Neuroimaging – News and Features

A study using brain imaging in mice reveals that the anterior cingulate cortex (ACC) encodes empathic responses to others' pain. ACC neurons projecting to the periaqueductal gray (PAG) drive affective empathy.

Scientists at St. Jude Children’s Research Hospital have used positron emission tomography (PET) with edaravone, a drug used to treat ALS, to detect oxidative stress, which leads to brain damage.

Oregon Health & Science University researchers have found that consuming cannabis while pregnant could affect fetal lung development and function, potentially leading to the development of chronic respiratory health conditions.

A study from Mass General Brigham found that women over 70 who used menopausal hormone therapy (HT) more than a decade earlier accumulated tau, a key Alzheimer’s marker, at a faster rate. The findings highlight the importance of timing in HT use.

In this interview, Technology Networks spoke with Dr. Gilad Evrony, assistant professor at NYU Grossman School of Medicine, to learn more about a novel tool for rapidly identifying cancer cells in the operating room.

A study of nearly 500,000 adults found that short sleep is linked to depression and brain loss in emotional regions, while long sleep is associated with cognitive decline and degenerative diseases.

Researchers found that sleep spindles, brief bursts of brain activity, may predict recovery in unresponsive brain injury patients. Patients with these waves were more likely to regain consciousness and functional independence.

Short-term intake of high-calorie foods can alter insulin sensitivity in the brain, which may be an initial cause of diabetes and obesity.

Researchers have applied a novel reaction to peptides produced using cell-free translation systems, providing a fast and efficient route to dehydrophenylalanine-containing structures.

A study of nearly 37,000 adults suggests that raising children strengthens neural connections, slowing brain aging. The effect increases with each additional child and was observed in both mothers and fathers.
