Neurodegenerative disease found in monkeys

Scientists have discovered a naturally occurring disease in monkeys that mimics a deadly childhood neurodegenerative disorder in people — a finding that holds promise for developing new gene therapies to treat Batten disease. Scientists confirmed thro…

Leopard geckos can make new brain cells

Researchers have discovered the type of stem cell allowing geckos to create new brain cells. This finding provides evidence that lizards may also be able to regenerate parts of the brain after injury.

Mass hysteria: An epidemic of the mind?

Mass hysteria is a highly controversial phenomenon that has been documented since the Middle Ages. In this Spotlight, we investigate how it can manifest.

How a cat parasite can change your personality

A new study finds a link between being infected with the parasite Toxoplasma gondii and displaying riskier, more entrepreneurial behavior.

The big picture: Mouse memory cells are about experience, not place

When it comes to memory, it’s more than just ‘location, location, location.’ New research suggests that the brain doesn’t store all memories in ‘place cells,’ the main type of neuron in the hippocampus, a structure crucial for navigation and memory. In…

Electricity sparks neuronal diversity during brain development

To understand how neuronal circuits emerge during development, researchers investigated what enables neuronal stem cells to generate successive subtypes of neurons as the embryo grows. By measuring the electrical activity, they found that membrane volt…

Can scientists leverage mysterious mossy cells for brain disease treatments?

Scientists showed that ‘mossy cells’ in the hippocampus regulate local stem cells to control their production of new neurons, which is important for normal learning and memory, stress response, and mood regulation. Such neurogenesis in the adult brain …

Traumatic brain injury: Discovery of two molecules could lead to new drug treatments

After 10 years of research, a team of scientists has identified two molecules that protect nerve cells after a traumatic brain injury and could lead to new drug treatments. The molecules promote full recovery after traumatic brain injury (TBI) in mice.

Neurobiology: Finding one’s way home

The otic placode gives rise to the inner ear in vertebrates. A new study shows that even when it is transplanted to ectopic positions, the nerve cells that grow out of the transplanted ear can form functional connections in the brain.

Cancer cells destroyed with two antipsychotic drugs

A new study shows that the antipsychotics perphenazine and fluphenazine can successfully destroy cancer cells in cell cultures and rodents.
