Optimal Control of Transient Dynamics in Balanced Networks Supports Generation of Complex Movements
Wulfram Gerstner, Tim Vogels, Guillaume Hennequin
Populations of neurons in motor cortex engage in complex transient dynamics of large amplitude during the execution of limb movements. Traditional network models with stochastically assigned synapses cannot reproduce this behavior. Here we introduce a clas ...
Cell Press2014Dielectric pads and low- B1+ adiabatic pulses: Complementary techniques to optimize structural T1w whole-brain MP2RAGE scans at 7 tesla
Tobias Kober, José Pedro Rebelo Ferreira Marques, Kieran O'Brien, François Lazeyras
Purpose To evaluate the combination of low-B1+ adiabatic pulses and high permittivity (εr ≈ 165) dielectric pads effectiveness to reproducibly improve the inversion efficiency for whole-brain MP2RAGE scans, at ultra-high field. Materials and Methods Two lo ...
Wiley-Blackwell2014The In-Silico Neocortical Microcircuit
The neocortex is one of the most important brain regions, occupying more than 80% of the brain volume in mammals and contributing massively to its capability of perceiving and interpreting then environment. While it has been extensively studied, it is stil ...
EPFL2014Fluctuations and information filtering in coupled populations of spiking neurons with adaptation
Wulfram Gerstner, Tilo Schwalger, Richard Naud, Moritz Deger
Finite-sized populations of spiking elements are fundamental to brain function but also are used in many areas of physics. Here we present a theory of the dynamics of finite-sized populations of spiking units, based on a quasirenewal description of neurons ...
2014Multivariate Pattern Recognition for Diagnosis and Prognosis in Clinical Neuroimaging: State of the Art, Current Challenges and Future Trends
Dimitri Nestor Alice Van De Ville
Many diseases are associated with systematic modifications in brain morphometry and function. These alterations may be subtle, in particular at early stages of the disease progress, and thus not evident by visual inspection alone. Group-level statistical c ...
Springer Verlag2014Brain Connections Associated With Socio-Cognitive Skills in Preterm and Low Birth Weight School Age Children
Jean-Philippe Thiran, Elda Fischi Gomez, Patric Hagmann, Djalel Eddine Meskaldji, François Lazeyras
Identification of neuroimaging biomarkers following extreme prematurity (EP) and intrauterine growth restriction (IUGR) is crucial for understanding their cognitive and behavioral impairments at school age ...
2014Lateralization of the primary auditory cortex, in patients with unilateral tinnitus
Melissa Saenz, Wietske Van der Zwaag, Naghmeh Ghazaleh
Tinnitus, the chronic perception of ringing or other phantom sounds, is typically associated with hearing loss. The reduction of auditory input that conveys to auditory cortex leads to the changes in the balance of excitatory and inhibitory activation of t ...
2014(Un)awareness of unilateral spatial neglect: A quantitative evaluation of performance in visuo-spatial tasks
Roberta Ronchi, Giuseppe Vallar
Right-brain-damaged patients with unilateral spatial neglect are usually unaware (anosognosic) about their spatial deficits. However, in the scientific literature there is a lack of systematic and quantitative evaluation of this kind of unawareness, despit ...
Elsevier Masson2014Multi-scale integration and predictability in resting state brain activity
Alessandra Griffa, Patric Hagmann
The human brain displays heterogeneous organization in both structure and function. Here we develop a method to characterize brain regions and networks in terms of information-theoretic measures. We look at how these measures scale when larger spatial regi ...
2014Neurotechnology for Brain Repair
Neurotechnology is the application of scientific knowledge to the practical purpose of understanding, interacting and/or repairing the brain or, in a broader sense, the nervous system. The development of novel approaches to decode functional information fr ...
