This question is raised by one of the TCCI Neurochat 2021 speakers. We are continuously collecting questions from young scientists all over the world. We will explore insightful answers with leading experts. Please pay attention to our website and WeChat platform (nextquestion)!

Injury or disease that afflicts a relatively small number of brain cells causes a chain reaction that stops activity across a vast network of neural circuits, according to new research from Oregon Health & Science University. The findings, published today in the journal Neuron, may help to explain why people can suffer from temporary but […]

A recent proposal called the Scaffolding Theory of Cognitive Aging (STAC) postulates that functional changes with aging are part of a lifespan process of compensatory cognitive scaffolding that is an attempt to alleviate the cognitive declines associated with aging. Indeed, behavioral studies have shown that aging is associated with both decline as well as preservation […]

A new study published in Current Biology identifies the biological triggers that promote quicker nerve regeneration. From their previous studies, the researchers knew that damaged nerves regrow more quickly when “stress granules” in the site of the nerve injury are broken apart. Now they know what causes those stress granules to disassemble through a process […]

Spinal cord injury often leads to permanent functional impairment. In a new study published in the journal Science researchers at Karolinska Institutet show that it is possible to stimulate stem cells in the mouse spinal cord to form large amounts of new oligodendrocytes, cells that are essential to the ability of neurons to transmit signals, […]

A world-first study has found that severely overweight people are less likely to be able to re-wire their brains and find new neural pathways, a discovery that has significant implications for people recovering from a stroke or brain injury.

Stimulating the nervous system using small electric current by acupuncture could tamp down systemic inflammation in the body, suggests new research in mice from a team of neuroscientists in the U.S. and China. The research, publishing August 12 in the journal Neuron, helps to map the neuroanatomical underpinnings of this ancient medical practice.
