Homeostatic regulation of axonal Kv1.1 channels accounts for both synaptic and intrinsic modifications in the hippocampal CA3 circuit

Mickael Maurice Zbili

Homeostatic plasticity of intrinsic excitability goes hand in hand with homeostatic plasticity of synaptic transmission. However, the mechanisms linking the two forms of homeostatic regulation have not been identified so far. Using electrophysiological, im ...

Miniature neurotransmission is required to maintain Drosophila synaptic structures during ageing

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

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 ...

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 ...

Dendritic Voltage Recordings Explain Paradoxical Synaptic Plasticity: A Modeling Study

Wulfram Gerstner, Matthias Chinyen Tsai, Claire Meissner-Bernard, Laureline Logiaco

Experiments have shown that the same stimulation pattern that causes Long-Term Potentiation in proximal synapses, will induce Long-Term Depression in distal ones. In order to understand these, and other, surprising observations we use a phenomenological mo ...

Volcano-Shaped Scanning Probe Microscopy Probe for Combined Force-Electrogram Recordings from Excitable Cells

Philippe Renaud, Georg Fantner, Arnaud Bertsch, Mélanie Thérèse Marie Hannebelle, Benoît Xavier Emmanuel Desbiolles

Atomic force microscopy based approaches have led to remarkable advances in the field of mechanobiology. However, linking the mechanical cues to biological responses requires complementary techniques capable of recording these physiological characteristics ...

Somatostatin enhances visual processing and perception by suppressing excitatory inputs to parvalbumin-positive interneurons in V1

Carl Petersen, Graham Knott, Catherine Maclachlan, Seung-Hee Lee

Somatostatin (SST) is a neuropeptide expressed in a major subtype of GABAergic interneurons in the cortex. Despite abundant expression of SST and its receptors, their modulatory function in cortical processing remains unclear. Here, we found that SST appli ...

Intracellular recording of cardiomyocyte action potentials with nanopatterned volcano-shaped microelectrodes

Benoît Xavier Emmanuel Desbiolles

Micro-nanotechnology based multielectrode arrays have led to remarkable progress in the field of transmembrane voltage recordings of excitable cells. However, electrode geometries alone have failed to produce a cell-electrode interface that is sufficiently ...

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) ...
