Melanin and Neurotransmitter Signalling Genes Are Differentially Co-Expressed in Growing Feathers of White and Rufous Barn Owls

Nicolas Jean Philippe Guex, Christian Iseli

Regulation of melanin-based pigmentation is complex, involving multiple genes. Because different genes can contribute to the same pigmentation phenotype, the genes identified in model organisms may not necessarily apply to wild species. In the barn owl (Ty ...

Statistical learning quantifies transposable element-mediated cis-regulation

Didier Trono, Julien Léonard Duc, Evaristo Jose Planet Letschert, Alexandre Coudray, Cyril David Son-Tuyên Pulver, Raphaël Gérard Théodore Michel Marie de Deloÿe et Fourcade de Fondeville, Julien Paul André Pontis, Delphine Yvette L Grun, Shaoline Sheppard

Background: Transposable elements (TEs) have colonized the genomes of most metazoans, and many TE-embedded sequences function as cis-regulatory elements (CREs) for genes involved in a wide range of biological processes from early embryo- genesis to innate ...

NMDA-driven dendritic modulation enables multitask representation learning in hierarchical sensory processing pathways

Willem Anna Mark Wybo, Bernd Albert Illing

While sensory representations in the brain depend on context, it remains unclear how such modulations are implemented at the biophysical level, and how processing layers further in the hierarchy can extract useful features for each possible contex-tual sta ...

Intact Drosophila central nervous system cellular quantitation reveals sexual dimorphism

Kathryn Hess Bellwald, Evelyne Ruchti, Ying Shi, Brian Donal McCabe, Wei Jiao, Soumya Banerjee, Gard Spreemann, Samuel William Vernon

Establishing with precision the quantity and identity of the cell types of the brain is a prerequisite for a detailed compendium of gene and protein expression in the central nervous system (CNS). Currently, however, strict quantitation of cell numbers has ...

Emerging principles of spacetime in brains: Meeting report on spatial neurodynamics

Carl Petersen

How do neurons and networks of neurons interact spatially? Here, we overview recent discoveries revealing how spatial dynamics of spiking and postsynaptic activity efficiently expose and explain fundamental brain and brainstem mechanisms behind detection, ...

Diverse cell-specific patterns of alternative polyadenylation in Drosophila

Bart Deplancke

Most genes in higher eukaryotes express isoforms with distinct 3' untranslated regions (3' UTRs), generated by alternative polyadenylation (APA). Since 3' UTRs are predominant locations of post-transcriptional regulation, APA can render such programs condi ...

Miniature neurotransmission is required to maintain Drosophila synaptic structures during ageing

Olivier Burri, Evelyne Ruchti, Brian Donal McCabe, Wei Jiao, Soumya Banerjee, Samuel William Vernon

The decline of neuronal synapses is an established feature of ageing accompanied by the diminishment of neuronal function, and in the motor system at least, a reduction of behavioural capacity. Here, we have investigated Drosophila motor neuron synaptic te ...

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) ...

A computational biophysical model of thalamic and reticular nucleus microcircuitry: from neurons to emergent network dynamics

Elisabetta Iavarone

The thalamus, once believed to be a simple relay station between the body periphery and the neocortex, has started to be recognized as a key player in higher-order functions, such as attention. It participates in the transition between brain states, such a ...

In Vivo Pre-Instructed HSCs Robustly Execute Asymmetric Cell Divisions In Vitro

Matthias Lütolf, Mukul Girotra, Aline Roch, Vincent Trachsel

Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. Under homeostasis, HSCs in their native bone marrow niches are believed to undergo asymmetric cell divisions (ACDs), with one daughter cell maintaining HSC ...
