Researchers at Trinity College Dublin studying the factors influencing healthy brain aging in Latin American and Caribbean (LAC) countries find the lessons learned there, can also be applied to home.

Immune cells in the brains of people who had Alzheimer’s disease appear to behave differently than those who had healthy brains for their age, according to an analysis of the cells’ gene activity. The finding suggests it might be possible to treat Alzheimer’s disease by altering the behavior of these cells.

The longer a person has type 2 diabetes, the more likely they may be to experience changes in brain structure, a new study finds.

Using human “mini-brain” models known as organoids, scientists have discovered that the roots of autism spectrum disorder may be associated with an imbalance of specific neurons that play a critical role in how the brain communicates and functions. The specific cells are known as excitatory cortical neurons.

Psilocybin, the active ingredient in psychedelic mushrooms, shows promise for the transitional treatment of episodic migraines in early clinical trials, according to a recent review.

Researchers have discovered that a neural marker of error detection in the brain’s visual system previously considered pre-attentive may actually require attention and that subtle visual irregularities may be revealed by other neural markers.

A new study has demonstrated that self-organization of neurons as they learn follows a mathematical theory called the free energy principle.

The neural network related to speech is mostly located in the left cerebral hemisphere, while singing has been primarily associated with the structures of both hemispheres. However, a new study indicates that the left hemisphere has a greater significance, including in terms of singing, than previously thought.

A new digital headset designed to measure alterations in brain function could change decisions about how quickly an athlete is ready to return to play after a concussion.

A new study suggests stimulating the sense of smell can boost memory. Older adults exposed to odors while they slept performed better on verbal memory tests and showed improved function in a brain pathway that supports memory formation, according to the study, published in the journal Frontiers in Neuroscience.

Finally this week, researchers have shown that machine learning can accurately predict subtypes of Parkinson’s disease using images of patient-derived stem cells.
