With a mouth like a whirlpool full of teeth, the lamprey is not something you'd normally want anywhere near your brain. But now, researchers from the Universities of Texas and Wisconsin-Madison have used molecules taken from the freaky fish's immune system to deliver drugs inside the body – and even managed to sneak them into the brain...

An intriguing new study, led by scientists from the University of Glasgow, suggests there is a direct causative link between eating a high-fat diet and the development of depression. The new research demonstrates how certain dietary fats can enter the brain, disrupt specific signaling pathways in the hypothalamus, and subsequently induce signs of depression...

I was a 45-year-old photographer living in Santa Fe, New Mexico, when my world flipped upside down. In November 2014, I was diagnosed with brain cancer. It was aggressive and extremely rare, and it grew larger despite the doctor’s attempts with steroids. By mid-December, I was already in the hospital, unable to walk or talk. The tumor was inoperable… until I became non-responsive and my opt
A new imaging technique designed to help surgeons identify the location of malignant brain tumors during surgery is showing promising early clinical trial results. The technique combines a new high-sensitivity near-infrared camera with a special imaging agent synthesized from an amino acid found in scorpion venom. ..

Scientists have developed an implant that interprets signals in the brain and converts them into understandable, synthesized speech. This innovative piece of technology could one day give a voice to people otherwise unable to communicate...

Researchers at Northwestern University have used a non-invasive form of magnetic brain stimulation to improve the memory of older adults. After just five short sessions the older adults scored as well as a younger cohort on a variety of memory tasks...

In a breakthrough study, researchers have managed to restore some brain function in pigs as long as four hours after death. Using a system that pumps preserving chemicals through the brain's circulatory system, the team not only staved off cell death but actually restored some functions like synaptic activity. The astounding discovery raises some ethical questions and may spark new debate
Though it is already administered in off-label doses at clinics across the US for its rapid anti-depressant effects and, significantly, was approved in nasal spray form by the FDA last month, there remains a lot to learn about ketamine and its close chemical relatives. A new study has shed more light on how it can stave off depressive symptoms, with experiments on mice revealing how it rep
From treating depression to curtailing the effects of Parkinson's disease to awakening patients in a vegetative state, stimulating the brain with electrical currents holds all kind of potential. One very promising branch of this research centers on arresting cognitive decline by boosting memory and learning, and a string of recent studies have uncovered its exciting potential in this regar
