The neurogenic subventricular zone (SVZ) of the lateral ventricle is a potential source for neuronal replacement in the postnatal or adult neocortex after injury. Here we present a novel model system to directly explore the cellular mechanisms of this proc ...
BACKGROUND: In the field of neuroscience microarray gene expression profiles on anatomically defined brain structures are being used increasingly to study both normal brain functions as well as pathological states. Fluorescent tracing techniques in brain t ...
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 ...
The coupling between synaptic activity and glucose utilization (neurometabolic coupling) is a central physiological principle of brain function that has provided the basis for 2-deoxyglucose-based functional imaging with positron emission tomography (PET). ...
Large network monitoring of electrogenic cells by means of micro electrode arrays (MEA) has become a valuable methodology in electrophysiology. In order to understand the mechanisms of learning (plasticity) and memory in fundamental neuroscience it is impe ...
The patch-clamp technique has allowed detailed studies on the electrical properties of neurons. Dye loading through patch pipettes has allowed characterizing the morphological properties of the neurons. In addition, the patch-clamp technique also allows ha ...
We report a comprehensive in vitro study of the photo-oxidative stress on different biomolecular and cellular targets generated in the presence of fullerol C-60(OH)(n), a novel, fullerene-based and water-soluble sensitizer of singlet oxygen ((1)Delta(g)). ...
In the adult mammalian brain, neural stem cells persist in the subventricular zone and the hippocampus, producing new functional neurons throughout life. Whether and how adult neurogenesis maintains brain function remains highly debated. This question is o ...
This article throws new light on the possible role of synapses in information transmission through theoretical analysis and computer simulations. We show that the internal dynamic state of a synapse may serve as a transient memory buffer that stores inform ...
Parkinson's disease (PD) is a neurologic disorder resulting from the loss of dopaminergic neurons in the brain. Two lines of evidence suggest that the protein alpha-synuclein plays a role in the pathogenesis of PD: Fibrillar alpha-synuclein is a major comp ...
