Brain neurons re-entering the cell cycle age quickly and shift to senescence, particularly in neurodegenerative disease
Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study published April 9 in the open-access journal ...

Consumption of contaminated venison suspected in cases of deer hunters with prion disease
A small team of medical workers and researchers in the U.S. has published a case study of two men, both deer hunters, who developed a rare prion disease. In their study, published in the journal Neurology, the group describes ...
Charting brain synchronization patterns during social interactions
We experience the world and connect with others through social interactions. Engaging in activities, such as conversations, cooperative tasks, and intimate relationships, deeply affect brain activity leading to coordinated ...

Neuroscientists report a distinct role of touch receptors in treating chronic pain
People often experience the phenomenon of injuring a hand and feeling relief from vigorously shaking it. The mechanism behind this effect is fairly well explained by the "gate control theory" of Melzack and Wall, but it is ...
Stress activates brain regions linked to alcohol use disorder differently for women than men, finds study
When exposed to stress, people with alcohol use disorder engage parts of the brain associated with both stress and addiction, which may cause them to drink or crave alcohol after a stressful experience, suggest the authors ...
