Implant-derived metals found in cerebrospinal fluid
Research led by Charité–Universitätsmedizin Berlin has found that metal particles from artificial joint implants can enter the central nervous system and accumulate in cerebrospinal fluid, raising concerns about potential ...
Dopamine neurons that fuel overeating may weaken effectiveness of obesity medication
Delicious and extremely palatable food can increase the tendency of hedonic eating, where one consumes food for the sole purpose of deriving pleasure instead of the body's energy needs. Hedonic eating often leads to eating ...
Vision restored: Retinal therapy research marks first successful induction of long-term neural regeneration
Vision is one of the most crucial human senses, yet more than 300 million people worldwide are at risk of vision loss due to various retinal diseases. While recent advancements in retinal disease treatments have successfully ...

Wearable brain stimulation device could make on-the-go therapeutics a reality
Researchers at the Institute of Automation of the Chinese Academy of Sciences have developed a compact, battery-powered brain stimulation device capable of delivering therapeutic magnetic pulses while a person is walking ...
How perceptions are influenced by expectations: Songbird study draws parallels with human speech processing
Past neuroscience and psychology studies have shown that people's expectations of the world can influence their perceptions, either by directing their attention to expected stimuli or by reducing their sensitivity (i.e., ...
Brain-to-voice interface converts thoughts to speech in near-real time
Marking a breakthrough in the field of brain-computer interfaces (BCIs), a team of researchers from UC Berkeley and UC San Francisco has unlocked a way to restore naturalistic speech for people with severe paralysis.

What drives our cravings for food and drink? Neurons in the amygdala may play a key role
To ensure we get the calories and hydration we need, the brain relies on a complex network of cells, signals, and pathways to guide us when to eat, drink, or stop. Yet, much about how the brain deciphers the body's needs ...
