Study finds that six brain regions shared more responsibility than thought for how the brain moves from raw perception to determining the categorical meaning of what's seen.
A new Tel Aviv University study suggests that noradrenaline, a neurotransmitter responsible for arousal in the brain, plays a vital role in early sensory perceptions of the world.
Researchers used brain imaging to gauge how the hand, foot and lips are represented in the brains of 2-month-olds -- a much younger age than has been studied previously. It is believed to be the first to reveal the greater neurological activity associated with the lips than with other body parts represented in the infant brain. It also indicates how soon infants' brains begin to make sense of their bodies, a first step toward other developmental milestones.
A new study shows that updating visual perceptual skills -- which humans rely on to recognize what they see, including potential threats, and ignore unimportant background -- is an active process with many similarities to the way they stabilize memories.
Changing public health messaging to focus on the impact of our actions -- for example the potentially harmful impact of infecting a colleague with a cold, rather than whether we will infect them if we go into work in the first place -- could have significant implications for how we deal with global threats, according to a new study from City University of London, the Oxford Martin School (University of Oxford), and Yale University.
Finnish researchers have gained new information on brain activity during general anesthesia by recording changes in the electrical activity of the brain. They discovered that changes in electroencephalogram correlated with the loss of consciousness itself and also by the non-specific effects of the drugs. Nearly all participants recalled dreaming during unresponsiveness and, somewhat surprisingly, words presented during anesthesia were still processed in the brain even though the participants were unable to recall them later.
The posterior parietal cortex plays a crucial role in allowing the mammalian brain to turn visual information (such as a green traffic light), into motion (such as stepping on the gas), researchers at MIT's Picower Institute found in a new study.
Research has found that contact with healthcare professionals, support from peers and access to regular organized exercise sessions help people with chronic lung conditions to be physically active.
Research from the University of Pennsylvania shows that using minimally invasive electrical currents on the brain's prefrontal cortex can reduce the intention to carry out physical and sexual assault. It's a new and promising approach to interventions around violence.
As demonstrated in a series of new studies, Harvard researchers show that as the prevalence of a problem is reduced, humans are naturally inclined to redefine the problem itself. The result is that as a problem becomes smaller, people's conceptualizations of that problem become larger, which can lead them to miss the fact that they've solved it.
