Ever felt tired and sluggish after eating sugar or a startling number of ginormous meals? That’s the effects of a sugar crash, which researchers at New Zealand have shown can impair cognitive performance – in a double-blind, placebo-controlled study.
Sleep is so good for memory because it strengthens new and old versions of the same memory to similar extents, according to new study. Instead of overwriting the old version of the memory, the brain generates and stores multiple (new and old) versions of the same experience, helping you use your memory in the most flexible and adaptable way.
A new study by researchers from the University of British Columbia and researchers in China indicates that Alzheimer’s disease could originate in parts of a body other than the brain.
Scientists have used magnetic nanoparticles to directly control physical movements of mice. Using a technique called Magneto-Thermal Stimulation, researchers activate sections of the brain that cause mice to run, rotate or lose control of the extremities.
Depression can lead to permanent changes in the structure of the brain. In a study conducted at the University of Edinburgh, researchers found alterations in parts of the brain known as white matter – the key component of the brain and spinal cord consisting mainly of nerve fibres. White matter is critical for normal functioning of the brain, and its disruption has been linked to problems with emotion processing and thinking skills.
Scientists have created perfect replicas of human faces that were shown to monkeys just from recording the animal’s brain signals. This has solved one of the most intractable problems in neuroscience – "how the brain recognizes faces."
Chronic sleep deprivation can cause the brain to start eating itself, according to study at the Marche Polytechnic University in Italy. Astrocytes are cells in our brain that destroy and digest worn-out cells and debris, but researchers studying the brain of mice have found that these cells go into overdrive when the animals are chronically sleep-deprived, destroying more of the brain's neural connections.
Virtual reality has become an increasingly popular idea—allowing you to explore other worlds, and even altering your own. But in the world of addiction treatment, VR is a hot new topic, and a tentative new method of controlling triggers, cravings and urges.
Working memory is an aspect of brain function that stores bits of information for short-term use. It is the part of memory that helps us remember directions to a location, a phone number before dialing, or a mental list of items to pick up at the grocery store.
