Dynamic Imaging of Lipid Membranes by Means of Water

Orly Bagunu Tarun

Lipid membranes are self-assembled structures whose composition determines the properties of membranes of cells and organelles. The molecular level understanding of lipid membranes is based on spectroscopy and MD simulations of lipid monolayer systems. As ...

Upper stimulation threshold for retinal ganglion cell activation

Diego Ghezzi

Objective. The existence of an upper threshold in electrically stimulated retinal ganglion cells (RGCs) is of interest because of its relevance to the development of visual prosthetic devices, which are designed to restore partial sight to blind patients. ...

Nonlinear microscopy for temporally and spatially resolved label-free imaging of living cells

Marie Eve Pascale Didier

The human brain consists of approximately a hundred billion of neurons that communicate through a unique series of biochemical and electrical processes. When neuronal networks are solicited, electrochemical processes happen involving millions of cells with ...

Membrane water for probing neuronal membrane potentials and ionic fluxes at the single cell level

Pierre Magistretti, Sylvie Roke, Orly Bagunu Tarun, Pascal Jourdain, Marie Eve Pascale Didier

Neurons communicate through electrochemical signaling within a complex network. These signals are composed of changes in membrane potentials and are traditionally measured with the aid of (toxic) fluorescent labels or invasive electrical probes. Here, we d ...

Electrochemical Dynamics of a Single Platinum Nanoparticle Collision Event for the Hydrogen Evolution Reaction

Pekka Eero Peljo, Haiqiang Deng

Chronoamperometry was used to study the dynamics of Pt nanoparticle (NP) collision with an inert ultramicroelectrode via electrocatalytic amplification (ECA) towards hydrogen evolution reaction. First, ECA and dynamic light scattering (DLS) results reveal ...

A microfabricated nerve-on-a-chip platform for rapid assessment of neural conduction in explanted peripheral nerve fibers

Stéphanie Lacour, Diego Ghezzi, Sandra Gribi

Peripheral nerves are anisotropic and heterogeneous neural tissues. Their complex physiology restricts realistic in vitro models, and high resolution and selective probing of axonal activity. Here, we present a nerve-on-a-chip platform that enables rapid e ...

Morphological Diversity Strongly Constrains Synaptic Connectivity and Plasticity

Henry Markram, Eilif Benjamin Muller, Srikanth Ramaswamy, Michael Reimann

Synaptic connectivity between neurons is naturally constrained by the anatomical overlap of neuronal arbors, the space on the axon available for synapses, and by physiological mechanisms that form synapses at a subset of potential synapse locations. What i ...

Layer-Dependent Short-Term Synaptic Plasticity Between Excitatory Neurons in the C2 Barrel Column of Mouse Primary Somatosensory Cortex

Carl Petersen, Sandrine Lefort

Neurons process information through spatiotemporal integration of synaptic input. Synaptic transmission between any given pair of neurons is typically a dynamic process with presynaptic action potentials (APs) evoking depressing or facilitating postsynapti ...

Using the Green's function to simplify and understand dendrites

Willem Anna Mark Wybo

Neurons are endowed with dendrites: tree-like structures that collect and transform inputs. These arborizations are believed to substantially enhance the computational repertoire of neurons. While it has long been known that dendrites are not iso-potential ...
