscopy is a powerful tool in the life sciences and is used to study structure and function on length scales from cells down to single molecules. In recent years, fluorescence microscopy has seen enormous ... -
Eye, hand and space representations and causal interference in bihemispheric pulvinar-parietal circuitry
(2019-05-29)Recent research proposes that a proper action is the outcome of continuous competition between multiple frontoparietal neuronal representations of possible response options and this competition is biased by the input ... -
Fast and Robust Multi-Dimensional Cardiac Magnetic Resonance Imaging
(2020-09-02)Magnetic Resonance Imaging (MRI) has become an almost indispensable tool in hospitals worldwide as it provides significant and unique information for the assessment of various disease and injuries. However, MRI is an ... -
Feature Selectivity in Synthetic Neuronal Networks
(2024-06-06)A fundamental property of neurons in the primary visual cortex is their preference for orientation of edges. In primates and carnivores orientation selective neurons are organized into functional domains that are arranged ... -
Feature-based attention in primate visual cortex
(2016-07-06)The scope of this thesis, after a brief summary of the core ideas of top-down attentional control is given (Chapter 2.1), is to shed some light on the cortical control circuit underlying the deployment of feature-based attention. ... -
Flows, morphology, and memory: study of a living network
(2020-06-22)The complex behaviour of the slime mould Physarum polycephalum, a simple eukaryote, has been puzzling researchers since its discovery. The giant unicellular, but multinucleate organism is highly successful at tackling ... -
Fluctuations and Oscillatory Instabilities of Intracellular Fiber networks
(2015-11-10)Biological systems with their complex biochemical networks are known to be intrinsically noisy. The interplay between noise and dynamical behavior is particularly relevant in the case of chemotactic amoeboid cells as their ... -
Fluorescence correlation spectroscopy for studying intermediate filament assembly
(2017-08-10)Intermediate filaments play a central role in the cytoskeleton of eukaryotic cells. Together with microtubules and actin filaments they determine the mechanical properties of cells. Microtubules are also the guiding tracks ... -
Fluorescence Lifetime Single Molecule Localisation Microscopy
(2021-03-26)In conventional fluorescence microscopy, species are distinguished by colour. While these images provide an abundance of information about the sample, they are, in many aspects limited by artefacts and resolution, and some ... -
Fluorescence spectroscopic studies of protein conformational dynamics
(2013-10-31)The folding of a protein into its native structure is the fundamental prerequisite for its functionality. The polypeptide chain itself contains the chemical information necessary for spontaneous folding of the protein. ... -
Food Distribution in Ant Colonies: Trophallaxis and Self-Organization
(2017-09-14)Roughly one hundred million years ago, solitary insect species evolved social interactions that enabled the formation of colonies. A main reason for this advance was their ability to feed each other with previously ... -
Force information integration in the primate fronto-parietal reach network
(2023-11-10)The primate sensorimotor system relies on force predictions, when executing a motor command with a certain force. Yet it remains unclear if the sensorimotor system uses these force predictions to prepare a motor command ... -
Forces in Cellular Growth and Division
(2016-02-05)Under confinement cell populations exert growth forces onto their surroundings. Confined cell populations can be found plentiful in nature, e.g. tumors embedded in healthy tissues, microbial populations in stone cavities ... -
Formation, regulation and dynamics of phase separated postsynaptic density condensates with Tau and Fyn
(2024-11-22)Alzheimer’s disease is characterized by memory loss and cognitive impairments. The cognitive deficits and synaptic dysfunction are associated with the excitotoxicity mediated by NMDA (N-methyl-D-aspartate) receptors on the ...
