New experiences enhance learning by resetting key brain circuit

A study of spatial learning in mice shows that exposure to new experiences dampens established representations in the brain’s hippocampus and prefrontal cortex, allowing the mice to learn new navigation strategies.

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 have now discovered a mechanism linked to stem cell aging – and how the production of neurons can…

Signal coupling between neuron-glia super-network may lead to improved memory formation

Scientists have revealed glial cells act as amplifiers for synaptic signals and artificial control of the glial state can potentially be used for enhanced memory function of the brain.

Seeing schizophrenia: X-rays shed light on neural differences, point toward treatment

An international research team used the ultrabright X-rays of the Advanced Photon Source to examine neurons in the brains of schizophrenia patients. What they learned may help neurologists treat this harmful brain disorder.

ALS neuron damage reversed with new compound

Scientists have identified the first compound that eliminates the ongoing degeneration of upper motor neurons that become diseased and are a key contributor to ALS (amyotrophic lateral sclerosis), a swift and fatal neurodegenerative disease that paraly…

Beta blockers can repair malformed blood vessels in the brain

Propranolol, a drug that is efficacious against infantile haemangiomas (‘strawberry naevi’, resembling birthmarks), can also be used to treat cerebral cavernous malformations, a condition characterized by misshapen blood vessels in the brain and elsewh…

Seasonal variation in daylight influences brain function

A research group has studied how seasons influence the function of the brain. Researchers showed that the length of daylight affects the opioid receptors, which in turn regulates the mood we experience.

Sleep is vital to associating emotion with memory, study finds

When you slip into sleep, it’s easy to imagine that your brain shuts down, but new research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain.

Lonely adolescents are susceptible to internet addiction

Loneliness is a risk factor associated with adolescents being drawn into compulsive internet use. The risk of compulsive use has grown in the coronavirus pandemic: loneliness has become increasingly prevalent among adolescents, who spend longer and lon…

Scientists repair injured spinal cord using patients’ own stem cells

Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers report.
