Aging is particularly harsh on the hippocampus — the brain region responsible for learning and memory. Now, researchers at UC San Francisco have identified a protein that’s at the center of this decline. They looked at how the genes and proteins in the hippocampus changed over time in mice and found just one that differed between old and young animals. …

Postdoctoral researcher Erin Kunz holds up a microelectrode array that can be placed on the brain’s surface as part of a brain-computer interface. Jim Gensheimer hide caption toggle caption Jim Gensheimer Surgically implanted devices that allow paralyzed people to speak can also eavesdrop on their inner monologue. That’s the conclusion of a study of brain-computer interfaces (BCIs) in the journal …

Animal models The following mouse lines were used: C57BL/6J mice (The Jackson Laboratory, line 000664), C57BL/6 aged mice (National Institutes of Aging) and B6;129-Gt(ROSA)26Sortm1(CAG-cas9*,-EGFP)Fezh/J (The Jackson Laboratory, line 024857). All studies were done in young (2–3 months) or aged (18–22 months) male mice that were not involved in any previous procedures. The numbers of mice used to result in statistically significant differences …

Scientists have developed a brain-computer interface that can capture and decode a person’s inner monologue. The results could help people who are unable to speak communicate more easily with others. Unlike some previous systems, the new brain-computer interface does not require people to attempt to physically speak. Instead, they just have to think what they want to say. “This is …

The results held steady for up to three months after the stimulation and coaching ended. “One person had 3,000 daily steps in the beginning of the study, but she improved to 10,000 steps in the end,” said On-Yee Lo , an assistant scientist at the Hinda and Arthur Marcus Institute for Aging Research at Hebrew SeniorLife, and the study’s lead …

Scientists have revealed that immune cells in Alzheimer’s brains behave differently from those in brains of people without the disease – a discovery that could lead to new treatments. Published in 2023, an analysis of human brain tissue discovered microglia in the brains of people with Alzheimer’s were more frequently in a pre-inflammatory state, making them less likely to be …

Postdoctoral scholar Erin Kunz holds a microelectrode array. Surgically implanted in the brain’s surface layer, the array records neural activity patterns directly from the brain to a computer.

But what happens when machines can hear …

Chinese scientists have found a way to turn human stem cells into dopamine-producing brain cells, transplanting them into mice and helping reduce depressive behaviour and boost pleasure. When the engineered neuron-like cells were grafted into depression-model mice, they helped lessen symptoms like anxiety and resignation while increasing feelings of enjoyment. The development has the potential to be employed as a …

Chinese scientists have developed a technology that can make organs such as the brain or the heart transparent, allowing an exceptionally clear view of their inner workings. The new method produced “highly accurate and vivid” 3D images of organs by preserving the integrity of their biological structures and enhancing the brightness of the fluorescent dyes scientists use to highlight cells …
