Brain Blogger covers topics from multidimensional biopsychosocial perspectives. It reviews the latest news and stories related to neuroscience, psychiatry, and neurology. It serves as a focal point for attracting new minds beyond the science of the mind-and-brain and into the biopsychosocial model.
I have yet to form a solid opinion regarding universal health coverage. Regardless of what I conclude to be the best policy, I am glad that the issue is out there. But I wish that this topic was more extensive; I wish that our country would broaden its’ definition of healthcare to include alternative treatments.

Women take a lot of criticism for premenstrual syndrome, being accused by male friends and partners of irritability and moodiness. Now, women may have a good explanation for their behavior.
During the 2 weeks before their period, women experience a gradual surge of progesterone secretion. Progesterone is produced by an ovulated egg within the ovaries, and ... Read more »

Law enforcers now have all the proof they need for tougher anti-cell phone measures for drivers, as the latest published neurological study shows that there is a 37% reduction in parietal cortex activity with driving. Arguments that there are many among us who can multi-task well have taken a back seat in recent studies involving ... Read more »

We’ve examined the common reasons people stop taking anti-depressants. That’s part of this puzzle. We’ve looked at the difficulty of proving the type of depression an individual has. Now, let’s answer the big question: why does the “cause” of depression really matter? Let’s start with something that happened recently.

Functional MRI (fMRI) is one of the most widely used experimental tools in neuroscience today, which allows us to study blood flow patterns to different parts of the brain during a given task. For example during solving mathematical problems, a typical fMRI pattern is seen. Recently however, psychological theories are being tested, and a broader ... Read more »

A few weeks ago, I wrote about irritable bowel syndrome (IBS) and the abnormal brain activity seen on magnetic resonance imaging (MRI) in a recent clinical trial. These findings supported the theory that patients with IBS have an altered sensation of abdominal pain and respond more strongly and more emotionally to pain than unaffected patients.

The benefits of spending time outdoors are numerous –- fresh air, sunshine, relaxation. Who wouldn’t want that? Apparently, many Americans don’t. Researchers at the University of Illinois in Chicago tracked outdoor activities over several decades, and found a sharp decline among US citizens. Rates of fishing, hiking, hunting, backpacking and national and state park visits ... Read more »

The American Academy of Pediatrics issued a press release calling for ABC to cancel its pilot episode of a new drama Eli Stone. Renee R. Jenkins, MD, President of the AAP, accused ABC of “reckless irresponsibility” in screening a television program that may give parents the false impression that vaccines cause autism. She goes on ...

Magnetoencephalography (MEG) is an imaging technique that is currently being used before resective surgery in pediatric epilepsy patients to determine whether or not surgery is necessary and if the surgery will be successful. Before this technique was implemented, doctors had to rely on symptoms caused by seizures and traditional techniques that did not provide sufficient ... Read more »

New research findings from the Stanford University proves that men find playing video games more rewarding. This wouldn’t appear surprising to the millions of console and PC gaming widows worldwide, but this gives us an opportunity to have a look at the good old chicken-and-egg conundrum in the context of arriving at sweeping generalizations on ...

Mammograms are recommended for all women over the age of 45 as a breast cancer screening tool. Some insurance and Medicare plans provide full coverage for these tests because they are deemed necessary and beneficial. Other plans apply co-pays to mammograms, and other similar medical interventions, despite the prevalent medical opinion that they are both ... Read more »

While a number of studies have shown that negative social behaviors and emotional states tend to correlate with a lower overall level of physical health, few have sought to illuminate a link between emotional vitality and physical well-being. A recent study provides evidence that there may, indeed, be a connection. Six thousand twenty-five men and ... Read more »

I never quite got around to write the sequel to Barbara and Allan Pease’s evocative work (1), although I had figured out a nice name for it, “Why men don’t use makeup, and women can’t Sumo wrestle.” Not to make fun of the genetic determinists who study gender differences, but to drive home the whole ...

A new study from the Northwestern University’s Feinberg School of Medicine has provided important clues to how chronic pain might throw our lives out of gear by affecting many areas of the cerebral cortex. Worse, if left unchecked, it could lead to irreversible damage to the interconnection between the neurons, leading to permanent changes in ... Read more »
