Running Throughout Middle Age Keeps ‘Old’ Adult-born Neurons ‘Wired’

A new study provides novel insight into the benefits of exercise, which should motivate adults to keep moving throughout their lifetime, especially during middle age. Long-term exercise profoundly benefits the aging brain and may prevent aging-related memory function decline by increasing the survival and modifying the network of the adult-born neurons born during early adulthood, and thereby facilitating their participation in cognitive processes.

Potential Treatment Target for Rare Form of Infant Epilepsy Identified

New research from Tufts University School of Medicine and the Graduate School of Biomedical Sciences suggests that the timing of the death of certain inhibitory neurons in the brain shortly after birth may be at least partly to blame for infantile spasms syndrome (ISS), a rare but devastating form of epilepsy that develops most frequently between four and eight months of age but can emerge within weeks of birth until ages 4 or 5.

FAU, Israel Scientists ‘Team Up’ to Tackle Alzheimer’s-related Mood Disorders

Researchers from Florida Atlantic University, in collaboration with Tel Aviv University, have received a two-year, $379,177 grant from the National Institute on Aging, National Institutes for Health, on a collaborative project to study mood-disorders changes in Alzheimer’s disease.

Molecular ‘Connector’ Helps Cocaine Latch on to Brain Cells, Even When Drug Is in Low Doses

Scientists have long known that cocaine works by latching on to molecular connectors on the surface of brain cells, allowing dopamine, a chemical that promotes feelings of pleasure and reward, to accumulate in the space between brain cells. Now, Johns Hopkins Medicine scientists say they have found a molecular connector, known as the BASP1 receptor, that binds cocaine, even when the drug is present in very low doses.

Distinct Parkinson’s Disease Symptoms Tied to Different Brain Pathways

Neurobiologists have found that identifiable brain pathways are linked with specific debilitating symptoms of Parkinson’s disease. The findings could help form the basis for improving therapeutic strategies for precise symptoms of Parkinson’s at various levels of disease progression.
