Scientists at Johns Hopkins have developed a new spinal stimulator that can help restore lower limb function to paralyzed patients. The tiny device can be non-invasively implanted through a syringe.

New research is the first to reveal microstructural brain changes in long COVID patients compared to fully recovered patients and uninfected subjects. The findings indicate long COVID symptoms can be associated with changes to specific cerebral networks.

It's been called plain and boring, but this Thescelosaurus species has now had its sad reputation upended, thanks to fascinating sensory discoveries that suggest it lived a unique, successful life underground, beneath the feet of its fearsome predators.

Love it or hate it, this punchy Japanese condiment has many scientists very interested in its cognitive health-boosting abilities. A new study of 60-80-year-olds supports the growing evidence – and you don't even need to taste it to reap the benefits.

In a fascinating new study, scientists have for the first time uncovered the heart-brain pathway, fueled by specific over-excited sensory neurons, that triggers fainting. The discovery is a huge step towards targeted treatments for a host of conditions.
-
We know chronic poor sleep is bad for your health but for decades scientists have reported a strange phenomenon where acute sleep deprivation actually leads to elevated mood so a team of researchers set out to investigate this odd physiological sensation.
-
Administering general anesthesia is a tricky business, as you don't want to under- or overdo it. With that quandary in mind, scientists have now developed an automated system that continuously adjusts the dosage, based on the patient's brain waves.

Scientists have found the molecular mechanism that causes a losing zebrafish to wave the white flag. While fighting fish in general may not spark a lot of interest, their shared neurobiology with humans means this could be a very significant discovery.
-
While its movements are slow and gentle, Tai Chi is actually a martial art. Now, a study shows that it can not only help people learn movements grounded in self defense, but it can also help them fight the symptoms of Parkinson's Disease.
-
For the first time, scientists have identified how the region of our brain that powers memory is made up of two very different sets of neurons: one that deals with previous associations, and one that is predictive, actively shaping future behaviors.
-
A new kind of high-frequency deep-brain stimulation has successfully stimulated neurons in the hippocampus, the region that forms, organizes and retrieves memories. This non-invasive, painless treatment is now being trialed on dementia patients.
-
Using a new kind of neuroimaging tool, researchers have uncovered evidence to help explain how antidepressant medications work, and why they take so many weeks to kick in.
