Cortical cell assemblies and their underlying connectivity: An in silico study

Michael Reimann, András Ecker, Sirio Bolaños Puchet, James Bryden Isbister, Daniela Egas Santander

Recent developments in experimental techniques have enabled simultaneous recordings from thousands of neurons, enabling the study of functional cell assemblies. However, determining the patterns of synaptic connectivity giving rise to these assemblies rema ...

A method to establish functional vagus nerve topography from electro-neurographic spontaneous activity

Silvestro Micera, Simone Romeni

Bioelectronic medicine is an emerging approach to treat many types of diseases via electrical stimulation of the autonomic nervous system (ANS). Because the vagus nerve (VN) is one of the most important nerves controlling several ANS functions, stimulation ...

Approaches to Test the Neurotoxicity of Environmental Contaminants in the Zebrafish Model: From Behavior to Molecular Mechanisms

Anze Zupanic, Colette vom Berg

The occurrence of neuroactive chemicals in the aquatic environment is on the rise and poses a potential threat to aquatic biota of currently unpredictable outcome. In particular, subtle changes caused by these chemicals to an organism's sensation or behavi ...

Excitatory/inhibitory neuronal metabolic balance in mouse hippocampus upon infusion of [U-C-13(6)]glucose

Rolf Gruetter, Hongxia Lei, Bernard Lanz, Carole Poitry-Yamate, Antoine Timothée Cherix, Guillaume Donati, Blanca Lizarbe Serra

Hippocampus plays a critical role in linking brain energetics and behavior typically associated to stress exposure. In this study, we aimed to simultaneously assess excitatory and inhibitory neuronal metabolism in mouse hippocampus in vivo by applying (18) ...

Axon morphology is modulated by the local environment and impacts the noninvasive investigation of its structure-function relationship

Jean-Philippe Thiran, Tim Bjørn Dyrby

Axonal conduction velocity, which ensures efficient function of the brain network, is related to axon diameter. Noninvasive, in vivo axon diameter estimates can be made with diffusion magnetic resonance imaging, but the technique requires three-dimensional ...

Axon regeneration and circuit reorganization after complete spinal cord injury

Sabry Leonardo Barlatey

First human trials involving neuroprosthetic rehabilitation demonstrated recently that significant functional benefits can be achieved with lumbosacral neuromodulation and reorganized spared projections. However, complete spinal cord injuries (SCI) wholly ...

Mapping of real-time morphological changes in the neuronal cytoskeleton with label-free wide-field second-harmonic imaging: a case study of nocodazole

Sylvie Roke, Carlos Alberto Macias Romero, Pascal Jourdain, Marie Eve Pascale Didier, Claire Jacqueline Léa Teulon

We demonstrate the use of wide-field high-throughput second-harmonic (SH) microscopy for investigating cytoskeletal morphological changes on the single-cell level. The method allows for real-time, in vitro, label-free measurements of cytoskeletal changes t ...

Influence of Minor Cr-Additions to the Growth of Columnar Dendrites in Al-Zn Alloys: Influence of Icosahedral Short Range Order in the Liquid

Michel Rappaz, Güven Kurtuldu

The effect of minute Cr additions on dendritic growth directions in Al-20 wt pct Zn alloy has been investigated. As first evidenced by Gonzales and Rappaz (Metall Mater Trans A 37:2797-2806, 2006) Al-Zn alloys exhibit a Dendrite Orientation Transition (DOT ...

Capacitive-like photovoltaic epiretinal stimulation enhances and narrows the network-mediated activity of retinal ganglion cells by recruiting the lateral inhibitory network

Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Naïg Aurelia Ludmilla Chenais

Photovoltaic retinal prostheses theoretically offer the possibility of a standalone high-resolution electrical stimulation of the retina. However, achieving focused epiretinal stimulation is particularly challenging, because of axonal activation and electr ...
