Study Shows Multitasking May Change Brain Structure

New research from the University of Sussex shows that people who frequently use several media devices at the same time have lower grey-matter density in one particular region of the brain compared to those who use just one device occasionally. Simultaneously using mobile phones, laptops and other media devices could be changing the structure of […]

Neuroscientists Reverse Emotional Association of Memories

Neuroscientists from MIT have identified the brain circuit that controls how memories become linked with positive or negative emotions, revealing that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics. Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach […]

Researchers Show Regular Marijuana Use Bad for Teens Brains

Psychology and public health experts claim that that regular cannabis use, which they consider once a week, is not safe and may result in addiction and significant neurocognitive damage to the brains of teenagers and young adults. Washington — Frequent marijuana use can have a significant negative effect on the brains of teenagers and young […]

Reprogramming Your Brain to Work Better

A newly published study demonstrated that weak sequential electromagnetic pulses on mice can shift abnormal neural connections towards their correct locations in the brain. Researchers from The University of Western Australia have shown that electromagnetic stimulation can alter brain organisation which may make your brain work better. In results from a study published today in […]

Researchers Confirm Cellular Basis for Memory by Implanting and Erasing Fear

In a newly published study, scientists at the University of California show the ability to selectively remove a memory and predictably reactivate it by stimulating nerves in the brain at frequencies that are known to weaken and strengthen the connections between nerve cells. Researchers at the University of California, San Diego School of Medicine have […]

New Research Reveals How to Block Stress Damage

By deleting the REDD1 gene in mice, researchers from Yale University were able to block the synaptic and behavioral deficits caused by stress. Ketamine, an anesthetic sometimes abused as a street drug, increases the synaptic connections between brain cells and in low doses acts as a powerful antidepressant, Yale researchers have found. However, stress has […]

Brain Signals Move Paralyzed Limbs

A newly published study details a cortical-spinal prosthesis that directs “targeted movement” in paralyzed limbs. Ithaca, New York – To help people suffering paralysis from injury, stroke or disease, scientists have invented brain-machine interfaces that record electrical signals of neurons in the brain and translate them to movement. Usually, that means the neural signals direct […]

Gene Linking Brain Structure to Intelligence Discovered

An international team of scientists has identified a gene linking brain structure to intelligence, finding that teenagers carrying a particular gene variant had a thinner cortex in the left cerebral hemisphere and performed less well on tests for intellectual ability. For the first time, scientists at King’s College London have identified a gene linking the […]

Researchers Detail How the Architecture of the Brain Shapes Its Functioning

By simultaneously analyzing 1.6 billion connections within the brain, researchers have discovered how the architecture of the brain shapes its functioning. The structure of the human brain is complex, reminiscent of a circuit diagram with countless connections. But what role does this architecture play in the functioning of the brain? To answer this question, researchers […]

Study Shows Caffeine has Positive Effect on Memory

A newly published study from John Hopkins University shows that caffeine has a positive effect of memory, enhancing certain memories at least up to 24 hours after it is consumed. Whether it’s a mug full of fresh-brewed coffee, a cup of hot tea, or a can of soda, consuming caffeine is the energy boost of […]

Human Brain Develops with an Exquisitely Timed Choreography

In a newly published study, researchers analyzed gene expression in human and macaque monkey neocortex, finding that human neocortical development is divided into three major phases. The human brain develops with an exquisitely timed choreography marked by distinct patterns of gene activity at different stages from the womb to adulthood, Yale researchers report in the […]

Oxytocin Improves Brain Function in Children with Autism

A new study from Yale University is the first study to evaluate the impact of oxytocin on brain function in children with autism spectrum disorders, finding that a single spray of oxytocin improves brain function in children with autism. A single dose of the hormone oxytocin, delivered via nasal spray, has been shown to enhance […]
