From self-assessment to frustration, a small step toward autonomy in robotic navigation.

Frontiers in neurorobotics

Jauffret A, Cuperlier N, Tarroux P, Gaussier P.
PMID: 24115931
Front Neurorobot. 2013 Oct 08;7:16. doi: 10.3389/fnbot.2013.00016. eCollection 2013.

Autonomy and self-improvement capabilities are still challenging in the fields of robotics and machine learning. Allowing a robot to autonomously navigate in wide and unknown environments not only requires a repertoire of robust strategies to cope with miscellaneous situations,...

Shrinkage estimation of long-term water ingestion rates.

Journal of exposure science & environmental epidemiology

Cuvelier N, Bartell SM.
PMID: 33603092
J Expo Sci Environ Epidemiol. 2021 Nov;31(6):990-998. doi: 10.1038/s41370-021-00300-0. Epub 2021 Feb 18.

BACKGROUND: Water consumption is a necessity for human life, though it also presents an opportunity for exposure to harmful chemicals and toxins. In order to gain a better understanding of the potential levels of chronic exposure, accurate estimates of...

Context-dependent modulation of aggressiveness of pediatric tumors by individual oncogenic RAS isoforms.

Oncogene

Bauer J, Cuvelier N, Ragab N, Simon-Keller K, Nitzki F, Geyer N, Botermann DS, Elmer DP, Rosenberger A, Rando TA, Biressi S, Fagin JA, Saur D, Dullin C, Schildhaus HU, Schulz-Schaeffer W, Aberger F, Uhmann A, Hahn H.
PMID: 34172934
Oncogene. 2021 Aug;40(31):4955-4966. doi: 10.1038/s41388-021-01904-4. Epub 2021 Jun 25.

A prototypic pediatric cancer that frequently shows activation of RAS signaling is embryonal rhabdomyosarcoma (ERMS). ERMS also show aberrant Hedgehog (HH)/GLI signaling activity and can be driven by germline mutations in this pathway. We show, that in ERMS cell...

From grid cells and visual place cells to multimodal place cell: a new robotic architecture.

Frontiers in neurorobotics

Jauffret A, Cuperlier N, Gaussier P.
PMID: 25904862
Front Neurorobot. 2015 Apr 07;9:1. doi: 10.3389/fnbot.2015.00001. eCollection 2015.

In the present study, a new architecture for the generation of grid cells (GC) was implemented on a real robot. In order to test this model a simple place cell (PC) model merging visual PC activity and GC was...

Hippocampal and Cortical Pyramidal Neurons Swell in Parallel with Astrocytes during Acute Hypoosmolar Stress.

Frontiers in cellular neuroscience

Murphy TR, Davila D, Cuvelier N, Young LR, Lauderdale K, Binder DK, Fiacco TA.
PMID: 28979186
Front Cell Neurosci. 2017 Sep 20;11:275. doi: 10.3389/fncel.2017.00275. eCollection 2017.

Normal nervous system function is critically dependent on the balance of water and ions in the extracellular space (ECS). Pathological reduction in brain interstitial osmolarity results in osmotically-driven flux of water into cells, causing cellular edema which reduces the...

Time as the fourth dimension in the hippocampus.

Progress in neurobiology

Banquet JP, Gaussier P, Cuperlier N, Hok V, Save E, Poucet B, Quoy M, Wiener SI.
PMID: 33053416
Prog Neurobiol. 2021 Apr;199:101920. doi: 10.1016/j.pneurobio.2020.101920. Epub 2020 Oct 12.

Experiences of animal and human beings are structured by the continuity of space and time coupled with the uni-directionality of time. In addition to its pivotal position in spatial processing and navigation, the hippocampal system also plays a central,...

Hedgehog Inhibitors in Rhabdomyosarcoma: A Comparison of Four Compounds and Responsiveness of Four Cell Lines.

Frontiers in oncology

Ridzewski R, Rettberg D, Dittmann K, Cuvelier N, Fulda S, Hahn H.
PMID: 26106586
Front Oncol. 2015 Jun 08;5:130. doi: 10.3389/fonc.2015.00130. eCollection 2015.

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children and is divided into two major histological subgroups, i.e., embryonal (ERMS) and alveolar RMS (ARMS). RMS can show HEDGEHOG/SMOOTHENED (HH/SMO) signaling activity and several clinical trials using HH...

Oncogenic RAS Mutants Confer Resistance of RMS13 Rhabdomyosarcoma Cells to Oxidative Stress-Induced Ferroptotic Cell Death.

Frontiers in oncology

Front Oncol. 2015 Jun 22;5:131. doi: 10.3389/fonc.2015.00131. eCollection 2015.

Recent genomic studies revealed a high rate of recurrent mutations in the RAS pathway in primary rhabdomyosarcoma (RMS) samples. In the present study, we therefore investigated how oncogenic RAS mutants impinge on the regulation of cell death of RMS13...
