A study published last month in the journal of Nature Neuroscience used MR imaging to research the changes in the brain brought about by pregnancy. The study, entitled ‘Pregnancy leads to long-lasting changes in human brain structure’, discovered a reduction of gray matter regions pertaining to social cognition in the brains of pregnant women. The research was […]

Does brain size matter? MRI Study

It’s never a compliment to be called a “birdbrain” or a “peabrain.” But does brain size even matter? According to researchers from the University of Southern California, it might. In a new study published Monday in Nature Neuroscience, scientists scanned 32, 438 adults in one of the biggest studies to date in the ongoing research […]

Researchers induce feelings about faces: MRI Study

A new MRI study has located the cingulate cortex as the brain region responsible for forming positive or negative associations with people’s faces. The researchers also experimented with manipulating the emotional responses of their subjects, ie. inducing them to feel a certain way about certain faces. “Face recognition is a very important social function for […]

MRI-guided ultrasound a non-surgical option for essential tremor

Essential tremor, a neurological disorder that affects millions of people, is not a terminal condition but is one that greatly impedes upon quality of life. Characterized by continuous and rhythmic shaking, most often occurring in the hands or voice, sufferers of essential tremor are unable to perform routine tasks such as tying shoelaces or picking […]

Brains of obese look 10 years older at middle age: MRI Study

Packing on the pounds may increase your body mass index, but it won’t increase brain volume, according to a new MRI study. Although the human brain inevitably shrinks as it ages, researchers have found that the brains of obese subjects appear 10 years older at middle age than their fitter counterparts. The UK study, entitled […]

Similarities in brains of children with autism, OCD and ADHD: MRI study

A Canadian MRI study has found similarities in the brain scans of children with autism, Obsessive Compulsive Disorder (OCD) and ADHD.

The schizophrenic brain attempts to repair itself: MRI study

Few diseases are stigmatized as much as schizophrenia, or other similar mental health illnesses. But things are looking up: according to new MRI research, brains afflicted with schizophrenia show an ability to identify and fight off the disease. The study, entitled Dynamic cerebral reorganization in the pathophysiology of schizophrenia: a MRI-derived cortical thickness study, was […]

MRI study explores effects of mom’s voice on child’s brain

While it comes as no surprise that MRI scans reveal powerful activity in infants’ brains upon hearing the voices of their mothers, scientists were looking for more specific information. “Many of our social, language and emotional processes are learned by listening to our mom’s voice,” said study author Daniel Abrams. “But surprisingly little is known about how the […]

Words stored in specific brain regions: MRI Study

Another brain fMRI study, another step closer to mind reading! Researchers from Berkeley have mapped out a “semantic atlas”–that is, an interactive map of which words activate what areas of the brain. The study, Natural speech reveals the semantic maps that tile human cerebral cortex, has just been published in Nature. Check out the video below to learn […]

First ever look at the brain on LSD: MRI study

In the 1950s and 60s, researchers at the forefront of neuroscience and psychology experimented with LSD for PTSD and depression. Despite the positive effects of treatments (which came in small doses in controlled environments) the drug and corresponding research on its therapeutic benefits were banned in North America in the late sixties. Newly published research which used MRI for […]

Diffusion MRI study looks into insomnia

Although it can’t claim to have found out what causes those sleepless nights, a new MRI study has shed some light on the mysterious common sleeping disorder known as insomnia. For the study, published recently in the Radiology  journal, researchers based in Guangzhou, China, scanned the brains of 23 clinical insomniacs (patients whose restless sleeping habits […]

Take the stairs for better brain health: MRI study

To ride the elevator or climb the stairs may not seem like an important decision, but when it’s a decision you make every day it could have lasting implications on not only your physical fitness, but your cognitive function as well. A new Canadian MRI study from researchers at Concordia University has found that younger-looking […]

Over the next several months AIM will be providing imaging for a major cross-country MRI research study that seeks to illustrate patterns in heart and brain health of Canadians from coast to coast. The Canadian Alliance for Healthy Hearts and Minds, or CAHHM, will study the MRI results of approximately 9700 participants of varying ages, backgrounds […]

