Brainwaves
A new study published in Nature Neuroscience has shown that neuromodulation of low-frequency neuronal activity in the parietal cortex improved working memory, while high-frequency modulation in the prefrontal cortex improved long-term memory in older adults [1]. As people age, their cognitive abilities get worse. This includes memory decline, which might dramatically impact quality of life....
Mouse maze
A new study published in Neurobiology of Aging has shown that neither caloric restriction nor intermittent fasting improve late-life cognition in genetically diverse mice, but the effect depends on genetic composition [1]. Eat less, think better? Dietary interventions are known to have potential to extend lifespan and delay age-associated diseases, at least in animal models....
Blood vessels brain
Researchers publishing in Aging have found that enlarged perivascular spaces (ePVS) in the brain are correlated with vascular disorders [1]. These spaces, which are part of the brain's glymphatic system, allow for the drainage of potentially dangerous metabolites such as beta amyloid [2]. A known biomarker of brain disorders As they become enlarged, perivascular spaces...
brain vasculature
Researchers publishing in GeroScience have reported that the age-related decline in IGF-1 levels is associated with neurovascular aging [1]. IGF-1 and brain vasculature BrainThe brain is perhaps the most important organ in the body. While many organs are critical to our survival, the brain contains the self. It is responsible for personality and consciousness and...
Astrocyte
A new study published in Stem Cell Research and Therapy has shown that rejuvenating the astrocyte niche in the aged brains of mice leads to improved nervous system function at both the cellular and organismal levels [1]. A glia-centric approach In brain aging, neurons are quite literally only half of the story; the other half...
Oligodendrocytes
Scientists have found that infusing old mice with cerebrospinal fluid obtained from young mice improves their memory by increasing proliferation and differentiation of oligodendrocyte progenitor cells (OPCs) [1]. The fountain of brain youth It has been known for years that blood from young animals can alleviate or even reverse some age-related changes, including cognitive changes,...
