Even before he lost his right hand to an industrial accident four years ago, Igor Spetic had family open his medicine bottles. Cotton balls give him goose bumps. Now, blindfolded during an experiment, he feels his arm hairs raise when a researcher brushes the back of his prosthetic hand with a cotton ball.
Autism is characterized by many different symptoms: difficulty interacting with others, repetitive behaviors, and hypersensitivity to sound and other stimuli. Neuroscientists have put forth a new hypothesis that accounts for these behaviors and may provide a neurological foundation for many of the disparate features of the disorder.
When kids say “the darnedest things,” it’s often in response to something they heard or saw. Now researchers found that children as young as 15 months can detect anger when watching other people’s social interactions and then use that emotional information to guide their own behavior.
A U.S.-British scientist and a Norwegian husband-and-wife research team won the Nobel Prize in medicine Monday for discovering the brain's navigation system - the inner GPS that helps us find our way in the world - a revelation that could lead to advances in diagnosing Alzheimer's.
A “mini-stroke” may increase your risk of developing post-traumatic stress disorder (PTSD), according to new research. The study found that one in three transient ischemic attack (TIA) patients develop PTSD.
Curiosity helps us learn about a topic, and being in a curious state also helps the brain memorize unrelated information, according to new research. The study provides insight into how piquing our curiosity changes our brains.
Scientists studying two genes that are mutated in an early-onset form of Parkinson’s disease have deciphered how normal versions of these genes collaborate to help rid cells of damaged mitochondria.
People make immediate judgments about images they are shown, which could impact on their decisions, even before their brains have had time to consciously process the information, a study of brainwaves has found.
Schizophrenia and bipolar disorder both appear to be associated with dendritic spine loss in the brain, according to a new study, which suggests that the two distinct disorders may share common pathophysiological features.
Ongoing research is investigating the connection between initial seizures and the onset of epilepsy later in life. Nearly one in 10 Americans will experience an initial seizure, but only 3 percent of those who experience a seizure will go on to develop epilepsy.
Omega-3 fatty acids, more commonly known as fish oil, have a long list of health benefits, including lowering the risk of heart disease and reducing triglyceride levels. These nutritional compounds are also known to have anti-depressant and anti-inflammatory properties.
In the first small study of a novel, personalized and comprehensive program to reverse memory loss, nine of 10 participants displayed subjective or objective improvement in their memories.
Here’s another reason why it’s a good idea to hit the gym: it can improve memory. A new study shows that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults.
Scientists have moved a step closer to improving medical science through research involving muscle manipulation of fruit flies. They discovered in the flight muscles of Drosophila a new regulator of a process called alternative splicing.
Researchers have developed a scaling law that predicts a human’s risk of brain injury, based on previous studies of blasts’ effects on animal brains. The method may help the military develop more protective helmets, as well as aid clinicians in diagnosing traumatic brain injury.
The National Institutes of Health announced today its first wave of investments totaling $46 million in fiscal year 14 funds to support the goals of the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative.
On this episode of Bioscience Technology This Week, Christina Jakubowski covers mosquitoes infected with a dengue-blocking bacteria that have been released in Brazil. Our second story highlights new research that has restored natural walking ability in completely paralyzed rats.
How the brain ages is still largely an open question– in part because this organ is mostly insulated from direct contact with other systems in the body, including the blood and immune systems. Now, new research may have found evidence of a unique “signature” that may be the “missing link” between cognitive decline and aging.
Researchers have shown that low levels of the protein progranulin in the brain can increase the formation of amyloid-beta plaques (a hallmark of Alzheimer’s disease), cause neuroinflammation, and worsen memory deficits in a mouse model of this condition.
A new study further supports an inescapable message: caregivers have a profound influence— good or bad— on the emotional state of individuals with Alzheimer’s disease.
Tests on the brains of macaques have shown that neurons in at least two regions of the brain, the temporal and frontal lobes, are responsible for deciding which impressions reach our consciousness.
New research suggests that people who notice their memory is slipping may be on to something. The research appears to confirm that self-reported memory complaints are strong predictors of clinical memory impairment later in life.
The first animal model for ALS dementia, a form of ALS that also damages the brain, has been developed by scientists. The advance will allow researchers to directly see the brains of living mice, under anesthesia, at the microscopic level.
On this episode of Bioscience Technology This Week, Christina Jakubowski covers research showing that measuring the brain’s response to sights and sounds can help in classifying people on the autism spectrum. Our second story looks at how the human response to unfairness may have involved in support of long-term cooperation.
Infants’ vocalizations throughout the first year follow a set of predictable steps from crying and cooing to forming syllables and first words. New research shows that infant vocalizations are primarily motivated by infants’ ability to hear their own babbling.
