Epilepsy and brain pathology linked together by the protein ADK
The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes.   view more (2008-01-03)

Complexity constrains evolution of human brain genes
Despite the explosive growth in size and complexity of the human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has actually slowed since the split, millions of years ago, between human and chimpanzee.   view more (2006-12-26)

Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during... view more (2006-03-06)

Tumor-killing virus selectively targets diseased brain cells
New findings show that a specialized virus with the ability to reproduce its tumor-killing genes can selectively target tumors in the brains of mice and eliminate them.   view more (2008-02-20)

Proteins in urine predict brain damage in laboratory animals
The study dealt with the development and prevention of strokes in particular rats which had spontaneously developed extremely high blood pressure. Such a high blood pressure level leads within a few weeks to damage to the kidneys, heart and brain such that the rats die. The researchers found that... view more (1999-06-21)

Researchers studying how singing bats communicate
Bats are the most vocal mammals other than humans, and understanding how they communicate during their nocturnal outings could lead to better treatments for human speech disorders, say researchers at Texas A&M University.   view more (2007-10-19)

UCLA/Toronto researchers unlock key to memory storage in brain
Scientists know little about how the brain assigns cells to participate in encoding and storing memories. Now a UCLA/University of Toronto team has discovered that a protein called CREB controls the odds of a neuron playing a role in memory formation.   view more (2007-04-20)

Color contrast is 'seen' by the brain early doors
Colour contrast is detected much earlier in the brain than previously thought, a new study shows.   view more (2007-09-10)

1 sleepless night increases dopamine in the human brain
Just one night without sleep can increase the amount of the chemical dopamine in the human brain, according to new imaging research in the August 20 issue of The Journal of Neuroscience.   view more (2008-08-20)

Unraveling where chimp and human brains diverge
Six million years ago, chimpanzees and humans diverged from a common ancestor and evolved into unique species.   view more (2006-11-14)

Darwin's greatest challenge tackled: the mystery of eye evolution
When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. Scientists at the European Molecular Biology Laboratory (EMBL) have... view more (2004-10-26)

Breast cancer subtypes linked to survival from secondary brain tumors
Screening breast cancers for three receptors could help doctors predict the likely survival of patients with brain metastases.   view more (2008-02-28)

Post brain injury: New nerve cells originate from neural stem cells
Most cells in the human brain are not nerve cells, but supporting cells (glial cells). They serve as a framework for nerve cells and play an important role in the wound reaction that occurs with injuries to the brain.   view more (2008-03-12)

Hallucinations in schizophrenia linked to brain area that processes voices
For the first time, researchers using magnetic resonance imaging (MRI) have found both structural and functional abnormalities in specific brain regions of schizophrenic patients who experience chronic auditory hallucinations, according to a study published in the August issue of Radiology.   view more (2007-07-31)

Fly with brain tumor may shed light on cancer causing genes
A study showing how the expression of genes changes when the brain tissue of fruit flies becomes cancerous is published this week in BMC Genomics. As the function of many of these genes is conserved across evolution, the researchers expect their results will help us to understand why human brain... view more (2004-04-14)

FSU anthropologist confirms 'Hobbit' indeed a separate species
After the skeletal remains of an 18,000-year-old, Hobbit-sized human were discovered on the Indonesian island of Flores in 2003, some scientists thought that the specimen must have been a pygmy or a microcephalic — a human with an abnormally small skull.   view more (2007-01-30)

Computer obeys thoughts via Brain-Computer Interface
A research group led by Academy Professor Mikko Sams is developing a brain-computer interface, a device that transforms electrical or magnetic brain signals into commands a computer can understand. Equipment of this kind is necessary. For instance, it enables physically disabled persons to use a... view more (2005-03-02)

Commonly used drug may prevent fetal alcohol syndrome
Fetal alcohol syndrome (FAS) is often called the number one preventable birth defect.   view more (2006-02-21)

Hearing where it's at: how humans and gerbils learn to locate sound
Humans behave like small mammals when tracing the source of a low-pitched sound, according to a study funded by the Medical Research Council at University College London. UCL researchers have devised a new model for how the human brain tracks sound, which could eventually help engineers develop... view more (2004-08-02)

Human cerebellum and cortex age in very different ways
Researchers have found that the two primary areas of the human brain appear to age in radically different ways: The cortex used in higher-level thought undergoes more extensive changes with age than the cerebellum, which regulates basic processes such as heartbeat, breathing and balance.   view more (2005-08-02)

Cell phone use not linked to cancer risk
Long or short-term cell phone use is not associated with increased cancer risk, according to a study in the December 6 issue of the Journal of the National Cancer Institute.   view more (2006-12-06)

Scientists a step closer to understanding how anaesthetics work in the brain
An important clue to how anaesthetics work on the human body has been provided by the discovery of a molecular feature common to both the human brain and the great pond snail nervous system, scientists say today.   view more (2007-07-20)

Why the brain has 'gray matter'
By borrowing mathematical tools from theoretical physics, scientists have recently developed a theory that explains why the brain tissue of humans and other vertebrates is segregated into the familiar "gray matter" and "white matter."   view more (2006-01-12)

New research targets treatment for dementia and brain injuries
Queensland Brain Institute (QBI) researchers have identified a process that could lead to development of repair mechanisms for people suffering from dementia and acquired brain injury.   view more (2005-11-29)

Studying Alzheimer's Disease, Parkinson's Disease and Aging
Studying Alzheimer's Disease, Parkinson's Disease and Aging Human Brain Proteome Project: Defining of Standards and Tasks Proteins serve as Biomarkers of Neurodegenerative Diseases One of the main challenges of this century is the understanding of our brain: Why are we getting senile? Which... view more (2003-09-11)
