Coherent encoding of subjective spatial position in visual cortex and hippocampus

AB Saleem, EM Diamanti, J Fournier, KD Harris… - Nature, 2018 - nature.com
A major role of vision is to guide navigation, and navigation is strongly driven by vision 1 , 2
, 3 – 4 . Indeed, the brain’s visual and navigational systems are known to interact 5 , 6 , and …

In vitro and in vivo measures of evoked excitatory and inhibitory conductance dynamics in sensory cortices

C Monier, J Fournier, Y Frégnac - Journal of neuroscience methods, 2008 - Elsevier
In order to better understand the synaptic nature of the integration process operated by cortical
neurons during sensory processing, it is necessary to devise quantitative methods which …

Attributable mortality of ICU-acquired bloodstream infections: impact of the source, causative micro-organism, resistance profile and antimicrobial therapy

…, B Berthe, K Mellouk, S Letrou, I Théodose, J Fournier… - Journal of infection, 2017 - Elsevier
Objectives ICU-acquired bloodstream infection (ICUsingle bondBSI) in Intensive Care unit (ICU)

Colonization and infection with extended-spectrum β-lactamase-producing Enterobacteriaceae in ICU patients: what impact on outcomes and carbapenem exposure?

…, D Toledano, E Vantalon, J Fournier… - Journal of …, 2016 - academic.oup.com
Objectives It remains uncertain whether colonization and infection with ESBL-producing
Enterobacteriaceae (ESBL-PE) affect the outcomes for ICU patients. Our objectives were to …

[PDF][PDF] Mouse visual cortex is modulated by distance traveled and by theta oscillations

J Fournier, AB Saleem, EM Diamanti, MJ Wells… - Current Biology, 2020 - cell.com
The visual responses of neurons in the primary visual cortex (V1) are influenced by the animal's
position in the environment [1–5]. V1 responses encode positions that co-fluctuate with …

Continued enteral nutrition until extubation compared with fasting before extubation in patients in the intensive care unit: an open-label, cluster-randomised, parallel …

…, F PHILIPPART, T Marc, J FOURNIER… - The Lancet …, 2023 - thelancet.com
Background Fasting is frequently imposed before extubation in patients in intensive care units,
with the aim to reduce risk of aspiration. This unevaluated practice might delay extubation…

Looking for the roots of cortical sensory computation in three-layered cortices

J Fournier, CM Müller, G Laurent - Current opinion in neurobiology, 2015 - Elsevier
Highlights • We review the recent and less recent literature on mammalian piriform cortex

Adaptation of the simple or complex nature of V1 receptive fields to visual statistics

J Fournier, C Monier, M Pananceau, Y Frégnac - Nature neuroscience, 2011 - nature.com
Receptive fields in primary visual cortex (V1) are categorized as simple or complex, depending
on their spatial selectivity to stimulus contrast polarity. We studied the dependence of this …
