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.
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.
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.
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.
Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new research.
A new study focused on mental well-being found that high and low mental well-being were consistently associated with an individual’s fruit and vegetable consumption.
Individual differences in early language development, and in later language functioning, are associated with changes in the anatomy of the brain in autism. A new study has found that a common characteristic of autism– language delay in early childhood– leaves a "signature" in the brain.
A new study reports preliminary results showing that a blood test, when used in psychiatric patients experiencing symptoms that are considered to be indicators of a high risk for psychosis, identifies those who later went on to develop psychosis.
Researchers found that participants with a western dietary pattern scored lower in cognitive tasks, particularly those involving reaction time/psychomotor function, visual attention, learning and memory.
For years, neuroscientists have been trying to develop tools that would allow them to clearly view the brain's circuitry in action— from the first moment a neuron fires to the resulting behavior in a whole organism.
While previous studies of the brain suggest that processing of objects and place occur in very different locations, a research team has found that they are closely related.
On this episode of Bioscience Technology This Week, Christina Jakubowski focuses on a new study that used a short movie to detect consciousness in vegetative state patients. Our second story explores how the amazing variety in human faces is the result of evolutionary pressure.
Researchers say a new focus on the links between the immune system and stress is needed to help pave the way for improved treatments of severe depression. The paper argues that current treatments for major depressive disorder lack effectiveness.
Spontaneous mutations in the brain gene TBR1 disrupt the function of the encoded protein in children with severe autism. In addition, there is a direct link between TBR1 and FOXP2, a well-known language-related protein, according to a new study.
Scientists have found that confidence is actually a measureable quantity, and not reserved just for humans. The team has identified a brain region in rats whose function is required for the animals to express confidence in their decisions.
Stanford scientists have shown how the brain changes throughout life, and created a standard curve that can be used to assess whether patients are maturing and aging normally.
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
A peek inside the brains of more than 750 children and teens reveals a key difference in brain architecture between those with attention deficit hyperactivity disorder and those without.
Researchers have used brain scans to predict how young children learn to read, giving clinicians a possible tool to spot children with dyslexia and other reading difficulties before they experience reading challenges.
A new study shows how schizophrenia is associated with increased rates and intensity of tobacco smoking by showing that the level of nicotine receptors in the brain was lower in schizophrenia patients than in a matched healthy group.
Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans’ unique ability to produce and understand speech.
A rare genetic disorder known as Jacobsen syndrome has been linked with autism, according to a recent joint investigation by researchers. In addition to suggesting better treatment options for people with Jacobsen syndrome, the finding also offers more clues into the genetic underpinnings of autism.
The human brain is capable of a neural workaround that compensates for the buildup of beta-amyloid, a destructive protein associated with Alzheimer’s disease, according to a new study.
