Recapitulating De Novo Alpha-Synuclein Fibrillization in a Novel Neuronal Model of Parkinson's Disease

Mohamed Bilal Fares

Athough it has been established for over 100 years that Lewy bodies (LBs) represent the major pathological hallmark of Parkinson's disease (PD), we still do not know why these fibrillar intra-neuronal inclusions of the α-Synuclein (α-Syn) protein form, and ...

A Cellular Perspective on Brain Energy Metabolism and Functional Imaging

Pierre Magistretti, Igor Allaman

The energy demands of the brain are high: they account for at least 20% of the body's energy consumption. Evolutionary studies indicate that the emergence of higher cognitive functions in humans is associated with an increased glucose utilization and expre ...

Sparse, reliable, and long-term stable representation of periodic whisker deflections in the mouse barrel cortex

Johannes Maria Mayrhofer

The rodent whisker system is a preferred model for studying plasticity in the somatosensory cortex (barrel cortex). Contrarily, only a small amount of research has been conducted to characterize the stability of neuronal population activity in the barrel c ...

Statistical structure of neural spiking under non-Poissonian or other non-white stimulation

Tilo Schwalger

Nerve cells in the brain generate sequences of action potentials with a complex statistics. Theoretical attempts to understand this statistics were largely limited to the case of a temporally uncorrelated input (Poissonian shot noise) from the neurons in t ...

Cell-type specific function of GABAergic neurons in layers 2 and 3 of mouse barrel cortex

Carl Petersen

GABAergic neurons are a minor fraction of the neocortical neuronal population, but they are highly diverse in their features. The GABAergic neurons can be divided into three largely non-overlapping groups, defined through the expression of ionotropic serot ...

The H50Q Mutation Enhances alpha-Synuclein Aggregation, Secretion, and Toxicity

Hilal Lashuel, Giovanni Dietler, Bruno Claude Daniel Fauvet, Francesco Simone Ruggeri, Anne-Laure Mahul Mellier, Abid Oueslati, Martial Mbefo Kamdem, Ossama Mohamed Salah El-Dien El-Sayed Ibrahim Khalaf, Filip Vercruysse

Over the last two decades, the identification of missense mutations in the alpha-synuclein (alpha-Syn) gene SNCA in families with inherited Parkinson disease (PD) has reinforced the central role of alpha-Syn in PD pathogenesis. Recently, a new missense mut ...

Cortical Interneuron Loss and Symptom Heterogeneity in Huntington Disease

Objective: The cellular basis of variable symptoms in Huntington disease (HD) is unclear. One important possibility is that degeneration of the interneurons in the cerebral cortex, which play a critical role in modulating cortical output to the basal gangl ...

Single-cell RT-PCR, a technique to decipher the electrical, anatomical, and genetic determinants of neuronal diversity

Henry Markram

The patch-clamp technique has allowed for detailed studies on the electrical properties of neurons. Dye loading through patch pipettes enabled characterizing the morphological properties of the neurons. In addition, the patch-clamp technique also allows fo ...

Hyperconnectivity and Slow Synapses during Early Development of Medial Prefrontal Cortex in a Mouse Model for Mental Retardation and Autism

Michele Giugliano

Neuronal theories of neurodevelopmental disorders (NDDs) of autism and mental retardation propose that abnormal connectivity underlies deficits in attentional processing. We tested this theory by studying unitary synaptic connections between layer 5 pyrami ...
