New insight into how protein TDP-43 affects gene expression in ALS and FTD
Neurodegenerative diseases, such as Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are medical conditions characterized by the progressive degradation of cells in the brain, ...
Prototype device restores lost smell by teaching the brain to feel odors
There is new hope for people who have lost their smell. Scientists have successfully tested a breakthrough device that lets people detect the presence of certain odors. This innovative system helps them "smell" again by translating ...
Inhibitory neurons in the amygdala can flexibly shape emotional learning and memory
Neurons that specifically reduce and modulate electrical brain activity have a greater influence on emotional memories than previously thought. DZNE researchers came to this conclusion based on studies in mice. A team led ...

Specific brain activity patterns predict greater control over drinking behavior, study finds
Alcohol use disorder (AUD) is among the most widespread substance use disorders (SUDs) worldwide, characterized by an impaired ability to control the intake of alcohol. For many years, psychologists and psychiatrists have ...
Targeted ultrasound can shape the brain's reward-seeking mechanisms
The nucleus accumbens is a tiny element of the human brain triggered when we experience something enjoyable, and used to help us learn behaviors that lead to rewards. A new study has shown for the first time that its influence ...
