Molecular Physiology of Synaptic Sound Encoding
(2025-04-10)Cochlear inner hair cells (IHCs) of the auditory system form specialised chemical synapses called ribbon synapses with type I spiral ganglion neurons (SGNs). These synapses encode sound information into neural signals for ... -
Optimal Control Methods for Biomolecular NMR Spectroscopy
(2025-04-04)Bio-molecular NMR studies are usually limited by the sensitivity and resolution, especially for concentration limited samples such as IDPs, in-cell samples and metabolomics studies, etc. Hence it is essential to use a ... -
Cortical PV and VIP neurons are necessary for texture discrimination performance of freely behaving mice
(2025-03-27)Rodents gather information about their surroundings through their whiskers, enabling them to differentiate textures, recognize objects, and navigate. Each whisker is represented in the barrel cortex (S1BF) by a single ... -
Biochemical Characterization of Otoferlin, the Ca2+ sensor for exocytosis at inner hair cell synapses
(2025-03-27)Transmission of sound from the ear to the brain requires high temporal and spatial fidelity. Inner hair cells (IHC) of the inner ear are the primary sensory organ of hearing, forming the first synapse of the auditory ... -
Structural and biochemical studies on co-transcriptional endonuclease reactions
(2025-03-25)Influenza, an acute respiratory disease, causes 290,000 to 650,000 human deaths annually (Iuliano et al., 2018; WHO, 2023). During an influenza infection, the virus ensures proper handling of viral mRNA, including nuclear ... -
Viscoelastic properties of epithelial cells: 3D structures and composite elements
(2025-03-14)Epithelial cells form complex, polarized layers in the body to cover organs and cavities. While the mechanical properties of single cells and 2D monolayers have been extensively studied, recent research suggests that 3D ... -
Reconstitution and molecular characterisation of the mitochondrial membrane contact site
(2025-03-14)Due to their endosymbiotic origin, mitochondria of eukaryotic cells are enveloped by two membranes. While the outer membrane is rather flat, the inner membrane is intricately folded into subcompartments called cristae. ... -
Bone Morphogenetic Protein signaling in the planarian flatworm Schmidtea mediterranea – evolutionary, cellular, and spatial patterns
(2025-03-13)In early development, morphogen gradients orchestrate the establishment of body axes. Perturbations of such a fundamental process are often damaging to embryonal development, making it difficult to study the role of body ... -
Dynamics and composition of signaling droplets reveal an impact of cellular transport during B cell activation
(2025-03-13)B cell activation during immune responses relies on the signaling network downstream the B cell antigen receptor (BCR). BCRs engaged by an antigen recruit a plethora of signal transducers forming BCR signalosomes, which ... -
Molecular dynamics simulations of ion permeation and gating in potassium channels
(2025-03-13)Potassium (K+) channels are transmembrane ion channels that conduct K+ ions with exceptional selectivity and permeation rates. K+ channels participate in a plethora of important cellular processes, including termination ... -
Fluorescence-lifetime image scanning microscopy
(2025-03-13)Improving optical resolution and image quality has always been an important goal in the field of microscopy. One technique that histori- cally played a major role in the optimization of image quality has been confocal ... -
The Neuropharmacological Basis of Attention in Rhesus Macaques
(2025-03-07)This thesis aimed at unraveling the neuropharmacological basis of attention in rhesus macaques, focusing on the involvement of different neurotransmitter systems. Attention, as a selective filtering process, is crucial ... -
Motor adaptation under visual feedback uncertainty
(2025-03-07)Our motor system continuously receives sensory feedback from our limbs to control movement. This feedback is crucial for compensating for perturbations that disrupt proper control, a process known as motor adaptation. ... -
Uncovering the mode of action of small molecule inhibitors against the RNA polymerase of SARS-CoV-2
(2025-03-07)Severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) is the causative agent of coronavirus disease 2019 (COVID-19). The pandemic has claimed more than 7 million lives since its outbreak at the beginning of 2020, ... -
Sarcomere signaling in a patient-specific iPSC model of hypertrophic cardiomyopathy
(2025-03-07)Hypertrophic cardiomyopathy (HCM) is a severe cardiac disorder associated with ventricular hypertrophy, diastolic dysfunction, and arrhythmias, which can lead to heart failure. Inherited forms of HCM are frequently caused ... -
Constant pH Molecular Dynamics through λ-dynamics
(2025-02-26)This thesis presents a novel implementation of constant pH molecular dynamics simulations using λ-dynamics with Hamiltonian interpolation, enabled by an efficient Fast Multipole Method electrostatic solver. The accuracy ... -
Multisensory integration under visual target uncertainty during planning of reaching movements
(2025-02-25)Movements are fundamental to human interaction and everyday function, relying on the integration of multiple sensory inputs for precise planning and execution. However, sensory uncertainty, particularly in the visual domain, ... -
Thalamic Contributions to Internal Models for Motor Control
