Improving memory is a quest that never seems to end. For centuries, humans have attempted to find the right combination of social actions to better retain what we’ve learned. Over the years, some options have shown promise such as fasting and strenuous exercise. While effective, they are not particularly popular. Then there’s the odd concept of intranasal injection of insulin. It goes to show that an idea with promise might not be the best idea.
Acquiring a language is a difficult process. One of the best ways to learn involves the use of a tutor. This one-on-one interaction allows for direct learning as well as interaction without distraction. Usually, the teacher is an expert in that specific language. But when it comes to learning a first language, the most useful tutor happens to be an infant’s parent.
Most people take motion sensing for granted. Our eyes pick up on something moving and our brains are sent a signal to let us know something has occurred in our space-time continuum. Despite the simplicity of the task, the mechanisms allowing us this ability are incredibly complex. They have been studied for over fifty years and the neural circuitry underlying motion detection is probably the best described circuitry in the brain. Yet, researchers have not discovered all the answers.
As the most common and aggressive cancerous brain tumour in adults, a glioblastoma diagnosis remains a death sentence due to its resistance to all currently-available treatments. Research in this area has been slow and steady to date. Now, with promising new findings, a Canadian team of scientists is ushering brain cancer research into a new realm: the field of neurodegenerative medicine and neurochemical signalling.
Some memories just seem to go together. Think about an important experience in your life. You may also closely remember another experience that happened around that time too, like exchanging vows at your wedding, and then your friend’s epic dance moves later that same night. Somehow these two memories seem to be linked in your mind.
A new study led by The Hospital for Sick Children (SickKids), looks at this connection between memories and illustrates how certain memories become linked in the brain. The study is published in the July 22 online edition of Science.
Dan Randles: “We don’t fully understand how acetaminophen affects the brain”
It’s been known for more than a century that acetaminophen is an effective painkiller, but a new University of Toronto study shows it could also be impeding error-detection in the brain.
For years, neuroscientists have puzzled over how two abnormal proteins, called amyloid and tau, accumulate in the brain and damage it to cause Alzheimer’s disease (AD). Which one is the driving force behind dementia? The answer: both of them, according to a new study by researchers at the Douglas Mental Health University Institute.
In the journal Molecular Psychiatry, the team led by Dr. Pedro Rosa-Neto, a clinician scientist at the Douglas and assistant professor of Neurology, Neurosurgery and Psychiatry at McGill University, reports for the first time evidence that the interaction between amyloid and tau proteins drives brain damage in cognitively intact individuals.
A new study from Western University shows that the parts of our brain that provide us with our sense of touch are activated when we watch someone else learn a manual skill.
The findings by Heather McGregor and Paul Gribble from Western’s Brain and Mind Institute were published by the prestigious journal Current Biology.
