The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Insulin may slow or prevent damage caused by toxic proteins in Alzheimer's disease

A Northwestern University-led research team reports that insulin, by shielding memory-forming synapses from harm, may slow or prevent the damage and memory loss caused by toxic proteins in Alzheimer's disease.

Genetic change prevents cell death in mouse model of Parkinson's disease

By shifting a normal protective mechanism into overdrive, a University of Wisconsin-Madison scientist has completely shielded mice from a toxic chemical that would otherwise cause Parkinson's disease.

The end of sex as we once knew it

Women are not from Venus any more than men are from Mars. But even though both sexes are perfectly terrestrial beings, they are not lacking in other differences. And not only in their reproductive organs and behavior, either, but in such unsexy characteristics as the propensity for drug abuse, fine motor control, reaction to stress, moods and many brain structures.

BioGenes as new designated partner in EU funded dementia project

BioGenes GmbH, a specialist in sophisticated antibody development, has been chosen as a new partner of cNEUPRO. cNEUPRO is a EU funded research project to analyse neurodegenerative diseases and discover novel biomarkers, and so improve early and differential diagnosis of Alzheimer's dementia.

New insights into growth factor's role in brain development

New research sheds light on a neural growth factor called proBDNF, finding that it is present and potentially active during the perinatal period when the brain's circuitry and memory-encoding regions are being refined.

Brain cells called astrocytes, not neurons, lull the brain to sleep

Brain cells called astrocytes help to cause the urge to sleep that comes with prolonged wakefulness, according to a study in mice, funded by the National Institutes of Health.

Stress may speed growth of melanoma tumors

For patients with a particularly aggressive form of skin cancer - malignant melanoma - stress, including that which comes from simply hearing that diagnosis, might amplify the progression of their disease.

Recent reports regarding mercury and high fructose

ChemRisk, a leading scientific consulting firm, was asked by the Corn Refiners Association (CRA) to examine the recent publication by Institute for Agriculture and Trade Policy (IATP), "Not So Sweet: Missing Mercury and High Fructose Corn Syrup," and the Environmental Health journal publication "Mercury from chlor-alkali plants: measured concentrations in food product sugar," by Dufault et al, 2009, and to offer our comments and analysis.

Physical therapists test mechanical arm to help patients recover from stroke, traumatic brain injury

Physical therapists at UT Southwestern Medical Center are evaluating a new mechanical arm that allows people recovering from neurological injuries such as strokes and traumatic brain injury to enter a virtual world where they can repeatedly practice movements needed to regain arm strength and movement.
