Researchers identify key gene linked to heroin addiction

Opioid use disorder is associated with more than 350,000 deaths annually worldwide. Guided by the need for an increased understanding of critical neurobiological features of addiction, researchers have now found a unique molecular signature and genes in the orbitofrontal cortex associated with heroin-seeking behavior.

Research reveals how dendrites connect memories in the brain

If you've ever noticed how memories from the same day seem connected while events from weeks apart feel separate, a new study reveals the reason: Our brains physically link memories that occur close in time not in the cell bodies of neurons, but rather in their spiny extensions called dendrites.

Targeting brain’s waste removal system may help combat cognitive decline

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease, among others.
