Transient brain activity disentangles fMRI resting-state dynamics in terms of spatially and temporally overlapping networks

Dimitri Nestor Alice Van De Ville, Fikret Isik Karahanoglu

Dynamics of resting-state functional magnetic resonance imaging (fMRI) provide a new window onto the organizational principles of brain function. Using state-of-the-art signal processing techniques, we extract innovation-driven co-activation patterns (iCAP ...

Multi-modal assessment of long-term erythropoietin treatment after neonatal hypoxic-ischemic injury in rat brain

Rolf Gruetter, Yohan Van de Looij

Erythropoietin (EPO) has been recognized as a neuroprotective agent. In animal models of neonatal brain injury, exogenous EPO has been shown to reduce lesion size, improve structure and function. Experimental studies have focused on short course treatment ...

Lactoferrin during lactation protects the immature hypoxic-ischemic rat brain

Yohan Van de Looij

Objective Lactoferrin (Lf) is an iron-binding glycoprotein secreted in maternal milk presenting anti-inflammatory and antioxidant properties. It shows efficient absorption into the brain from nutritional source. Brain injury frequently resulting from cereb ...

Characterization of sustained BOLD activation in the rat barrel cortex and Neurochemical consequences

Rolf Gruetter, Lijing Xin, Nathalie Just, Hanne Frenkel

To date, only a couple of functional MR spectroscopy (fMRS) studies were conducted in rats. Due to the low temporal resolution of 1H-MRS techniques, prolonged stimulation paradigms are necessary for investigating the metabolic outcome in the rat brain duri ...

Resting-State Functional Connectivity Emerges from Structurally and Dynamically Shaped Slow Linear Fluctuations

Patric Hagmann

Brain fluctuations at rest are not random but are structured in spatial patterns of correlated activity across different brain areas. The question of how resting-state functional connectivity (FC) emerges from the brain's anatomical connections has motivat ...

Thalamic control of cortical states

Carl Petersen, Sylvain Crochet, James Poulet

We investigated the impact of thalamus on ongoing cortical activity in the awake, behaving mouse. We demonstrate that the desynchronized cortical state during active behavior is driven by a centrally generated increase in thalamic action potential firing, ...

Key electrophysiological, molecular, and metabolic signatures of sleep and wakefulness revealed in primary cortical cultures

Johan Auwerx, Richardus Houtkooper, Cyril Mikhail

Although sleep is defined as a behavioral state, at the cortical level sleep has local and use-dependent features suggesting that it is a property of neuronal assemblies requiring sleep in function of the activation experienced during prior wakefulness. He ...

Possible climate change impacts on the hydrological and vegetative character of Everglades National Park, Florida

Andrea Rinaldo

The increasing threat of global climate change is predicted to have immense influences on ecosystems worldwide, but could be particularly severe to vulnerable wetland environments such as the Everglades. This work investigates the impact global climate cha ...

Classifying minimally disabled multiple sclerosis patients from resting state functional connectivity

Dimitri Nestor Alice Van De Ville, Patric Hagmann, Jonas Richiardi

Multiple sclerosis (MS), a variable and diffuse disease affecting white and gray matter, is known to cause functional connectivity anomalies in patients. However, related studies published to-date are post hoc; our hypothesis was that such alterations coul ...

Sleep paralysis in narcolepsy: more than just a motor dissociative phenomenon?

Francesco Manni

Sleep paralyses are viewed as pure motor phenomena featured by a dissociated state in which REM-related muscle atonia coexists with a wakefulness state of full consciousness. We present a 59-year-old man diagnosed with narcolepsy experiencing sleep paralys ...
