I love potato chips. There’s something very satisfying about the crunch of a good chip. The problem with chips, other than the obvious effect they have on my waistline, is that I can’t eat just one. Neither can my husband, who loves to open a bag of potato chips while I’m preparing dinner! To explain the disappearance of the potato chips, we joke that the chip-eating culprit in our house is not my husband but a giant mouse that has developed a taste for salty snacks.
If you were around in the 1980s, you remember Nancy Regan telling us to “just say no” to drugs. That campaign focused specifically on the effect crack had on the community. In the 1990s and 2000s, we saw and increase in reports of methamphetamine and heroin overdoses. Though they are perfectly legal, nicotine and even more so, alcohol can be just as damaging on one’s life when used in excess. The War on Drugs launched in the 1970s along with the Just Say No campaign brought tougher sentences related to drug possession, however, this has done little to deter individuals from using drugs. If you have ever had a loved one (friend, family member, or significant other) addicted to drugs or alcohol, you know how devastating it can be to watch their lives spiral out of control. Though society shuns addicts for making such decrepit choices, you wonder, “how could a person possibly choose to live like this?” Continue reading “Your Brain on Drugs: Decision or Disease?”
I love shopping. I mean, I really love shopping. Not the hustle and bustle, mega-mall, door buster debacle but the casual meandering through an antiques store or small, local shop. I buy some things online, but I truly enjoy the process of looking, feeling, and pondering over objects before I purchase them. It has been roughly a year since I set foot in a shopping mall and, just this past week, I had to stop in and pick up a few items that weren’t available online. Now, I know it’s the holiday season and being overwhelmed is 50% of the equation, so I had geared myself up for a crowded, hot, and loud situation.
Forget the wall of people—everyone was relatively cheerful and a simple “Excuse me” or “Pardon me” made navigation a breeze. Hot and stuffy? Not a problem. I left my coat in my car and shivered my way to the entrance. I had just a few things to buy and I can take the heat. The noise level in the mall was roughly a dull roar. There were children being towed (loudly) behind parents with arms full of packages, bell ringers, cell phone talkers, and the like. As a cubicle-dweller and a mother of an exorbitantly talkative five year old, I can tune all that out, too. The problem….the crippling, unforeseen problem Continue reading “Yet another reason to leave the mall….”
I used to work in a physics lab where I was in charge of regularly transferring liquid helium from a tank to a susceptometer (an instrument often used for superconductivity studies). One day, the helium transfer line that I was holding sprung a leak and I froze a good portion of my finger before I was able to stop that leak. Over the days that followed, I could not feel my finger at all and assumed that the nerve damage was permanent. However, as those days turned into weeks and my previously frozen finger healed, I started regaining sensation. After a month had passed, my finger looked and felt just like it had before the helium freeze.
Neurogenesis (the creation of new neurons) is widely accepted as fact for the peripheral nervous system; for example, the nerves in my finger grew back even though I had lost them to frostbite. However, there is the widespread belief that neurons in the central nervous system (CNS) are static and do not multiply after adulthood. The evidence for such belief is everywhere, from spinal cord injuries that result in permanent lifelong paralysis to neurodegenerative conditions such as multiple sclerosis. However, like many widespread beliefs that are simply assumed to be true, nature always finds a way to foil our best laid plans. Continue reading “How Exercise Can Grow Your Brain”
The term ‘phrenology’ conjures up images of nineteenth century medics examining bumps on people’s heads as a means of enciphering key aspects of their character (1). The arch-phrenologist was a man by the name of Franz Josef Gall whose suggestion that “mental faculties might be reflected in the shape of the brain, and hence the skull” kept many a head-feeler on the look out for supportive evidence (1). But soon recognized for the fraud that it was, phrenology lost traction as a discipline worthy of attention by any serious-minded medical practitioner (1).

Without really trying to be, turns out I’m kind of wired for trivia. My brain seems to reserve lots of little nooks and crannies for bits of information that are probably entirely useless to my day-to-day life or career, but man, are they fun to pull out at parties. I can’t tell you why it’s easier for me to remember that horses are largely physiologically incapable of throwing up than it is to recall some of the names of my childhood friends, I just know that’s the way it is. I’ve learned to embrace it. But is trivia useful, or just a waste of gray matter? Turns out, absorption of trivia is a potential tool to engender positive brain plasticity (neuroplasticity), especially as we age and fight the good fight against dementia and memory loss. Continue reading “Neuroplasticity, trivia and a sprinkling of Twitter”
Well, it’s NCAA basketball tournament time and, as this post hits the blog, we’re heading into the second day of “March Madness,” one of my favorite times of the collegiate sports year. Raise your hand if your brackets are already in shambles! Yeah, mine too.*
