Obesity research boosted by watching hunger in the brain
Scientists can now measure how full or hungry a mouse feels, thanks to a new technique which uses imaging to reveal how neurons behave in the part of the brain which regulates appetite.   view more (2007-11-08)

Parkinson's mutation stunts neurons
Mutations in a key brain protein known to underlie a form of Parkinson's disease (PD) wreaks its damage by stunting the normal growth and branching of neurons, researchers have found.   view more (2006-11-27)

Cocaine-induced synaptic plasticity linked to persistent addictive behaviors
The persistent nature of addiction is its most devastating feature. Understanding the mechanism underlying this phenomenon is the key for designing efficient therapy. Two separate studies published by Cell Press is the August 14 issue of the journal Neuron identify specific cocaine-induced changes... view more (2008-08-14)

MIT: Stem-cell therapies for brain more complicated than thought
An MIT research team's latest finding suggests that stem cell therapies for the brain could be much more complicated than previously thought.   view more (2007-11-28)

Therapeutic cloning treats Parkinson's disease in mice
Research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) has shown that therapeutic cloning, also known as somatic-cell nuclear transfer (SCNT), can be used to treat Parkinson's disease in mice. The study's results are published in the March 23 online edition of the journal... view more (2008-03-24)

Mapping the neural landscape of hunger
The compelling urge to satisfy one's hunger enlists structures throughout the brain, as might be expected in a process so necessary for survival.   view more (2006-08-17)

Study of the drug, Isradipine, to determine if it slows or prevents Parkinson's disease
Gloria E. Meredith, Ph.D., collaborated with D. James Surmeier, Ph.D. and other scientists at Northwestern University to study the drug, Isradipine, and its possible effects on Parkinson's disease.   view more (2007-06-14)

Mechanism of nicotine's learning effects explored
While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory—a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity... view more (2007-04-05)

New research promising for improving brain cell survival after brain injury
Scientists at Melbourne's Howard Florey Institute have found a protein in the brain that can save neurons from dying after experiencing traumatic brain injury from incidents such as stroke, car accidents and falls.   view more (2006-07-11)

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments
UC Irvine School of Medicine researchers have discovered how new neurons born from endogenous neural stem cells are sent to regions of the brain where they can replace old and dying cells, a finding that suggests how stem cell therapies can be specifically targeted to brain regions affected by... view more (2005-06-24)

"Booster rocket" malfunction implicated in Huntington's disease
CNRS and Inserm research scientists at the Institut Curie have shed new light on the function of huntingtin, the protein whose mutation underlies Huntington's disease. This neurodegenerative disease, like Alzheimer's or Parkinson's, is characterized by the abnormal death of certain neurons. The... view more (2004-07-07)

Astrocytes and synaptic plasticity
By mopping up excess neurotrophic factor from neuronal synapses, astrocytes may finely tune synaptic transmission to affect processes such as learning and memory, say Bergami et al.   view more (2008-10-13)

Smell experience during critical period alters brain
Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement.   view more (2007-12-06)

Autistic brain has fewer neurons for processing emotion
For the first time, research has shown that the autistic brain has fewer neurons in an area related to emotion and social behavior, according to a new study published in the July 19 issue of The Journal of Neuroscience.   view more (2006-07-20)

Killer carbs -- Monash scientist finds the key to overeating as we age
A Monash University scientist has discovered key appetite control cells in the human brain degenerate over time, causing increased hunger and potentially weight-gain as we grow older.   view more (2008-08-21)

Brain's impaired ability to sense glucose might play role in type 2 diabetes
New findings from studies in mice suggest that defects in the brain's ability to respond to glucose play a role in the development of non-insulin dependent (type 2) diabetes, and that a high-fat diet may contribute to impairing brain cells' ability to regulate glucose throughout the body.   view more (2007-08-30)

Researchers get neurons and silicon talking
European researchers have created an interface between mammalian neurons and silicon chips.   view more (2006-03-28)

Telling axons where to go - and grow
In a recent study, Dr. Ingolf Bach and colleagues from the University of Massachusetts Medical School, Worcester and the University of Hamburg (Germany) describe a novel role for the ubiquitin/proteosome protein degradation pathway in the regulation of local actin dynamics in neurons.   view more (2005-10-03)

Mice use specialized neurons to detect carbon dioxide in the air
For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby.   view more (2007-08-17)

Penn researchers engineer first system of human nerve-cell tissue
Researchers at the University of Pennsylvania School of Medicine have demonstrated that living human nerve cells can be engineered into a network that could one day be used for transplants to repair damaged to the nervous system. They report their findings in the February issue of the Journal of... view more (2008-02-27)

Molecular structure reveals how botulinum toxin attaches to nerve cells
Botulism is a life-threatening disease caused by exposure to botulinum neurotoxins, which are among the most potent toxins known. These neurotoxins are produced by Clostridium botulinum, a bacterium found in soil and food.   view more (2006-12-14)

Huntington's disease study shows animal models on target
An international team of researchers has published a benchmark study showing that gene expression in several animal models of Huntington's Disease (HD) closely resembles that of human HD patients.   view more (2007-08-01)

Tracking the memory trace
Memory formation follows a dynamic pattern, allowing for retrieval from different areas of the brain, depending on when an organism needs to remember, said a researcher at Baylor College of Medicine.   view more (2005-12-05)

Neurotransmitter orexin associated with pleasure and reward pathways in the brain
Researchers at the University of Pennsylvania School of Medicine have discovered that the recently identified neurotransmitter orexin (also known as hypocretin) influences reward processing by activating neurons in the lateral hypothalamus region of the brain.   view more (2005-08-26)
