The autism susceptibility kinase, TAOK2, phosphorylates eEF2 and modulates translation

Nagammal Neelagandan

Genes implicated in translation control have been associated with autism spectrum disorders (ASDs). However, some important genetic causes of autism, including the 16p11.2 microdeletion, bear no obvious connection to translation. Here, we use proteomics, g ...

Agency Deficits in a Human Genetic Model of Schizophrenia: Insights From 22q11DS Patients

Olaf Blanke, Roy Salomon, Maude Schneider, Nathan Quentin Faivre, Oliver Alan Kannape, Mariia Kaliuzhna, Henrique Galvan Debarba

Schizophrenia is a chronic and disabling mental illness characterized by a disordered sense of self. Current theories suggest that deficiencies in the sense of control over one’s actions (Sense of Agency, SoA) may underlie some of the symptoms of schizophr ...

The critical periods of cerebral plasticity: A key aspect in a dialog between psychoanalysis and neuroscience centered on the psychopathology of schizophrenia

Pierre Magistretti

Through research into the molecular and cellular mechanisms that occur during critical periods, recent experimental neurobiological data have brought to light the importance of early childhood. These have demonstrated that childhood and early environmental ...

Lactate supply overtakes glucose when neural computational and cognitive loads scale up

Pierre Magistretti

Neural computational power is determined by neuroenergetics, but how and which energy substrates are allocated to various forms of memory engram is unclear. To solve this question, we asked whether neuronal fueling by glucose or lactate scales differently ...

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 ...

Extensive and diverse patterns of cell death sculpt neural networks in insects

Pavan P Ramdya, Chin-Lin Chen

Changes to the structure and function of neural networks are thought to underlie the evolutionary adaptation of animal behaviours. Among the many developmental phenomena that generate change programmed cell death (PCD) appears to play a key role. We show t ...

From adult dentate gyrus neurogenesis to pattern separation

Olivia Gozel

For a few decades, adult dentate gyrus neurogenesis has been widely recognized by the neuroscience community as an intriguing phenomenon. Two observations are particularly puzzling. At the cellular level, the switch from excitation to inhibition of the GAB ...

Fast and robust estimation of NODDI parameters using non-Gaussian noise models and spatial regularization

Jean-Philippe Thiran, Alessandro Daducci, Erick Jorge Canales Rodriguez

In this study, we developed a robust inversion algorithm to estimate the Neurite Orientation Dispersion and Density Imaging (NODDI) model. It is based on the Accelerated Microstructure Imaging via Convex Optimization (AMICO) framework. However, in contrast ...

Towards a supervised classification of neocortical interneuron morphologies

Sean Lewis Hill

BackgroundThe challenge of classifying cortical interneurons is yet to be solved. Data-driven classification into established morphological types may provide insight and practical value.ResultsWe trained models using 217 high-quality morphologies of rat so ...

Notch2 Signaling Maintains NSC Quiescence in the Murine Ventricular-Subventricular Zone

Freddy Radtke

Neurogenesis continues in the ventricular-subventricular zone (V-SVZ) of the adult forebrain from quiescent neural stem cells (NSCs). V-SVZ NSCs are a reservoir for new olfactory bulb (OB) neurons that migrate through the rostral migratory stream (RMS). To ...

Parkin mediates the ubiquitination of VPS35 and modulates retromer-dependent endosomal sorting

Liliane Glauser, Elpida Tsika

Mutations in a number of genes cause familial forms of Parkinson's disease (PD), including mutations in the vacuolar protein sorting 35 ortholog (VPS35) and parkin genes. In this study, we identify a novel functional interaction between parkin and VPS35. W ...

Structural and functional brain imaging using extended-focus optical coherence tomography and microscopy

Paul James Marchand

Neuroimaging techniques aim at revealing the anatomy and functional organisation of cerebral structures. Over the past decades, functional magnetic resonance imaging (fMRI) has revolutionized our understanding of human cerebral physiology through its abili ...

Multilayer 3D electrodes for neural implants

Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Paola Vagni

Objective. In many applications, multielectrode arrays employed as neural implants require a high density and a high number of electrodes to precisely record and stimulate the activity of the nervous system while preserving the overall size of the array as ...

Diamond microelectrode arrays for in vitro neuronal recordings

Michele Giugliano

A novel microfabrication technique for microelectrode arrays (MEAs) with a full diamond-cell interface is demonstrated. Boron-doped nano-crystalline diamond (BNCD) is used as a conductive electrode material on metal tracks insulated by intrinsic NCD. MEAs ...

An organotypic slice culture to study the formation of calyx of Held synapses in-vitro

Ralf Schneggenburger, Elin Kristina Kronander

The calyx of Held, a large axo-somatic relay synapse containing hundreds of presynaptic active zones, is possibly the largest nerve terminal in the mammalian CNS. Studying its initial growth in-vitro might provide insights into the specification of synapti ...

Cortical neurons gradually attain a post-mitotic state

Johannes Gräff

Once generated, neurons are thought to permanently exit the cell cycle and become irreversibly differentiated. However, neither the precise point at which this post-mitotic state is attained nor the extent of its irreversibility is clearly defined. Here we ...

Cell-type specific function of GABAergic neurons in layers 2 and 3 of mouse barrel cortex

Carl Petersen

GABAergic neurons are a minor fraction of the neocortical neuronal population, but they are highly diverse in their features. The GABAergic neurons can be divided into three largely non-overlapping groups, defined through the expression of ionotropic serot ...