Couch potatoes risk brain as well as muscle atrophy: MRI study

To exercise your mind you have to exercise your body, say the results of a newly released MRI study that was 20 years in the making. The study, published February 10 in the journal of Neurology, has its roots in the 1990s when 1,583 middle-aged (average age 40 years) participants took a treadmill test and a […]

Psychiatrists urge caution of overreliance on fMRI brain studies

Two leading mental health professionals have cast doubt on the increasingly common practice of using fMRI studies to pinpoint the sites of psychiatric illnesses on anatomical images of the brain. In their report, Finding the Elusive Psychiatric “Lesion” with 21st-Century Neuroanatomy: A Note of Caution, published in the American Journal of Psychiatry, authors Dr. Eugenia Radulescu […]

What the Holidays do to Your Brain: MRI Study

The hashtags #backtowork and the less subtle #backtoworkblues appeared across Twitter on Monday as millions of people bade the holiday season farewell and settled back into their routines. While it’s natural to begrudge getting up early after an extended break of sleep-ins and visits with loved ones, is there something about the holiday season that […]

No Distinct Differences Between Male and Female Brains: MRI Study

Could differences in male-female behaviours simply be social conditioning? One thing’s for sure, they’re not anatomical; a new MRI study has found no distinct differences between male and female brains. The study, entitled Sex beyond the genitalia: The human brain mosaic was published Monday in Proceedings of the National Academy of Sciences. The researchers, based at Tel-Aviv University, scanned over […]

What Causes Happiness? MRI Study

Self-help literature abounds with the quest for happiness: what causes it and how can you get some of your own? But what does neuroscience have to say on the subject? A new MRI study from Korean researchers offers new information to the happiness market. The study, entitled The structural neural substrate of subjective happiness, was […]

MRI Study Reveals What Makes Humans More Intelligent than Chimps

Chimpanzees, famous for their abilities to learn sign language and use tools, have long been a source of fascination for humans. While chimps are one of the smartest animals on the planet and show remarkable capacity for learning new skills, their cognitive achievements are relatively small when compared with the human brain. New research has […]

What is Disturbing About Screams? MRI Study

What is so disturbing about screams? Aside from the obvious–that they represent a fellow human’s pain or fear of mortal peril? While it may seem clear on an emotional level why a scream is an upsetting sound to hear, scientifically, it appears that screams and other rapid changes in volume trigger the fear centres within […]

The MIND Diet for Prevention of Alzheimer’s

Dementia is on the rise, but fortunately so are solutions for preventing it. A new MRI study has linked smaller size of certain brain structures–such as hippocampi–to an increased risk for dementia. People who are aware that they may be at higher risk may then make greater efforts to fight it–strengthening the brain through cerebral exercises and […]

What Lucid Dreaming Ability Reveals About You: MRI Study

Did you know there are conferences for lucid dreamers? Or dedicated post-secondary researchers on the subject, such as the folks at the Stanford Sleep Lab? People are curious about the phenomenon–the ability to come to conscious awareness in the dreaming state. Perhaps they would like to learn how to swallow fire or visit the sun, […]

Are brains of high-achievers wired differently?

In 2008, Canadian author Malcolm Gladwell attempted to dissect the methodology behind high achievement in his book Outliers: The Story of Success. Interestingly, he credited an individual’s cultural legacy and societal influences as primary precursors when he wrote: “It is those who are successful, in other words, who are most likely to be given the kinds of special […]

Failure Activates Reward-Based Learning: MRI Study

“I have not failed. I’ve just found 10,000 ways that won’t work,” said Thomas Edison. He was certainly successful in making that statement; a new MRI study has found that when the brain is able to learn from its mistakes, failure is actually a rewarding experience. The study, by researchers from the University of Southern […]

Sleeping Position Affects Brain Health: MRI Study

How do you sleep? Most people have a fairly consistent sleeping location, schedule and position. And, according to new MRI research, the position you favour may have something to do with long-term brain health.
