The possible risks to your brain of multi-tasking

by Dr. Travis Bradberry You may have heard that multitasking is bad for you, but new studies show that it kills your performance and may even damage your brain. Every time you multitask you aren’t just harming your performance in the moment; you may very well be damaging an area of your brain that’s criticalContinue reading “The possible risks to your brain of multi-tasking”

Small RNA identified that offers clues for quieting the “voices” of schizophrenia

St. Jude Children’s Research Hospital scientists have linked disruption of a brain circuit associated with schizophrenia to an age-related decline in levels of a single microRNA in one brain region St. Jude Children’s Research Hospital scientists have identified a small RNA (microRNA) that may be essential to restoring normal function in a brain circuit associatedContinue reading “Small RNA identified that offers clues for quieting the “voices” of schizophrenia”

‘Brain wi-fi’ shown to be able to reverse leg paralysis in a primate.

By James Gallagher An implant that beams instructions out of the brain has been used to restore movement in paralysed primates for the first time, say scientists. Rhesus monkeys were paralysed in one leg due to a damaged spinal cord. The team at the Swiss Federal Institute of Technology bypassed the injury by sending theContinue reading “‘Brain wi-fi’ shown to be able to reverse leg paralysis in a primate.”

US military enhancing human skills with electrical brain stimulation

Study paves way for personnel such as drone operators to have electrical pulses sent into their brains to improve effectiveness in high pressure situations. US military scientists have used electrical brain stimulators to enhance mental skills of staff, in research that aims to boost the performance of air crews, drone operators and others in theContinue reading “US military enhancing human skills with electrical brain stimulation”

Pain Sensitivity Can Be Socially Transmitted Via Olfactory Cues

by Tori Rodriguez, MA, LPC The social transmission of emotions has been reported in several studies in recent years. Research published in 2013, for example, found that joy and fear are transmissible between people, while a 2011 study showed that stress — as measured by an increase in cortisol — can be transmitted from othersContinue reading “Pain Sensitivity Can Be Socially Transmitted Via Olfactory Cues”

Birds with bigger brains appear to be better able to avoid getting shot

by Jaymi Heimbuch When a flock of geese fly into the air and a hunter takes aim, which bird is most likely to drop from the sky? A new study published in the journal Biology Letters shows that those birds with larger brains relative to their body size are less likely to be shot byContinue reading “Birds with bigger brains appear to be better able to avoid getting shot”

Potential target identified for preventing long-term effects of explosion-mediated traumatic brain injury

BY: JENNIFER BROWN More than 200,000 U.S. soldiers serving in the Middle East have experienced a blast-related traumatic brain injury, making it a common health problem and concern for that population. Traumatic brain injury (TBI) can have various harmful long-term neurological effects, including problems with vision, coordination, memory, mood, and thinking. According to the CentersContinue reading “Potential target identified for preventing long-term effects of explosion-mediated traumatic brain injury”

Boy wakes up from coma speaking an entirely different language

By Cari Romm You may have heard of foreign-accent syndrome, a rare and mysterious condition in which someone suffers a brain injury and suddenly — true to the name — begins speaking in a new accent. Last year, for example, a woman from Ontario began speaking in the regional accent of the Canadian East CoastContinue reading “Boy wakes up from coma speaking an entirely different language”

Zika may hurt the adult brain.

By Meghan Rosen Zika may harm grown-up brains. The virus, which can cause brain damage in infants infected in the womb, kills stem cells and stunts their numbers in the brains of adult mice, researchers report August 18 in Cell Stem Cell. Though scientists have considered Zika primarily a threat to unborn babies, the newContinue reading “Zika may hurt the adult brain.”

A metabolic shift in neurons may provide insight into neurodegenerative diseases

A key metabolic pathway must be switched off during neuron development or fewer neurons (green, on the right) survive. by Jennifer Hicks Researchers at the Salk Institute of Biological Studies released a study in the July 12 issue of eLife, which identifies the point at which there’s a dramatic metabolic shift in developing neurons. ThisContinue reading “A metabolic shift in neurons may provide insight into neurodegenerative diseases”
