Immunogold characteristics of VGLUT3-positive GABAergic nerve terminals suggest corelease of glutamate

There is compelling evidence that glutamate can act as a cotransmitter in the mammalian brain. Interestingly, the third vesicular glutamate transporter (VGLUT3) is primarily found in neurons that were anticipated to be nonglutamatergic. Whereas the functio ...

Integration of 2D and 3D Thin Film Glassy Carbon Electrode Arrays for Electrochemical Dopamine Sensing in Flexible Neuroelectronic Implants

Philippe Renaud, André Mercanzini, Jules John Vandersarl

Here we present the development and characterization of a flexible implantable neural probe with glassy carbon electrode arrays. The use of carbon electrodes allows for these devices to be used as chemical sensors, in addition to their typical use as elect ...

The genetics of social hierarchies

Maria del Carmen Sandi Perez, Michael van der Kooij

The organization of individuals in social hierarchies is ubiquitous in social species. Although the evolution of dominance at the population level is constrained by its interactive character, selective breeding shows that dominance and subordination can be ...

Spatiotemporal Brain Dynamics of Emotional Face Processing Modulations Induced by the Serotonin 1A/2A Receptor Agonist Psilocybin

Fosco Bernasconi

Emotional face processing is critically modulated by the serotonergic system. For instance, emotional face processing is impaired by acute psilocybin administration, a serotonin (5-HT) 1A and 2A receptor agonist. However, the spatiotemporal brain mechanism ...

X-ray structure of the mouse serotonin 5-HT3 receptor

Horst Vogel, Henning Paul-Julius Stahlberg, Rudolf Hovius, Cédric Deluz, Luigino Grasso, Romain Wyss, Ghérici Hassaïne, Menno Berend Tol

Neurotransmitter-gated ion channels of the Cys-loop receptor family mediate fast neurotransmission throughout the nervous system. The molecular processes of neurotransmitter binding, subsequent opening of the ion channel and ion permeation remain poorly un ...

Large scale expression and purification of the mouse 5-HT3 receptor

Horst Vogel, Cédric Deluz, Ghérici Hassaïne, Menno Berend Tol

Receptors of the Cys-loop family are central to neurotransmission and primary therapeutic targets. In order to decipher their gating and modulation mechanisms, structural data is essential. However, structural studies require large amounts of pure, functio ...

Peripuberty stress leads to abnormal aggression, altered amygdala and orbitofrontal reactivity and increased prefrontal MAOA gene expression

Pierre Magistretti, Maria del Carmen Sandi Perez, Didier Trono, Maria Isabel Cordero Campana, Guillaume Poirier, Anna Claire Groner, Cristina Marquez Vega

Although adverse early life experiences have been found to increase lifetime risk to develop violent behaviors, the neurobiological mechanisms underlying these long-term effects remain unclear. We present a novel animal model for pathological aggression in ...

A Biochemical and Biophysical Investigation of 5-HT3 Receptor Stability

Menno Berend Tol

The 5-hydroxytryptamine 3 receptor (5-HT3R) is a member of the pentameric ligand-gated ion channel (pLGIC) family, that plays an important role in fast signal transduction and cell-cell communication in synapses: They convert a chemical signal from a neuro ...

Fluoxetine regulates the expression of neurotrophic/growth factors and glucose metabolism in astrocytes

Pierre Magistretti, Jean-Luc Martin, Igor Allaman

RATIONALE: The pharmacological actions of most antidepressants are ascribed to the modulation of serotonergic and/or noradrenergic transmission in the brain. During therapeutic treatment for major depression, fluoxetine, one of the most commonly prescribed ...

MAOA-L carriers are better at making optimal financial decisions under risk

Genes can affect behaviour towards risks through at least two distinct neurocomputational mechanisms: they may affect the value assigned to different risky options, or they may affect the way in which the brain adjudicates between options based on their va ...
