Nutritional Ketosis Increases NAD+/NADH Ratio in Healthy Human Brain: An in Vivo Study by 31P-MRS

Rolf Gruetter, Lijing Xin, Özlem Ipek, Mojgan Masoodi, Nicolas Christinat, Maya Shevlyakova

Ketones represent an important alternative fuel for the brain under glucose hypo-metabolic conditions induced by neurological diseases or aging, however their metabolic consequences in healthy brains remain unclear. Here we report that ketones can increase ...

Distributed Patterns of Brain Activity Underlying Real-Time fMRI Neurofeedback Training

Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Kirsten Emmert, Rotem Roza Kopel

Neurofeedback (NF) based on real-time functional magnetic resonance imaging (rt-fMRI) is an exciting neuroimaging application. In most rt-fMRI NF studies, the activity level of a single region of interest (ROI) is provided as a feedback signal and the part ...

Atlas-Free Connectivity Analysis Driven By White Matter Structure

Luca Dodero

Diffusion tensor imaging allows to infer brain connectivity from white matter, which can then be investigated aiming at finding possible biomarkers of disease. The usual initial step in graph construction is to identify the nodes in the brain using a prede ...

Global tractography with embedded anatomical priors and microstructure information for quantitative connectomics

Alia Lemkaddem

Over the last decades new technologies have shed the light on an improved understanding of brain structure and function. Recently, an imaging modality referred to as diffusion Magnetic Resonance Imaging (dMRI) has emerged. By exploiting the natural motion ...

The topology of structural brain connectivity in diseases and spatio-temporal connectomics

Alessandra Griffa

The brain is a complex system, composed of multiple neural units interconnected at different spatial and temporal scales. Diffusion MRI allows probing in vivo the anatomical connectivity between different cortical areas through white matter tracts. In para ...

Large Volume Imaging of Rodent Brain Anatomy with Emphasis on Selective Plane Illumination Microscopy

Jean Pierre Ghobril

Inside the human brain there are 86 Billion neurons exchanging electrical impulses to allow reaction, homoeostasis and intelligence. Their coarse organization has been described, leaving us with a fair understanding of macrocircuitry. The microcircuitry of ...

Multiphoton microscopy in brain imaging

Graham Knott, Bohumil Maco, Ludovico Silvestri

Brain imaging is becoming an important field in the frame of the neurophotonics in correlations with other medical ones in neuroscience studying functional and morphological aspects. In this presentation an overview on multi photon imaging of the brain wil ...

Dynamic brain networks explored by structure-revealing methods

Nora Leonardi

The human brain is a complex system able to continuously adapt. How and where brain activity is modulated by behavior can be studied with functional magnetic resonance imaging (fMRI), a non-invasive neuroimaging technique with excellent spatial resolution ...
