Your Brain or Your Personality?

Brain StructuresWhat makes you act the way you do?

A new study conducted by Colin G. DeYoung and colleagues from the University of Minnesota suggests that certain personality traits are related to certain brain structure sizes.

The study finds that extraverts have an enlarged orbitofrontal cortex, which is the part of the brain that registers rewards. These individuals are cheerful, assertive, and competitive.

However, the study could not find cause-and-effect, meaning scientists are still unsure whether the brain structure causes the personality trait or the trait causes the changes in brain structure, as personalities are (for the most part) constant, but do possess the ability to change over time.

The study used an MRI scan of over 100 people after each individual’s personality type had been determined by the Big Five: extraversion, agreeableness, conscientiousness, neuroticism, and openness/intellect.

Those identified as conscientious (hard working and self-disciplined) also had a large lateral prefrontal cortex.

Those identified as neurotic (negative and depressed) had a smaller medial prefrontal cortex, which regulates emotion.

Those identified as open (creative) actually had no drastic changes in brain structures.

The article on the study can be found here. If you want to see where your personality stands, schedule an MRI with Rosetta Radiology by calling 212-744-5538 or visit our website for more information.

A Healthy Complexion is a Healthy You



As temperatures rise, so does the risk of sunburn. We don’t want you to avoid a central park picnic, but we do want you to be as safe as possible.

Zoe Ruderman with Cosmopolitan wrote an article (which can be found here) about the 2011 regulations for practicing safe sun.

The first thing to understand is what you need protection from: sun rays in general. If a sunscreen protects against UVB rays, UVA may still be damaging your skin, especially those with SPF values under 15. The cancerous rays are still a serious hazard.

Next, “waterproof” really probably means “water resistant,” so be careful at the beach or pool. Make sure your face and shoulders are well covered to protect against reflected rays, and reapply when you get out.

Because of these common misconceptions, the FDA requires anything with under SPF 15 will come with a warning, and waterproof/sweatproof cannot be printed on the packaging.

If a package advertises as “broad spectrum,” now you know that they’ve been tested for UVA and UVB rays and work.

Want a more hi-tech way to stay safe? Cosmo highlights five apps that help check your skin for damage that needs attention.  They are:



  1. Copptertone My UV Alert: check UV levels in your area, alter you when it’s time to reapply
  2. UMSkinCheck: watch for changing/growing moles and freckles
  3. Have You Checked Your Skin Lately?: a risk calculator tailored to your lifestyle, a how-to for skin checks
  4. MelApp: send in pictures of moles to be checked by the Johns Hopkins University Medical Center, get a list of specialists in your area
  5. Sun Safe: uses location and skin type to customize what SPF you should be using at that time/place

We expect more to pop up over time as these become more popular. Rosetta Radiology wants you to stay as safe as possible!

Migraines: The How and Why?



Are you one of the 300 million people that suffer from intense, throbbing headaches? Do they make you nauseated, sick, or sensitive to light? Migraines are not something that can be cured with an ibuprofen or a few deep breaths.

To learn what a migraine is, from a lovely British point of view, watch the short video below.

Dr. Filippi and colleagues believe that migraines occur because of problems with the brain that develop over time. They used MRIs to measure the cortical regions (outer regions) of the brain, and most with migraines show atrophy related to pain processing. This is most likely due to chronic stimulation of the area.

The MRIs checked for thickness and surface abnormalities. They found that individuals with intrinsic predisposition can alter the surface area, and disease-related processes, or over-stimulation, could lead to changes in thickness.

The study is still ongoing, checking back with patients longitudinally. To read more on it, you can view the article here.

To see if you are at risk for migraines, or to cure the headaches you currently have, call Rosetta Radiology at 212-744-5538 or visit our website for more information.

Diet for Dreams

SleepFood for thought is overrated. We want you experience some of the healthiest ways to ease your body into a healthy sleep.

You know that delicious drowsiness that follows a Thanksgiving turkey or a large bowl of pasta? Well the writers at Yahoo! Health found six healthy options to relax your mind and body.

1 – Bananas. The amount of sugar in a banana is the perfect amount to calm your orexin cells without keeping you wired and awake. Your muscles relax as they respond to the potassium and magnesium.

Passionfruit Tea2 – Passionfruit Tea.  A study in Australia found that, while compared to parsley tea, the participants slept more soundly with passionfruit tea. They believe the nervous system is responding to the harman alkaloids.

3 – Hummus. Similar to that Thanksgiving turkey, hummus actually has almost double the amount of L-tryptophan, the amino acid that makes you sleepy. Not a fan of hummus? Or even turkey? The article also suggests elk and sesame seeds.

4 – Dates. Combining the aforementioned L-tryptophan with carbs will make it work better. Luckily, dates have both carbs and the amino acid. Not a fan? Try fruit or air-popped popcorn.

Chinese Food

5 – Chinese Food. GABA (gamma-aminobutyric acid) is theneurotransmitter that calms your brain down. While foods aren’t “rich” in neurotransmitters, Chinese food naturally calms your brain because it’s high in glutamic acid which affects the GABA levels.

Cherries6 – Cherries. The European Journal of Nutrition found that one ounce of cherry juice twice a day can help people sleep an extra 25 minutes a night. Why? Like hummus, cherries are full of L-tryptophan which produces melatonin.

To read more about these sleepy tricks, and see these pictures, read the article here.

MRIs Helping Alter Sports Regulations

We all watch sports and think it’s cool when something bad happens. Viewers wait for a Nascar crash and an NFL sack, but these things, even things as simple as soccer heading, can cause damage to our favorite athletes. In fact, “At least 1.6 million sports- and recreation-related traumatic brain injuries occur in the United States annually.”

Dr. Michael Lipton and others at the Albert Einstein College of Medicine of Yeshiva University studied just how much heading is too much. They used their $3 million grant (awarded by the National Institute of Health) to find long and short term consequences.

They found that heading the ball at least 1,000 times in a year was more likely to lead to cognitive impairment and mild traumatic brain injury than players who headed less.

This serves as the basis for further research. The new study will gather 400 soccer players, male and female, and use an advanced MRI tactic to follow the participants over two years. This tactic is called diffusion tensor imaging, and some may recognize it from our previous article about helping our veterans (found here).

By completing this study, the safety guidelines for these sports can be altered to better protect its players. To read more on the topic, you can view the article here.

A Big Step in Understanding Parkinson’s



The Massachusetts Institute of Technology and Massachusetts General Hospital paired up to research just what happens to the brain during Parkinson’s disease. What they found could lead to better treatment and further research.

Tremors, stiffness, and weakness are known as the symptoms of Parkinson’s disease, and there’s no denying how awful this experience can be. However, research never allowed us to see into the brain to understand why these things happened. We just knew that they did.

The researches took four MRI scans, all on the same machine but with different settings, to create one combined image. This image could dive deep into the brain to see what a regular scan could not.

They found that the substantia nigra, associated with movement, was targeted first, followed by the basal forebrain, associated with memory and attention. The disease actually kills brain cells, so these structures actually shrink as the Parkinson’s progresses.

Because the severity of the known symptoms vary so much from patient to patient, these scans can help doctors see what is happening to individuals living with this disease and treat them accordingly. Do they need more dopamine or maybe acetylcholine or is their dementia going to be the biggest problem? These questions can be answered.

Once we know more about treating the symptoms, we’re one step closer to treating the cause of the disease. For more information on this research, click here.
