Unequal cleavage of the C. elegans zygote ensures robust embryogenesis

Asymmetric cell divisions play key roles in generating cellular diversity during embryogenesis, and in tissue homeostasis during postembryonic life. Particular asymmetric cell divisions producing differentially sized daughter cells were described in many s ...

Probing myelin content of the human brain with MRI: A review

Jean-Philippe Thiran, Tobias Kober, Tom Hilbert, Gian Franco Piredda

Rapid and efficient transmission of electric signals among neurons of vertebrates is ensured by myelin-insulating sheaths surrounding axons. Human cognition, sensation, and motor functions rely on the integrity of these layers, and demyelinating diseases o ...

Neuron Geometry Underlies Universal Network Features in Cortical Microcircuits

Henry Markram, Rodrigo de Campos Perin, Idan Segev, Eyal Gal, Michael London

Why do cortical microcircuits in a variety of brain regions express similar, highly nonrandom, network motifs? To what extent this structure is innate and how much of it is molded by plasticity and learning processes? To address these questions, we develop ...

On the choice of metric in gradient-based theories of brain function

Wulfram Gerstner, Johanni Michael Brea, Jean-Pascal Théodor Pfister

The idea that the brain functions so as to minimize certain costs pervades theoretical neuroscience. Because a cost function by itself does not predict how the brain finds its minima, additional assumptions about the optimization method need to be made to ...

Impacts of thermal mismatches on chytrid fungus Batrachochytrium dendrobatidis prevalence are moderated by life stage, body size, elevation and latitude

Suzanne Marie Young

Global climate change is increasing the frequency of unpredictable weather conditions; however, it remains unclear how species-level and geographic factors, including body size and latitude, moderate impacts of unusually warm or cool temperatures on diseas ...

Gradients of structure-function tethering across neocortex

Patric Hagmann

The white matter architecture of the brain imparts a distinct signature on neuronal coactivation patterns. Interregional projections promote synchrony among distant neuronal populations, giving rise to richly patterned functional networks. A variety of sta ...

Generalized size scaling of metabolic rates based on single-cell measurements with freshwater phytoplankton

Anders Meibom, Andrea Rinaldo, Stéphane Laurent Escrig, Andrea Giometto, Silvia Zaoli, Emilio Marañón, Amos Maritan

Kleiber's law describes the scaling of metabolic rate with body size across several orders of magnitude in size and across taxa and is widely regarded as a fundamental law in biology. The physiological origins of Kleiber's law are still debated and general ...

Male competition and the evolution of mating and ire-history traits in experimental populations of Aedes aegypti

Brian Dennis Hollis

Aedes aegypti is an important disease vector and a major target of reproductive control efforts. We manipulated the opportunity for sexual selection in populations of Ae. aegypti by controlling the number of males competing for a single female. Populations ...

Longitudinal study of neonatal brain tissue volumes in preterm infants and their ability to predict neurodevelopmental outcome

Djalel Eddine Meskaldji, Laura Ioana Gui, Serafeim Loukas

Premature birth has been associated with poor neurodevelopmental outcomes. However, the relation between such outcomes and brain growth in the neonatal period has not yet been fully elucidated. This study investigates longitudinal brain development between ...

Whole brain measurements of the positive BOLD response variability during a finger tapping task at 7 T show regional differences in its profiles

Wietske Van der Zwaag, Yohan Boillat

PURPOSE: The positive BOLD response can vary across brain regions. Here, the positive BOLD responses of motor regions, including the cerebellum, were investigated by fast fMRI acquisition. METHODS: The participants were asked to perform an event-related fi ...
