The role of medial amygdala inhibitory neurons in regulating social behavior

Aggression is an evolutionary conserved social behavior that is necessary for an animalÂŽs survival. The neural substrates coordinating aggression are known to exist in the amygdala and the hypothalamus. While the medial amygdala (MeA) and the ventrolatera ...

Distinguishing dopamine and calcium responses using XNA-nanotube sensors for improved neurochemical sensing

Ardemis Anoush Boghossian, Melania Reggente, Alice Judith Gillen, Alessandra Antonucci, Daniel Eduardo Morales Garza

To date, the engineering of single-stranded DNA-SWCNT (DNA-SWCNT) optical biosensors have largely focused on creating sensors for new applications with little focus on optimising existing sensors for in vitro and in vivo conditions. Recent studies have sho ...

A functional model of adult dentate gyrus neurogenesis

Wulfram Gerstner, Olivia Gozel

In adult dentate gyrus neurogenesis, the link between maturation of newborn neurons and their function, such as behavioral pattern separation, has remained puzzling. By analyzing a theoretical model, we show that the switch from excitation to inhibition of ...

A VTA to Basal Amygdala Dopamine Projection Contributes to Signal Salient Somatosensory Events during Fear Learning

Ralf Schneggenburger, Olexiy Kochubey, Wei Tang, Michael Kintscher

The amygdala is a brain area critical for the formation of fear memories. However, the nature of the teaching signal(s) that drive plasticity in the amygdala are still under debate. Here, we use optogenetic methods to investigate the contribution of ventra ...

A brief exposure to rightward prismatic adaptation changes resting-state network characteristics of the ventral attentional system

Patric Hagmann, Stephanie Clarke

A brief session of rightward prismatic adaptation (R-PA) has been shown to alleviate neglect symptoms in patients with right hemispheric damage, very likely by switching hemispheric dominance of the ventral attentional network (VAN) from the right to the l ...

Glutaredoxin 1 Downregulation in the Substantia Nigra Leads to Dopaminergic Degeneration in Mice

Bernard Schneider

Background Parkinson's disease (PD) is characterized by a severe loss of the dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). Perturbation of protein thiol redox homeostasis has been shown to play a role in the dysregulation of cell ...

The glucocorticoid receptor in the nucleus accumbens plays a crucial role in social rank attainment in rodents

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Fiona Hollis, Ioannis Zalachoras, Meltem Weger, Thomas Didier Larrieu, Alexandre Claude Gustave Bacq

Social hierarchy in social species is usually established through competitive encounters with conspecifics. It determines the access to limited resources and, thus, leads to reduced fights among individuals within a group. Despite the known importance of s ...

Excitatory/inhibitory neuronal metabolic balance in mouse hippocampus upon infusion of [U-C-13(6)]glucose

Rolf Gruetter, Hongxia Lei, Bernard Lanz, Carole Poitry-Yamate, Antoine Timothée Cherix, Guillaume Donati, Blanca Lizarbe Serra

Hippocampus plays a critical role in linking brain energetics and behavior typically associated to stress exposure. In this study, we aimed to simultaneously assess excitatory and inhibitory neuronal metabolism in mouse hippocampus in vivo by applying (18) ...

Excitation states of metabolic networks predict dose-response fingerprinting and ligand pulse phase signalling

Pierre Magistretti, Henry Markram, Felix Schürmann, Daniel Keller, Jay Coggan

With a computational model of energy metabolism in an astrocyte, we show how a system of enzymes in a cascade can act as a functional unit of interdependent reactions, rather than merely a series of independent reactions. These systems may exist in multipl ...

Astrocytic release of ATP through type 2 inositol 1,4,5‐trisphosphate receptor calcium signaling and social dominance behavior in mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Marie-Isabelle Guillot de Suduiraut, Fiona Hollis, Eva Ramos Fernandez

Brain mitochondrial function is critical for numerous neuronal processes. We recently identified a link between brain energy and social dominance, where higher levels of mitochondrial function resulted in increased social competitive ability. The underlyin ...
