You probably don't think of ice cream as a pain-inducing substance, but enjoying those first few spoonfuls of the frozen treat too quickly might bring on a sudden, stabbing pain in the forehead known as "brain freeze." The pain of brain freeze can begin within seconds of being exposed to cold temperatures, and the intensity of the pain peaks very quickly, often within seconds, said Dr. Stephanie Goldberg, a neurologist and headache specialist at Tufts Medical Center in Boston. Why do you get it? Brain freeze, also called an "ice-cream headache," is known in medical terms as a "cold-stimulus headache," Goldberg said. It's a common phenomenon that affects people of all ages, but doctors aren't quite sure why it happens. [Ouch: 10 Odd Causes of Headaches] For this type of headache, the main trigger is any kind of exposure to a significantly cold temperature, Goldberg said. It's not only caused by an internal trigger, like eating frozen treats too quickly; it can also be caused by an … [Read more...] about What Is Brain Freeze?
Where is brain located
Your brain forms new memories all the time — and your gut might help that happen. The gut-brain connection is mostly known for its role in controlling the amount of food we eat, with the gut signaling to the brain when we've had enough. But a new study published June 5 in the journal Nature Communications suggests that the gut-brain connection may also play an important role in forming memories about where places and objects are located in our environment. The new study was done in rats, but the findings could translate to humans, said senior study author Scott Kanoski, an assistant professor of biological sciences at the University of Southern California. [10 Things You Didn't Know About the Brain] The gut and the brain mainly communicate through the vagus nerve, the body's longest nerve. In the new study, the researchers wanted to test what would happen in rats if parts of this nerve were cut so that it could no longer send signals from the gut to the brain. Because this … [Read more...] about Your Gut Remembers Where You Had a Good Meal
Update May 29th 11:40AM ET: This article was originally published on March 16, 2017 and has been updated to include video. Weird as it might sound, there are competitive rememberers out there who can memorize a deck of cards in seconds or dozens of words in minutes. So, naturally, someone decided to study them. It turns out that practicing their techniques doesn't just improve your memory — it can also change how your brain works. There’s been a long-standing debate about whether memory athletes are born with superior memories, or whether their abilities are due to their training regimens. These tend to include an ancient memorization strategy called the method of loci, which involves visualizing important pieces of information placed at key stops along a mental journey. This journey can be an imaginary walk through your house or a local park, or your drive to work. The important thing is that you can mentally move back through it to retrieve the pieces of information you … [Read more...] about An ancient memorization strategy might cause lasting changes to the brain

For years, Kendra Jackson battled an incessantly runny nose — sniffling and sneezing, blowing and losing sleep each night. Jackson said she initially thought she was getting a cold, then, as her symptoms persisted, doctors suggested it was possibly seasonal allergies, … [Read more...] about She was told her perpetually runny nose was from ‘allergies.’ It was a brain-fluid leak.
Klas Tybrandt, principal investigator at the Laboratory of Organic Electronics at Linköping University, has developed new technology for long-term stable neural recording. It is based on a novel elastic material composite, which is biocompatible and retains high electrical conductivity even when stretched to double its original length. The result has been achieved in collaboration with colleagues in Zürich and New York. The breakthrough, which is crucial for many applications in biomedical engineering, is described in an article published in the prestigious scientific journal Advanced Materials. The coupling between electronic components and nerve cells is crucial not only to collect information about cell signalling, but also to diagnose and treat neurological disorders and diseases, such as epilepsy. It is very challenging to achieve long-term stable connections that do not damage neurons or tissue, since the two systems, the soft and elastic tissue of the body and the … [Read more...] about Capturing Brain Signals With Soft Electronics
