Virtual Fly Brain: An ontology-linked schema of the Drosophila Brain
Drosophila neuro-anatomical data is scattered across a large, diverse literature dating back over 75 years and a growing number of community databases. Lack of a standardized nomenclature for neuro…

Magnetoencephalography May Allow the Electromagnetic 'Biopsy' of Central Nervous System Neoplastic Tissue
Developing a non-invasive method for definitively diagnosing intracranial neoplasms would reduce the risks involved with diagnosis and improve the treatment of such tumors. We used magnetoencephalo…

Modularity maps reveal community structure in the resting human brain
The brain is a complex network of interconnecting neurons that combines regional specificity with distributed processing. Recent advances in the field of network theory have facilitated ground-brea…

Cerebral and Spinal Modulation of Pain by Emotions
Emotions have powerful effects on pain perception. However, the brain mechanisms underlying these effects remain largely unknown. In this study, we combined functional cerebral imaging with psychop…

Neuronal plasticity: cell-based strategy for target identification and validation
While growing neurites are relatively plastic during development, their plasticity levels drop rapidly as neurons mature and become integrated into neuronal networks. As a consequence, the central …

Endogenous human brain dynamics recover slowly following cognitive effort
In functional magnetic resonance imaging, the brain’s response to experimental cognitive tasks is usually assumed to be independent of endogenous oscillations. To test this assumption, we measured …

MR Neurography and Diffusion Tensor Imaging: Origin, History and Impact
Objective: Methods were invented that made it possible to image peripheral nerves in the body and to image neural tracts in the brain. Over a 15 year period, these techniques – MR Neurography and…

Human microglial cells synthesize albumin in brain
Albumin has been implicated in Alzheimer’s disease since it can bind to and transport amyloid beta, the causative agent; albumin is also a potent inhibitor of amyloid beta polymerization. In a pilo…
