The happiness we feel after a particular event or activity diminishes each time we experience that event, a phenomenon known as hedonic adaptation. But giving to others may be the exception to this rule, according to new research.

Parkinson’s disease protein buys time for cell repair

Loss of the protein Parkin causes certain forms of Parkinson’s disease, a neurodegenerative condition involving death of neurons. Scientists have now shown that Parkin stifles cell death by blocking BAK, a protein which is a central player in cell deat…

New memory study first to use intracranial recordings

New research is first memory study to use intracranial recordings to better understand how maturation of the prefrontal cortex drives memory development.

12 foods to boost brain function

The diet can have a significant impact on the brain’s function. A brain-healthy diet, rich in antioxidants and omega-3 fatty acids, can boost memory and learning while staving off neurodegenerative disorders, such as Alzheimer’s disease. Here, we look …

Drugs of abuse: Identifying the addiction circuit

What happens in the brain of a compulsive drug user? Neurobiologists have discovered that the brain circuit connecting the decision-making region to the reward system is stronger in compulsive animals. The researchers also found that by decreasing the …

How the brain reacts to loss of vision

If mice lose their vision immediately after birth due to a genetic defect, this has a considerable impact, both on the organization of the cerebral cortex and on memory. Researchers demonstrated that, in the months after blindness emerged, the density …

Computer hardware designed for 3D games could hold the key to replicating human brain

Researchers have created the fastest and most energy efficient simulation of part of a rat brain using off-the-shelf computer hardware.

Lasting impact of concussions on young adults

Researchers have found that young adults who experienced repetitive mild traumatic brain injury (mTBI), or concussions, can experience persistent cognitive changes as well as altered brain activity.

MRI technique shows unique signatures of concussion in rugby players

The research team studied the brains of young female athletes and used a technique that combined multiple brain imaging measures to be able to look at structural and functional information at the same time. The result was a much more sensitive and comp…

Nutrients in blood linked to better brain connectivity, cognition in older adults

A new study links higher levels of several key nutrients in the blood with more efficient brain connectivity and performance on cognitive tests in older adults.
