Interrelation between cardiac and brain small-vessel disease: a pilot quantitative PET and MRI study

Bénédicte Marie Maréchal, Ricardo Alberto Corredor Jerez

Background: Small-vessel disease (SVD) plays a crucial role in cardiac and brain ischemia, but little is known about potential interrelation between both. We retrospectively evaluated 370 patients, aiming at assessing the interrelation between cardiac and ...

Cellular, Synaptic and Network Effects of Acetylcholine in the Neocortex

Henry Markram, Srikanth Ramaswamy, Daniel Keller, Cristina Colangelo, Polina Shichkova

The neocortex is densely innervated by basal forebrain (BF) cholinergic neurons. Long-range axons of cholinergic neurons regulate higher-order cognitive function and dysfunction in the neocortex by releasing acetylcholine (ACh). ACh release dynamically rec ...

Feasibility of neurochemically profiling mouse embryonic brain and its development in utero using 1 H MRS at 14.1 T

Hongxia Lei, Sébastien Robert Victor Herzig

We aimed to evaluate the feasibility of neurochemical profiling of embryonic mouse brain developments in utero and to seek potential in vivo evidence of an energy shift in a mitochondrial pyruvate carrier 1 (MPC1) deficient mouse model. C57BL/6 embryonic m ...

The Cortical States of Wakefulness

Sylvain Crochet, James Poulet

Cortical neurons process information on a background of spontaneous, ongoing activity with distinct spatiotemporal profiles defining different cortical states. During wakefulness, cortical states alter constantly in relation to behavioral context, attentio ...

Optogenetic Dissection of the Basal Forebrain Neuromodulatory Control of Cortical Activation, Plasticity, and Cognition

Carl Petersen

The basal forebrain (BF) houses major ascending projections to the entire neocortex that have long been implicated in arousal, learning, and attention. The disruption of the BF has been linked with major neurological disorders, such as coma and Alzheimer's ...

Ferritin H gene deletion in the choroid plexus and forebrain results in hydrocephalus

Patrick Fraering, Claude André Schweizer

Ferritin H, the major iron storage protein, has essential functions in early embryonic development as well as in adult liver and intestine. To address the question whether ferritin H has similarly essential functions in the brain we used the Cre/loxP syste ...

Neural stem cells are increased after loss of β-catenin, but neural progenitors undergo cell death

Jörg Hülsken

Neurons and glia in the central nervous system originate from neural stem and progenitor cells that reside in the ventricular zones. Here we examine the role of beta-catenin in neural stem cell (NSC) regulation in mouse embryos lacking beta-catenin specifi ...

Embryonic substantia nigra grafts in the mesencephalon send neurites to the host striatum in non-human primate after overexpression of GDNF

Patrick Aebischer

In spite of partial success in treating Parkinson's disease by using ectopically placed grafts of dopamine-producing cells, restoration of the original neuroanatomical circuits, if possible, might work better. Previous evidence of normal anatomic projectio ...

Investigating signal integration with canonical correlation analysis of fMRI brain activation data

Kerstin Preuschoff

How the brain integrates signals from specific areas has been a longstanding critical question for neurobiologists. Two recent observations suggest a new approach to fMRI data analysis of this question. First, in many instances, the brain analyzes inputs b ...

Segmentation of Brain Structures in Presence of a Space-Occupying Lesion

Jean-Philippe Thiran, Meritxell Bach Cuadra, Olivier Cuisenaire

Brain deformations induced by space-occupying lesions may result in unpredictable position and shape of functionally important brain structures. The aim of this study is to propose a method for segmentation of brain structures by deformation of a segmented ...
