Structural architecture of the Neuronal-Glial-Vascular system

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 ...

Neuronal Correlates of Tactile Working Memory in Prefrontal and Vibrissal Somatosensory Cortex

Vahid Esmaeili

Tactile working memory engages a broad network of cortical regions in primates. To assess whether the conclusions drawn from primates apply to rodents, we examined the vibrissal primary somatosensory cortex (vS1) and the prelimbic cortex (PL) in a delayed ...

Learning Recruits Neurons Representing Previously Established Associations in the Corvid Endbrain

Galyna Pidpruzhnykova

Crows quickly learn arbitrary associations. As a neuronal correlate of this behavior, single neurons in the corvid endbrain area nidopallium caudolaterale (NCL) change their response properties during association learning. In crows performing a delayed ass ...

Imaging the Dynamics of Neocortical Population Activity in Behaving and Freely Moving Mammals

Carl Petersen

The development of functional imaging techniques applicable to neuroscience and covering a wide range of spatial and temporal scales has greatly facilitated the exploration of the relationships between cognition, behaviour and electrical brain activity. Fo ...

Astrocyte–neuron co-culture on microchips based on the model of SOD mutation to mimic ALS

Philippe Renaud, Pierre Magistretti, Patrick Aebischer, Sylvain Eric Lengacher, Anja Kunze, Elisabeth Anne Dirren

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease. ALS is believed to be a non-cell autonomous condition, as other cell types, including astrocytes, have been implicated in disease pathogenesis. Hence, to facilitate the developmen ...

Cerebral glutamine metabolism under hyperammonemia determined in vivo by localized H-1 and N-15 NMR spectroscopy

Rolf Gruetter, Cristina Ramona Cudalbu Moldovan, João Miguel das Neves Duarte, Bernard Lanz, Yves Pilloud

Brain glutamine synthetase (GS) is an integral part of the glutamate-glutamine cycle and occurs in the glial compartment. In vivo Magnetic Resonance Spectroscopy (MRS) allows noninvasive measurements of the concentrations and synthesis rates of metabolites ...

Diminished hippocalcin expression in Huntington's disease brain does not account for increased striatal neuron vulnerability as assessed in primary neurons

Nicole Déglon

Hippocalcin is a neuronal calcium sensor protein previously implicated in regulating neuronal viability and plasticity. Hippocalcin is the most highly expressed neuronal calcium sensor in the medium spiny striatal output neurons that degenerate selectively ...

Investigation of novel calcium-related events as suspected contributors to neurodegeneration

Calcium regulates neuronal signaling and viability through a vast range of cellular and molecular mechanisms. However, many details of these mechanisms still remain to be elucidated. It is believed that calcium-related pathways may comprise promising thera ...

Rapid Functional Maturation of Nascent Dendritic Spines

Graham Knott

Spine growth and retraction with synapse formation and elimination plays an important role in shaping brain circuits during development and in the adult brain, yet the temporal relationship between spine morphogenesis and the formation of functional synaps ...

Progressive and selective striatal degeneration in primary neuronal cultures using lentiviral vector coding for a mutant huntingtin fragment

Patrick Aebischer, Nicole Déglon, Diana Zala, Valérie Gafner

A lentiviral vector expressing a mutant huntingtin protein (htt171-82Q) was used to generate a chronic model of Huntington's disease (HD) in rat primary striatal cultures. In this model, the majority of neurons expressed the transgene so that Western blot ...
