Cortical cell assemblies and their underlying connectivity: an in silico study

Michael Reimann, András Ecker, Daniela Egas Santander, James Bryden Isbister, Sirio Bolaños Puchet

Recent developments in experimental techniques have enabled simultaneous recordings from thousands of neurons, enabling the study of functional cell assemblies. However, determining the patterns of synaptic connectivity giving rise to these assemblies rema ...

Low-Intensity Electrostimulation Enhances Neuroregeneration and Improves Erectile Function in a Rat Model of Cavernous Nerve Injury

Nikolaos Stergiopoulos, Rodrigo Araujo Fraga Da Silva, Mikaël Nils Sturny

Background: Neurogenic erectile dysfunction (ED) following radical prostatectomy (RP) is a frequent complication often leading to erectile tissue remodeling and permanent ED. Low-intensity electrostimulation (LIES) has been shown to enhance peripheral nerv ...

A secreted factor NimrodB4 promotes the elimination of apoptotic corpses by phagocytes in Drosophila

Bruno Lemaitre, Florent François Masson, Samuel Rommelaere, Elodie Julie Virginie Ramond, Bianca Marie Petrignani

Programmed cell death plays a fundamental role in development and tissue homeostasis. Professional and non-professional phagocytes achieve the proper recognition, uptake, and degradation of apoptotic cells, a process called efferocytosis. Failure in effero ...

Diversity of Reactive Astrogliosis in CNS Pathology: Heterogeneity or Plasticity?

Jordan Squair

Astrocytes are essential for the development and homeostatic maintenance of the central nervous system (CNS). They are also critical players in the CNS injury response during which they undergo a process referred to as "reactive astrogliosis." Diversity in ...

A cell fitness selection model for neuronal survival during development

Gioele La Manno

Developmental cell death plays an important role in the construction of functional neural circuits. In vertebrates, the canonical view proposes a selection of the surviving neurons through stochastic competition for target-derived neurotrophic signals, imp ...

A Computational Model of Loss of Dopaminergic Cells in Parkinson's Disease Due to Glutamate-Induced Excitotoxicity

Srikanth Ramaswamy, Vignayanandam Ravindernath Muddapu

Parkinson's disease (PD) is a neurodegenerative disease associated with progressive and inexorable loss of dopaminergic cells in Substantia Nigra pars compacta (SNc). Although many mechanisms have been suggested, a decisive root cause of this cell loss is ...

Endogenous SHG and 2PEF coherence imaging of substructures in neurons in 3D

Sylvie Roke, Carlos Alberto Macias Romero, Marie Eve Pascale Didier, Claire Jacqueline Léa Teulon

Neuronal morphology, long-distance transport and signalling critically depend on the organization of microtubules in the cytoskeleton. Second harmonic generation (SHG) imaging has been recognized as a potentially powerful tool for in situ label-free neuroi ...

RNA sequencing dataset describing transcriptional changes in cervical dorsal root ganglia after bilateral pyramidotomy and forelimb intramuscular gene therapy with an adeno-associated viral vector encoding human neurotrophin-3

Claudia Kathe

Unilateral or bilateral corticospinal tract injury in the medullary pyramids in adult rats causes anatomical and physiological changes in proprioceptive neurons projecting to the cervical spinal cord accompanied by hyperreflexia and abnormal behavioural mo ...

Required growth facilitators propel axon regeneration across complete spinal cord injury

Grégoire Courtine, Mark Andrew Anderson, Nicholas David James, Cheng Wang, Sabry Leonardo Barlatey, Michael V. Sofroniew

Transected axons fail to regrow across anatomically complete spinal cord injuries (SCI) in adults. Diverse molecules can partially facilitate or attenuate axon growth during development or after injury1,2,3, but efficient reversal of this regrowth failure ...

Optogenetic Peripheral Nerve Immunogenicity

Optogenetic technologies have been the subject of great excitement within the scientific community for their ability to demystify complex neurophysiological pathways in the central (CNS) and peripheral nervous systems (PNS). The excitement surrounding opto ...

Preferential Enhancement of Sensory and Motor Axon Regeneration by Combining Extracellular Matrix Components with Neurotrophic Factors

Silvestro Micera

After peripheral nerve injury, motor and sensory axons are able to regenerate but inaccuracy of target reinnervation leads to poor functional recovery. Extracellular matrix (ECM) components and neurotrophic factors (NTFs) exert their effect on different ne ...

Morphological Diversity Strongly Constrains Synaptic Connectivity and Plasticity

Henry Markram, Eilif Benjamin Muller, Srikanth Ramaswamy, Michael Reimann

Synaptic connectivity between neurons is naturally constrained by the anatomical overlap of neuronal arbors, the space on the axon available for synapses, and by physiological mechanisms that form synapses at a subset of potential synapse locations. What i ...

Influencing axon regeneration after spinal cord injury

Mark Andrew Anderson

Spinal cord injury (SCI) results in a severing of axonal connections that leads to permanent sensorimotor deficits. In cases of incomplete injury, rehabilitation paradigms have been reported to be successful in improving behavioral outcome in humans with S ...

Focal release of neurotrophic factors by biodegradable microspheres enhance motor and sensory axonal regeneration in vitro and in vivo

Silvestro Micera

Neurotrophic factors (NTFs) promote nerve regeneration and neuronal survival after peripheral nerve injury. However, drawbacks related with administration and bioactivity during long periods limit their therapeutic application. In this study, PLGA microsph ...

Cortical neurons gradually attain a post-mitotic state

Johannes Gräff

Once generated, neurons are thought to permanently exit the cell cycle and become irreversibly differentiated. However, neither the precise point at which this post-mitotic state is attained nor the extent of its irreversibility is clearly defined. Here we ...

When Neurons Fail - Technical Report

Rachid Guerraoui, El Mahdi El Mhamdi

Neural networks have been traditionally considered robust in the sense that their precision degrades gracefully with the failure of neurons and can be compensated by additional learning phases. Nevertheless, critical applications for which neural networks ...

Long Term Hippocampal and Cortical Changes Induced by Maternal Deprivation and Neonatal Leptin Treatment in Male and Female Rats

Maternal deprivation (MD) during neonatal life has diverse long-term behavioral effects and alters the development of the hippocampus and frontal cortex, with several of these effects being sexually dimorphic. MD animals show a marked reduction in their ci ...

Astrocytes: New Targets for the Treatment of Neurodegenerative Diseases

Pierre Magistretti, Sylvain Eric Lengacher, Charles Léonard Finsterwald

The causes of neurodegenerative disorders are multiple, and for most of them a mechanistic understanding is still lacking. However, neurodegenerative diseases such as Alzheimer disease (AD), amyotrophic lateral sclerosis (ALS) and Parkinson disease (PD) al ...

Disrupting astrocyte-neuron lactate transfer persistently reduces conditioned responses to cocaine
