Hearing loss affects more than 60 percent of adults aged 70 and older in the United States and is known to be related to an increased risk of dementia. The reason for this association is not fully understood.

What is the mechanism that allows our brains to incorporate new information about the world, and form memories? New work by a team of neuroscientists led by Dr Tomás Ryan from Trinity College Dublin shows that learning occurs through the continuous

Contrary to the commonly-held view, the brain does not have the ability to rewire itself to compensate for the loss of sight, an amputation or stroke, for example, say scientists from the University of Cambridge and Johns Hopkins University.

Using a specialized device that translates images into sound, Georgetown University Medical Center neuroscientists and colleagues showed that people who are blind recognized basic faces using the part of the brain known as the fusiform face area, a region

In Alzheimer's disease and related dementias, cognitive decline is driven by the overaccumulation of a normal brain protein known as tau. Wherever tau builds up, nearby brain tissue starts to degenerate and die.

An intense international effort to improve the resolution of magnetic resonance imaging (MRI) for studying the human brain has culminated in an ultra-high resolution 7 Tesla scanner that records up to 10 times more detail than current 7T scanners and over

Researchers have discovered that a part of the brain associated with working memory and multisensory integration may also play an important role in how the brain processes social cues. Previous research has shown that neurons in the ventrolateral prefront

If you've had a near miss accident in your car or suffered the intimidation of a menacing person, you've probably felt it -- a psychological reaction to a threat called a fight or flight response. Your heart rate climbs, anxiety washes over you, you mig

Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study from Yale and Columbia Universit

Each year in the United States there are more than 3 million cases of peripheral neuropathy, wherein nerves outside of the brain and spinal cord are damaged and cause pain and loss of feeling in the affected areas. Peripheral neuropathy can occur from dia

Damage to the body's peripheral nerves can cause pain and movement disorders. Researchers at the Leipzig University have recently investigated how damaged nerves can regenerate better. They found that fat tissue strongly supports the Schwann cells needed

Optimal windows exist for action and perception during the 0.8 seconds of a heartbeat, according to research published November 28 in the open access journal PLOS Biology. The sequence of contraction and relaxation is linked to changes in the mot
