Ultrafast Multichannel Optogenetic Stimulation of the Auditory Pathway for Optical Cochlear Implants
(2019-01-14)In case of profound sensorineural hearing loss and deafness, cochlear implants (CIs) partially restore hearing and provide missing auditory information to the brain. Electrical stimulation of the spiral ganglion neurons ... -
Ultrastructural Characterization of The Output of VIP Expressing Interneurons in Mouse Barrel Cortex
(2017-11-15)Based on this preliminary result, a quantitative immunoelectron microscopy study was adopted to comprehensively characterize the output of VIP interneurons across the whole laminae of mouse barrel cortex. Using VIPcre/YFP ... -
Ultrastructural study of synaptic vesicle dynamics in murine inner hair cell ribbon synapses under sustained stimulation
(2023-07-11)Transmission of auditory information relies in the correct functioning of inner hair cell (IHC) rib-bon synapses, which mediate synaptic vesicle release in an indefatigable manner. The name-giving synaptic ribbon and the ... -
Undersampled Radial STEAM MRI: Methodological Developments and Applications
(2018-03-09)The diffusion-weighted (DW) single-shot stimulated echo acquisition mode (STEAM) sequence offers DW MRI without susceptibility artifacts which severely hamper diagnostic applications when using conventional echo-planar ... -
Understanding Nucleosome Assembly Regulation in Drosophila melanogaster
(2022-06-24)Nucleosomes consist of a complex of DNA and an octameric core of histone proteins, which represent the basic subunit of chromatin. The N-terminal tails of histones are target for chemical modifications, which play an ... -
Universal Computation and Memory by Neural Switching
(2011-10-21)Complex heteroclinic networks of connected saddle states persistently emerge in a broad range of dynamical systems and may reliably encode ``memory items'' as specific switching trajectories. ... -
Unraveling details of CIN85/CD2AP assistance to SLP65-mediated B cell activation
(2020-06-18)The hallmark of adaptive immunity is the production of specific antibodies. This process is initiated upon the ligation of the B cell antigen receptor (BCR) which activates multiple intracellular signaling cascades through ... -
Unraveling the Role of TET3 in regulating EndMT in Cardiac Fibrosis
(2023-02-10)DNA methylation and subsequent silencing of gene expression is associated with disease states including tumorigenesis and fibrosis. Although DNA methylation is a dynamic and reversible process, the mechanisms of and ... -
Unravelling the Role Cortical Myelination Plays in Higher Brain Functions
(2021-07-07)Myelination is a process within the nervous system, where axons are ensheathed by lipid-rich, multi-spiral wraps called myelin. Its main role is to expedite impulse propagation within circuitries and allow for faster ... -
Untangling neuronal diversity: a quantitative electrophysiological and morphological characterization of VIP expressing interneurons
(2017-03-21)VIP expressing interneurons are an essential component of cortical circuitry. This distinct subgroup of inhibitory interneurons was always described as the most heterogeneous subgroup of inhibitory interneurons. However, ... -
USPL1, a novel SUMO isopeptidase
(2009-06-23)Small Ubiquitin-like Modifiers (SUMO) are 10 kDa proteins that are covalently attached to hundreds of intracellular proteins to regulate their function. In mammals, three members of the ... -
UV and chemical crosslinking mass spectrometry for the analysis of protein-nucleic acid interactions
(2024-07-12)Protein-nucleic acid interactions are a key part of essential cellular processes and their disturbance often results in the development of diseases. Crosslinking mass spectrometry (XL-MS)-based approaches have become ... -
Validation of novel protein-protein interactions in Bacillus subtilis
(2023-01-12)Protein-protein interactions are the basis for many biological processes in the cell. Understanding these interactions is crucial for the general analysis of how the cell functions and the potential identification of ... -
Vav guanine nucleotide exchange factors control B cell antigen receptor-induced Ca2+-signaling
(2016-03-15)Differentiation of B cells into antibody secreting plasma cells is an indispensable step to cope with pathogens. Antigen binding to the B cell antigen receptor (BCR) initiates signaling cascades leading in combination with ... -
Vergleichende Untersuchungen zur Regulation der SNARE-Komplexbildung durch Sec1/Munc18-Proteine
(2009-07-01)Membrane fusion events between various intracellular compartments in eukaryotic cells are mediated by two conserved protein families: SNARE- and Sec1/Munc18 (SM)-proteins. The SNARE ... -
Vimentin Intermediate Filament Softening - Recovery Behavior and Post-Translational Modifications
(2021-09-16)The capability of eukaryotic cells to resist large deformations, to transport intracellular cargo and to adapt the cell shape, for example during migration, depends on the cytoskeleton, a composite network of three types ... -
Vision, cortical maps and neuronal plasticity in Bassoon and PSD-95 mutant mice.
(2014-03-21)Bassoon mutant mice (Bsn-/-) display a striking loss of synaptic ribbons in photoreceptor terminals, which impairs signal transduction through the retina (Altrock et al., 2003; Specht et al., 2007). Therefore we assessed ... -
Visual and Auditory Perceptual Decision-Making in The Human Brain as Invesitgated by fMRI and Lesion Studies
(2017-07-27)Perceptual decision-making refers to the act of choosing one option from a set of alternatives based on the available sensory information. In this manuscript, we used model-based functional magnetic resonance imaging and ... -
