Epigenetic memory aids: Synaptic and molecular effects of HDAC inhibition that support memory formation

Learning and memory rely on synaptic communication in which intracellular signals are transported to the nucleus to stimulate transcriptional activation. Memory induced transcriptional increases are accompanied by alterations to the epigenetic landscape an ...

The functional characterization of callosal connections

Giorgio Innocenti, Muhamed Barakovic

The brain operates through the synaptic interaction of distant neurons within flexible, often heterogeneous, distributed systems. Histological studies have detailed the connections between distant neurons, but their functional characterization deserves fur ...

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 ...

Wnt5a promotes hippocampal postsynaptic development and GluN2B-induced expression via the eIF2 alpha HRI kinase

Eva Ramos Fernandez

Wnt signaling plays a key role in neurodevelopment and neuronal maturation. Specifically, Wnt5a stimulates postsynaptic assemblies, increases glutamatergic neurotransmission and, through calcium signaling, generates nitric oxide (NO). Trying to unveil the ...

Combining Optogenetic Stimulation and Motor Training Improves Functional Recovery and Perilesional Cortical Activity

Silvestro Micera, Francesco Saverio Pavone, Maria Pasquini

Background. An ischemic stroke is followed by the remapping of motor representation and extensive changes in cortical excitability involving both hemispheres. Although stimulation of the ipsilesional motor cortex, especially when paired with motor training ...

Cell-type-specific nicotinic input disinhibits mouse barrel cortex during active sensing

Carl Petersen, Sylvain Crochet, Célia Roxane Gasselin, Benoît Hohl

Fast synaptic transmission relies upon the activation of ionotropic receptors by neurotransmitter release to evoke postsynaptic potentials. Glutamate and GABA play dominant roles in driving highly dynamic activity in synaptically connected neuronal circuit ...

Modelling and Refining Neuronal Circuits with Guidance Cues: Involvement of Semaphorins

Greta Limoni

The establishment of neuronal circuits requires neurons to develop and maintain appropriate connections with cellular partners in and out the central nervous system. These phenomena include elaboration of dendritic arborization and formation of synaptic co ...

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 ...

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 ...
