[HTML][HTML] Functional maps of neocortical local circuitry

AM Thomson, C Lamy - Frontiers in neuroscience, 2007 - frontiersin.org
This review aims to summarize data obtained with different techniques to provide a functional
map of the local circuit connections made by neocortical neurones, a reference for those …

Repeated exposure to water avoidance stress in rats: a new model for sustained visceral hyperalgesia

…, I Schwetz, HS Ennes, CMR Lamy… - American Journal …, 2005 - journals.physiology.org
Chronic stress plays an important role in the development and exacerbation of symptoms in
functional gastrointestinal disorders. To better understand the mechanisms underlying this …

Astrocytes mediate the effect of oxytocin in the central amygdala on neuronal activity and affective states in rodents

…, J Siemens, Y Goumon, B Boutrel, CM Lamy… - Nature …, 2021 - nature.com
Oxytocin (OT) orchestrates social and emotional behaviors through modulation of neural
circuits. In the central amygdala, the release of OT modulates inhibitory circuits and, thereby, …

[PDF][PDF] Hypoglycemia-activated GLUT2 neurons of the nucleus tractus solitarius stimulate vagal activity and glucagon secretion

CM Lamy, H Sanno, G Labouèbe, A Picard, C Magnan… - Cell metabolism, 2014 - cell.com
Glucose-sensing neurons in the brainstem participate in the regulation of energy homeostasis
but have been poorly characterized because of the lack of specific markers to identify them…

Corticotropin-releasing factor increases GABA synaptic activity and induces inward current in 5-hydroxytryptamine dorsal raphe neurons

…, JC Lemos, JD Nunan, C Lamy… - Journal of …, 2008 - Soc Neuroscience
Stress-related psychiatric disorders such as anxiety and depression involve dysfunction of the
serotonin [5-hydroxytryptamine (5-HT)] system. Previous studies have found that the stress …

Glucagon-like peptide 1 and its analogs act in the dorsal raphe and modulate central serotonin to reduce appetite and body weight

…, F Reimann, I Wernstedt Asterholm, CM Lamy… - Diabetes, 2017 - Am Diabetes Assoc
Glucagon-like peptide 1 (GLP-1) and serotonin play critical roles in energy balance regulation.
Both systems are exploited clinically as antiobesity strategies. Surprisingly, whether they …

[PDF][PDF] Injured axons instruct Schwann cells to build constricting actin spheres to accelerate axonal disintegration

…, L Falquet, L Bartesaghi, R Chrast, CM Lamy… - Cell Reports, 2019 - cell.com
After a peripheral nerve lesion, distal ends of injured axons disintegrate into small fragments
that are subsequently cleared by Schwann cells and later by macrophages. Axonal debris …

Optical probing of sodium dynamics in neurons and astrocytes

CM Lamy, JY Chatton - Neuroimage, 2011 - Elsevier
Changes in intracellular Na + concentration underlie essential neurobiological processes,
but few reliable tools exist for their measurement. Here we characterize a new synthetic Na + -…

Sodium sensing in neurons with a dendrimer-based nanoprobe

CM Lamy, O Sallin, C Loussert, JY Chatton - Acs Nano, 2012 - ACS Publications
Ion imaging is a powerful methodology to assess fundamental biological processes in live
cells. The limited efficiency of some ion-sensing probes and their fast leakage from cells are …
