You’re running late for work and you can’t find your keys. What’s really annoying is that in your frantic search, you pick up and move them without realising. This may be because the brain systems involved in the task are working at different speeds, with the system responsible for perception unable to keep pace. So says Grayden Solman and his colleagues at the University of Waterloo in Ontario, Canada.
Scientists have now discovered how different brain regions cooperate during short-term memory and in other research -findings that a prion-like protein plays a key role in storing long-term memories
Memories in our brains are maintained by connections between neurons called “synapses”. But how do these synapses stay strong and keep memories alive for decades? Neuroscientists at the Stowers Institute for Medical Research have discovered a major clue from a study in fruit flies: Hardy, self-copying clusters or oligomers of a synapse protein are an essential ingredient for the formation of long-term memory.
Researchers reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.
New research from Uppsala University shows that reduced insulin sensitivity is linked to smaller brain size and deteriorated language skills in seniors. The findings are now published in the scientific journal Diabetes Care.
Age-related delays in neural timing are not inevitable and can be avoided or offset with musical training, according to a new study from Northwestern University. The study is the first to provide biological evidence that lifelong musical experience has an impact on the aging process.
Could brain size determine whether you are good at maintaining friendships? Researchers are suggesting that there is a link between the number of friends you have and the size of the region of the brain – known as the orbital prefrontal cortex – that is found just above the eyes. A new study, published today in the journal Proceedings of the Royal Society B, shows that this brain region is bigger in people who have a larger number of friendships.
Scientists have long believed that human speech is processed towards the back of the brain’s cerebral cortex, behind auditory cortex where all sounds are received – a place famously known as Wernicke’s area after the German neurologist who proposed this site in the late 1800s based on his study of brain injuries and strokes. But, now, research that analyzed more than 100 imaging studies concludes that Wernicke’s area is in the wrong location. The site newly identified is about 3 centimeters closer to the front of the brain and on the other side of auditory cortex – miles away in terms of brain architecture and function.
New research from Cold Spring Harbor Laboratory (CSHL) might help explain how a gene mutation found in some autistic individuals leads to difficulties in processing auditory cues and paying spatial attention to sound.
Neuroscientists may one day be able to hear the imagined speech of a patient unable to speak due to stroke or paralysis, according to University of California, Berkeley, researchers.
Cocaine-dependent men and women might benefit from different treatment options, according to a study conducted by Yale School of Medicine researchers.
New research finds problems that require a flash of illumination to solve are best approached during the time of day when you’re not at your peak.
Researchers for the first time are documenting the basic wiring of the brain, the complex relationships among billions of neurons that are responsible for reason, memory and emotion. The work eventually could lead to better understanding of schizophrenia, autism, multiple sclerosis and other disorders.
