New Technologies for Nanobiosensing and their Applications to Real-Time Monitoring

Giovanni De Micheli, Sandro Carrara, Cristina Boero

Amperometric biosensors are complex systems and they require a combination of technologies for their development. The aim of the present work is to exploit existing technologies for new purposes in order to develop nanostructured biosensors for the real-ti ...

Formation of the Long Range Dpp Morphogen Gradient

Sascha Dalessi, Markus Affolter

The TGF-β homolog Decapentaplegic (Dpp) acts as a secreted morphogen in the Drosophila wing disc, and spreads through the target tissue in order to form a long range concentration gradient. Despite extensive studies, the mechanism by which the Dpp gradient ...

Cell death detection and ionic homeostasis monitoring with digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Nicolas Pavillon, Pierre Marquet, Jonas Kühn, Pascal Jourdain

Digital holographic microscopy is an interferometric technique enabling the measurement of the quantitative phase shifts induced by cell bodies. We correlate the phase signal measured on neurons with calcium imaging measured by fluorescence on cells loaded ...

Models of neocortical layer 5b pyramidal cells capturing a wide range of dendritic and perisomatic active properties

Henry Markram, Felix Schürmann, Sean Lewis Hill, Idan Segev

The thick-tufted layer 5b pyramidal cell extends its dendritic tree to all six layers of the mammalian neocortex and serves as a major building block for the cortical column. L5b pyramidal cells have been the subject of extensive experimental and modeling ...

Semisynthetic Fluorescent Sensor Proteins Based on Self-Labeling Protein Tags

Matthias Albert Brun

Genetically encoded fluorescent sensor proteins offer the possibility to probe the concentration of key metabolites in living cells. The approaches currently used to generate such fluorescent sensor proteins lack generality, as they require a protein that ...

Complementary Function and Integrated Wiring of the Evolutionarily Distinct Drosophila Olfactory Subsystems

Pavan P Ramdya

To sense myriad environmental odors, animals have evolved multiple, large families of divergent olfactory receptors. How and why distinct receptor repertoires and their associated circuits are functionally and anatomically integrated is essentially unknown ...

Inhibitory Plasticity Balances Excitation and Inhibition in Sensory Pathways and Memory Networks

Wulfram Gerstner, Friedemann Zenke, Claudia Clopath, Tim Vogels

Cortical neurons receive balanced excitatory and inhibitory synaptic currents. Such a balance could be established and maintained in an experience-dependent manner by synaptic plasticity at inhibitory synapses. We show that this mechanism provides an expla ...

Regulation of transmitter release by Ca2+ and synaptotagmin: insights from a large CNS synapse

Ralf Schneggenburger, Olexiy Kochubey

Transmitter release at synapses is driven by elevated intracellular Ca2+ concentration (Ca2+) near the sites of vesicle fusion. Ca2+ signals of profoundly different amplitude and kinetics drive the phasic release component during a presynaptic ac ...

Multiple extra-synaptic spillover mechanisms regulate prolonged activity in cerebellar Golgi cell - granule cell loops

Peter Van der Wal, Olivier Frey

Despite a wealth of in vitro and modelling studies it remains unclear how neuronal populations in the cerebellum interact in vivo. We address the issue of how the cerebellar input layer processes sensory information, with particular focus on the granule ce ...

Network Self-organization explains the distribution of synaptic efficacies in neocortex

Christos Dimitrakakis

The distribution of synaptic efficacies in neocortex has an approximately lognormal shape. Many weak synaptic connections coexist with few very strong connections such that only 20% of synapses contribute 50% of total synaptic strength. Furthermore, recent ...
