A new study of reaching and grasping with hand or food reveals novel brain insights. 

Researchers have discovered a new mechanism by which clumps of tau protein are created in the brain, killing brain cells and causing Alzheimer’s disease.

New research reveals a single brain region links depression and anxiety, heart disease and treatment sensitivity. 

A Danish study shows that people doing hard physical work have a 55-percent higher risk of developing dementia than those doing sedentary work.

A new theory suggests electromagnetic energy in the brain enables neurons and brain regions to create consciousness and our ability to critically think.

Brain cell dysfunction in low oxygen is, caused by the very same responder system that is intended to be protective, according to a new published study.

A new study reveals a correlation between multimedia multitasking, memory loss, and difficulties in maintaining attention.

A recent study reveals how gene control mechanisms define the identity of developing neurons in the brainstem. The researchers also showed that a failure in differentiation of the brainstem neurons leads to behavioural abnormalities, including hyperactivity and attention deficit.

The decline of striosomal activity in the brain may explain why people lose the motivation to learn as they age.

Finally this week, researchers have shown how a genetic mutation throws off the timing of the biological clock, causing a common sleep syndrome called delayed sleep phase disorder.
