Intravital brain imaging is a powerful method for observing neurons, glial cells, and their surrounding environments in living animals. It facilitates the study of neurological diseases, drug efficacy ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. Billions of nerve cells send signals coursing through our bodies, serving as conduits ...

The vagus nerve connects the brain to major organs throughout the body and plays important roles in many bodily functions. For people with mobility issues participating in physical therapy, ...

Researchers at Stanford University and Harvard Medical School have developed tiny and ultra-flexible mesh neural probes that can be implanted into sub-100-micrometer-scale blood vessels in the brains ...

The hypoglossal nerve is one of the 12 cranial nerves arising from the brain. It's a paired nerve, and you have two — left and right. Together, the two hypoglossal nerves control the muscles of the ...

Scientists have developed a novel concept of a nose-to-brain system for the clinical application of neuropeptides. They developed a derivative of glucagon-like peptide-2 and found that when ...

In a recent study published in the journal Nature Medicine, researchers examine clinical glioblastoma and benign intracranial samples to determine the presence and function of immune cells in the ...
