A novel marker of adult human neural stem cells discovered

The mammalian center for learning and memory, hippocampus, has a remarkable capacity to generate new neurons throughout life. Newborn neurons are produced by neural stem cells (NSCs) and they are crucial for forming neural ...

Putting a protein into overdrive to heal spinal cord injuries

Using genetic engineering, researchers at UT Southwestern and Indiana University have reprogrammed scar-forming cells in mouse spinal cords to create new nerve cells, spurring recovery after spinal cord injury. The findings, ...

Reactivating aging stem cells in the brain

As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers at the University of Zurich have now discovered a mechanism linked ...

Neuroscience

Study sheds light on molecular underpinnings of long-term memory

On a late summer day in 1953, a young man who would soon be known as patient H.M. underwent experimental surgery. In an attempt to treat his debilitating seizures, a surgeon removed portions of his brain, including part of ...

New drug pathway linked with tuberous sclerosis

Tuberous sclerosis complex (TSC) is a neurological disorder causing non-cancerous tumors, called cortical tubers, to grow throughout the brain and body, as well as other conditions like epilepsy and autism. While medications ...

Neuroscience

Neurons thrive even when malnourished

When animal, insect or human embryos grow in a malnourished environment, their developing nervous systems get first pick of any available nutrients so that new neurons can be made.

Why does coronavirus make people lose their sense of smell?

To begin with, it was just anecdotal reports. Ear, nose and throat specialists from around the world were sharing their experiences on online message boards—they were all seeing a spike in patients experiencing anosmia, ...

Neuroscience

Alzheimer research: Noise-inducing neurons shut down memories

Neurons that are responsible for new experiences interfere with the signals of neurons that contain memories and thereby disturb the recall of memories—at least in mice. The research group of Martin Fuhrmann of the German ...
