Neurite Exchange Imaging ((NEXI): A minimal model of diffusion in gray matter with inter-compartment water exchange

Ileana Ozana Jelescu, Alexandre Jean François Marie De Skowronski

Biophysical models of diffusion in white matter have been center-stage over the past two decades and are essentially based on what is now commonly referred to as the "Standard Model" (SM) of non-exchanging anisotropic compartments with Gaussian diffusion. ...

Structural architecture of the Neuronal-Glial-Vascular system

Eleftherios Zisis

Brain functionality relies on the neuronal-glial-vascular (NGV) ensemble for energy support. However, the details of the complex biological mechanisms involved in these processes and the microscopic interactions between these three components are not yet f ...

Astrocytic release of ATP through type 2 inositol 1,4,5‐trisphosphate receptor calcium signaling and social dominance behavior in mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Marie-Isabelle Guillot de Suduiraut, Fiona Hollis, Eva Ramos Fernandez

Brain mitochondrial function is critical for numerous neuronal processes. We recently identified a link between brain energy and social dominance, where higher levels of mitochondrial function resulted in increased social competitive ability. The underlyin ...

Cerebral Corpora amylacea are dense membranous labyrinths containing structurally preserved cell organelles

Henning Paul-Julius Stahlberg, Amanda Jennifer Lewis

Corpora amylacea are cell-derived structures that appear physiologically in the aged human brain. While their histological identification is straightforward, their ultrastructural composition and microenvironment at the nanoscale have remained unclear so f ...

Induction of functional dopamine neurons from human astrocytes in vitro and mouse astrocytes in a Parkinson's disease model

Gioele La Manno

Cell replacement therapies for neurodegenerative disease have focused on transplantation of the cell types affected by the pathological process. Here we describe an alternative strategy for Parkinson's disease in which dopamine neurons are generated by dir ...

Tight Coupling of Astrocyte pH Dynamics to Epileptiform Activity Revealed by Genetically Encoded pH Sensors

Henry Markram

Astrocytes can both sense and shape the evolution of neuronal network activity and are known to possess unique ion regulatory mechanisms. Here we explore the relationship between astrocytic intracellular pH dynamics and the synchronous network activity tha ...

Brain energy metabolism measured by 13C magnetic resonance spectroscopy in vivo upon infusion of [3-13C]lactate

Rolf Gruetter, João Miguel das Neves Duarte, Freya-Merret Girault

The brain uses lactate produced by glycolysis as an energy source. How lactate originated from the blood stream is used to fuel brain metabolism is not clear. The current study measures brain metabolic fluxes and estimates the amount of pyruvate that becom ...

Interactions of Peripheral Nerve Cells with Soft Micropillar Interfaces

Cédric Xavier Paulou

Regenerative peripheral nerve interfaces are particularly invasive implant devices. They rely on the growth of axons from transected nerve stumps through electrode-bearing structures in order to establish highly efficient communication channels with the ne ...

Neuronal Matrix Metalloproteinase-9 Is a Determinant of Selective Neurodegeneration

Patrick Aebischer, Christopher Towne

Selective neuronal loss is the hallmark of neurodegenerative diseases. In patients with amyotrophic lateral sclerosis (ALS), most motor neurons die but those innervating extraocular, pelvic sphincter, and slow limb muscles exhibit selective resistance. We ...

Regulation of Neurotrophic Factors and Energy Metabolism by Antidepressants in Astrocytes

Pierre Magistretti, Jean-Luc Martin, Igor Allaman

There is growing evidence that astrocytes are involved in the neuropathology of major depression. In particular, decreases in glial cell density observed in the cerebral cortex of individuals with major depressive disorder are accompanied by a reduction of ...
