  • How the brain learns that earmuffs are not valuable at the beach
    on January 21, 2021 at 6:17 pm

    Fast-spiking neurons in the basal ganglia allow monkeys to associate different values with the same objects based on the surrounding environment. Blocking input from these cells inhibited learning of new scene-based values, but did not erase already learned associations. This could help understand clinical conditions such as Tourette syndrome, which is characterized by reduced input from these cells.

  • Eye tests predict Parkinson’s-linked cognitive decline 18 months ahead
    on January 19, 2021 at 3:28 pm

    Simple vision tests can predict which people with Parkinson’s disease will develop cognitive impairment and possible dementia 18 months later, according to a new study. In a related study, the researchers also found that structural and functional connections of brain regions become decoupled throughout the entire brain in people with Parkinson’s disease, particularly among people with vision problems.

  • Scientists identify nutrient that helps prevent bacterial infection

    Scientists studying the body’s natural defenses against bacterial infection have identified a nutrient — taurine — that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding could aid efforts seeking alternatives to antibiotics.

  • Could altering mealtimes prevent development of Type 2 diabetes?
    on January 15, 2021 at 4:03 pm

    An innovative new study is set to examine if changing our mealtimes to earlier or later in the day could reduce the risk of developing Type 2 diabetes.

  • A rift in the retina may help repair the optic nerve
    on January 14, 2021 at 2:57 pm

    In experiments in mouse tissues and human cells, researchers say they have found that removing a membrane that lines the back of the eye may improve the success rate for regrowing nerve cells damaged by blinding diseases.
