Physical activity delays onset of Huntington's in mouse model 
The simple act of running in an exercise wheel delays the onset of some symptoms of Huntington’s disease in a mouse model of the fatal human disorder according to research published in the open-access journal BMC Neuroscience. These findings add insights into the pathogenesis of the disease and suggest possible preventive therapeutic targets.

Blind to Change, Even as It Stares Us in the Face
Our visual system’s inability to detect alterations to something staring us straight in the face is known as change blindness.

Harvard researchers publish MRI images of genes in action in the living brain
Biologists have just confirmed what poets have known for centuries: eyes really are windows of the soul—or at least of the brain.

Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour.

Sniffing out danger
Each human nose encounters hundreds of thousands of scents in its daily travels perched front and center on our face. Some of these smells are nearly identical, so how do we learn to tell the critical ones apart?

Epileptic Seizures Strike Much Like Earthquakes
Tools for predicting aftershocks could also work for seizures. Both systems involve “relaxation phenomena,” in which energy accumulated over a long period of time is discharged.

Scientists find a key culprit in stroke brain cell damage
Researchers have identified a key player in the killing of brain cells after a stroke or a seizure. The protein asparagine endopeptidase (AEP) unleashes enzymes that break down brain cells' DNA, scientists at Emory University School of Medicine have found.

Scientists learn what's 'up' with a class of retinal cells in mice
Harvard University researchers have discovered a new type of retinal cell that plays an exclusive and unusual role in mice: detecting upward motion. The cells reflect their function in the physical arrangement of their dendrites, branch-like structures on neuronal cells that form a communicative network with other dendrites and neurons in the brain.

Study shows compassion meditation changes the brain
Can we train ourselves to be compassionate? A new study suggests the answer is yes. Cultivating compassion and kindness through meditation affects brain regions that can make a person more empathetic to other peoples' mental states, say researchers at the University of Wisconsin-Madison.

Brain's 'sixth sense' for calories discovered
The brain can sense the calories in food, independent of the taste mechanism, researchers have found in studies with mice. The findings suggest why high-fructose corn syrup, widely used as a sweetener in foods, might contribute to obesity.

Study validates Pittsburgh Compound-B in identifying Alzheimer's disease brain toxins
A groundbreaking study confirms that Pittsburgh Compound-B (PiB) binds to the telltale beta-amyloid deposits found in the brains of patients with Alzheimer’s disease. The finding is a significant step toward enabling clinicians to provide a definitive diagnosis of Alzheimer’s disease in living patients.

Impaired sense of smell may be early indicator of Parkinson's disease
Impaired sense of smell occurs in the earliest stages of Parkinson’s disease (PD) and there is mounting evidence that it may precede motor symptoms by several years, although no large-scale studies had confirmed this.
