A groundbreaking study by UCSF researchers has pinpointed the protein FTL1 as a key contributor to age-related cognitive decline, particularly affecting the hippocampus. Elevated FTL1 levels in older mice correlated with diminished brain cell connections and impaired cognitive function. Remarkably, reducing FTL1 in aged mice reversed these effects, boosting memory and neural connections. Aging is often accompanied by a decline …

The Healthy Brain Aging Initiative was developed by Tulane’s Neurology Chair, Dr. Demetrius Maraganore, in response to the notably high incidence of Alzheimer’s disease and dementia in Louisiana. The research from this program is focused on Alzheimer’s and dementia prevention and memory disorder treatments using the latest evidence-based research and movement disorders treatment, like Parkinson’s, related to brain aging. Maraganore, …

Immune cells in the human brain may be critical to orchestrating the organ’s development in the womb because they trigger a dramatic increase in an important type of nerve cell, new research suggests. Estimates suggest that these key cells, known as inhibitory interneurons, make up some 25% to 50% of the neurons in the adult cortex, the wrinkled tissue that …

Alexa Ray Joel shared an update on her father Billy Joel’s health as the legendary singer battles a brain disorder. Billy, 76, announced that he had been diagnosed with normal pressure hydrocephalus (NPH) – which affects his vision, hearing and balance – on social media in May. The “Riverside Way” singer, who is the daughter of Billy and his ex-wife, …

Noland Arbaugh, the first person to get a brain chip implant by Elon Musk’s Neuralink, has shared how the new technology has transformed his life 18 months after the surgery. Notably, Arbaugh had dislocated two of his vertebrae during a swimming accident in 2016 and thereafter lost sensation and movement below his shoulders. Arbaugh had received the implant in 2024, …

B for brain, B for B-complex!As Phoebe would have pointed out, ‘coincidence’?Scientific evidence suggests it’s definitely not!Emerging research shows that beyond the well-known B6 and B12, the full vitamin B-complex, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B7 (biotin), and B9 (folate), plays vital roles in keeping your brain energized and resilient. Studies reveal that these B …

Scientists are making significant strides forward in brain-computer interface (BCI) technology, and a newly developed system can translate our thoughts into text or sound. It’s essentially an inner speech decoder, developed by researchers from institutions across the US. In tests on four volunteers with severe paralysis, the decoder hit an accuracy rate of up to 74 percent in translating thoughts …

You might expect that with age comes a natural progression of brain degeneration, but new research shows that this might not be the case for all regions of the brain. A new analysis of mouse and human brains suggests that some parts of the somatosensory cortex – the part of the brain that processes sensory information – aren’t just exempt …

Even years after a person has lost an arm, the brain faithfully maintains the circuits that once controlled the missing limb. MARY LOUISE KELLY, HOST: When someone loses an arm, they can see it’s gone, but a new study finds their brain keeps on trying to interact with the missing limb. NPR’s Jon Hamilton reports on a study that challenges …

Summary: A new study identifies brain area 46 in the marmoset dorsolateral prefrontal cortex as a key regulator of mood-related behavior. When this region was inactivated, the animals showed less interest in rewards and heightened sensitivity to threats, mimicking depression and anxiety symptoms. Researchers also discovered a functional network connecting areas 46, 32, and 25 that helps counterbalance these effects, …
