The method, dubbed “DIANA,” could transform neuroscientists’ understanding of how the brain works, researchers say—though for now, it’s only been tested in anesthetized mice.
A new technique reveals cells’ precise locations and functions in the brain. Its developers have already used it to identify a previously unknown neuron type.
A research group argues that a species’ number of neurons, rather than brain volume, should serve as indicator of cognitive capacity when studying brain evolution, but some experts voice doubts.
The National Academies’ report touches on ethical issues raised by new technologies such as brain organoids and human-animal chimeras, and suggests that current regulatory oversight is sufficient.
A study has sparked controversy by suggesting that cells made using a popular lab protocol have been misidentified, with potentially serious repercussions for brain research. Critics say the significance of the findings has been overstated.
The animals adopt the emotional state of their cagemates, and the parts of the brain engaged during the process are different for pain and fear, according to a new study.
An imaging agent reveals aggregated tau protein in the brain during PET scans and could improve the diagnosis of neurodegenerative diseases, particularly tauopathies.
In a first-of-its-kind study, researchers monitored subsecond changes in levels of the neurotransmitters in the human brain, unlocking new insight into their function.
A nascent but growing consumer market for brain-computer interface technology is driving the development of sleek new tools for decoding brain activity.
New studies show that elevated levels of a form of tau called p-tau217 can accurately distinguish Alzheimer’s disease from other forms of dementia, and perhaps even predict it.
The California-based company Humm has developed a “bioelectric memory patch” to improve working memory, but some experts question the efficacy of the device.
A combination of videography, machine learning, and brain imaging has identified facial expressions and neural activity patterns in mice that are associated with their emotions.
