Modeling spinal locomotor circuits for movements in developing zebrafish

Many spinal circuits dedicated to locomotor control have been identified in the developing zebrafish. How these circuits operate together to generate the various swimming movements during development remains to be clarified. In this study, we iteratively b ...

Data-driven integration of hippocampal CA1 synaptic physiology in silico

Srikanth Ramaswamy, Eilif Benjamin Muller, Michael Reimann, Armando Romani, Michele Migliore, Szabolcs Kali, Sàra Sàray, Audrey Mercer, András Ecker

The anatomy and physiology of monosynaptic connections in rodent hippocampal CA1 have been extensively studied in recent decades. Yet, the resulting knowledge remains disparate and difficult to reconcile. Here, we present a data-driven approach to integrat ...

Mesoscopic population equations for spiking neural networks with synaptic short-term plasticity

Wulfram Gerstner, Valentin Marc Schmutz, Tilo Schwalger

Coarse-graining microscopic models of biological neural networks to obtain mesoscopic models of neural activities is an essential step towards multi-scale models of the brain. Here, we extend a recent theory for mesoscopic population dynamics with static s ...

Dendritic Voltage Recordings Explain Paradoxical Synaptic Plasticity: A Modeling Study

Wulfram Gerstner, Claire Meissner-Bernard, Matthias Chinyen Tsai, 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 ...

Calcium-Mediated Liposome Fusion to Engineer Giant Lipid Vesicles with Cytosolic Proteins and Reconstituted Mammalian Proteins

Leo Scheller

Giant unilamellar lipid vesicles (GUVs) are widely used as model membrane systems and provide an excellent basis to construct artificial cells. To construct more sophisticated artificial cells, proteins-in particular membrane proteins-need to be incorporat ...

The Target of Exuberant Projections in Development

Giorgio Innocenti

In addition to neuronal death and elimination of synapses, the production of transient, exuberant axons, and axonal branches is a general phenomenon in development across species and systems. To understand what drives the decision of which axons are mainta ...

Estimating the Readily-Releasable Vesicle Pool Size at Synaptic Connections in the Neocortex

Henry Markram, Rodrigo de Campos Perin, Srikanth Ramaswamy, Eilif Benjamin Muller, Giuseppe Chindemi, Natali Barros Zulaica

Previous studies based on the 'Quantal Model' for synaptic transmission suggest that neurotransmitter release is mediated by a single release site at individual synaptic contacts in the neocortex. However, recent studies seem to contradict this hypothesis ...

Cellular, Synaptic and Network Effects of Acetylcholine in the Neocortex

Henry Markram, Srikanth Ramaswamy, Daniel Keller, Cristina Colangelo, Polina Shichkova

The neocortex is densely innervated by basal forebrain (BF) cholinergic neurons. Long-range axons of cholinergic neurons regulate higher-order cognitive function and dysfunction in the neocortex by releasing acetylcholine (ACh). ACh release dynamically rec ...

Regulation of adenylyl cyclase 5 in striatal neurons confers the ability to detect coincident neuromodulatory signals

Ursula Röthlisberger, Paolo Carloni, Siri Camee van Keulen, Daniele Narzi

Author summary Adenylyl cyclases (ACs) are enzymes that can translate extracellular signals into the intracellular molecule cAMP, which is thus a 2nd messenger of extracellular events. The brain expresses nine membrane-bound AC variants, and AC5 is the dom ...

Identification of novel PCTAIRE-1/CDK16 substrates using a chemical genetic screen

Maria Deak, Kei Sakamoto, Caterina Collodet

PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK) 16), is a Ser/Thr kinase that has been implicated in many cellular processes, including cell cycle, spermatogenesis, neurite outgrowth, and vesicle trafficking. Most recently, it has been propo ...
