Adding new channels to the brain remote control

By enabling super-fast remote control of specific cells, light-activated proteins allow researchers to study the function of individual neurons within a large network—even an entire brain. Now one of the pioneers of 'optogenetics' ...

Dopamine primes the brain for enhanced vigilance

Imagine a herd of deer grazing in the forest. Suddenly, a twig snaps nearby, and they look up from the grass. The thought of food is forgotten, and the animals are primed to respond to any threat that might appear.

Neuroscience

Is foraging behaviour regulated the same way in humans and worms?

How does our nervous system motivate us to get off the sofa and walk to the fridge, or even to the supermarket, to get food? A research team led by Alexander Gottschalk from Goethe University investigated this using the threadworm ...

Neuroscience

Synapse 'protection' signal found; helps to refine brain circuits

The developing brain is constantly forming new connections, or synapses, between nerve cells. Many connections are eventually lost, while others are strengthened. In 2012, Beth Stevens, Ph.D. and her lab at Boston Children's ...

Paralyzed mice with spinal cord injury made to walk again

Most people with spinal cord injury are paralyzed from the injury site down, even when the cord isn't completely severed. Why don't the spared portions of the spinal cord keep working? Researchers at Boston Children's Hospital ...

Light based cochlear implant restores hearing in gerbils

A team of researchers with members from a variety of institutions across Germany has developed a new type of cochlear implant—one based on light. In their paper published in the journal Science Translational Medicine, the ...

Neuroscience

Defining the brain mosaic in fruit flies and humans

Similar to a mosaic floor where different patterned tiles come together to make a composite and holistic image, our brains consist of billions of unique neurons that connect and generate coordinated brain activity. Unlike ...

HIV & AIDS

HIV lies dormant in brain, increasing risk of dementia, but how?

The HIV virus, which causes AIDS, has long been known to target and disable cells of the immune system, which are responsible for fighting off invading microorganisms and for suppressing malignant cancers. More recently, ...
