Weekly Neuroscience Update

Researchers propose forgetting memories or things we have learned may be a functional feature in the brain and actually an additional form of learning.

Scientists have developed a device for recording brain activity that is more compact and affordable than the solutions currently on the market. With its high signal quality and customizable configuration, the device could help people with restricted mobility regain control of their limbs or provide advance warnings of an impending seizure to patients with epilepsy. The article presenting the device and testing results came out in Experimental Brain Research.

A new, large-scale study led by scientists at the Yale School of Public Health has established a robust link between long-term ozone exposure and an increased risk of cognitive impairment in older adults.

A new study found that frailty was a strong risk factor for dementia, even among people who are at a high genetic risk for dementia, and that it might be modified through a healthy lifestyle.

A systematic review published in the scientific journal Addiction has found that cannabis use leads to acute cognitive impairments that may continue beyond the period of intoxication.

Neuroscientists have identified a specific signal that young children and even babies use to determine whether two people have a strong relationship and a mutual obligation to help each other.

Finally this week a new study reveals how the body produces different health-promoting signaling molecules in an organ-specific manner following exercise at different points during the day.
