Distinct Brain Mechanisms for Emotion Generation and Regulation Identified

Researchers have identified multiple brain regions that are unique to regulating emotions. The study is among the first of its kind to separate activity relating to emotion generation from emotion regulation in the human brain.

Designing a Vaccine To Block “Zombie Drug” Xylazine

Scripps Research chemical biologists have developed a vaccine to block the effects of xylazine’s toxicity. The vaccine works by training the immune system to attack the drug, which is described in a new paper published in Chemical Communications.

Why Are Some Memories Retained, While Others Are Lost?

A new study proposes a mechanism that determines which memories are tagged as important enough to linger in the brain until sleep makes them permanent.

Ultrasound Therapy Boosts Cognition in Alzheimer’s Disease

Researchers from UQ's Queensland Brain Institute have found that targeting amyloid plaque in the brain is not essential for ultrasound to deliver cognitive improvement in neurodegenerative disorders.

Long-Term Memory Formation Requires Nerve Cell Damage

A new study published in Nature puts a different spin on inflammation’s role in the brain, one that could have implications for drugs that target inflammatory pathways.
A living-tissue model developed by Dartmouth researchers showed that a fatal trauma killed younger oligodendrocytes.

Brain Cells Unexpectedly Linger Before Their Death

For oligodendrocytes–the central nervous system cells critical for brain function–age may not bring wisdom, but it does come with the power to cling to life for much, much longer than scientists knew. That’s according to a new study.
