How much could brain stimulation help you?

Online, you can buy the headset below for $250. It promises to "overclock your brain" by "pass[ing] a small electric current (<2.05mA) through the prefrontal cortex of the wearer[,] making their synapses fire faster."

Other headsets sell for less than $60. They use transcranial direct current stimulation, or tDCS. It works by running a very low-voltage electrical current through your brain, strengthening its connections.

tDCS is "broadly considered safe for routine application even in healthy subjects." Withholding it from patients is often considered more dangerous than using it to help them. After over 50 thousand sessions of tDCS in clinical studies, no serious side effects have been reported.

The prefrontal cortex (PFC) is on the surface of the brain directly behind the forehead, making it one of the easiest brain areas to stimulate. As I described in part one of this series, increasing PFC neural activity can increase self-control and cognitive empathy. If tDCS devices can enhance the PFC and increase those capabilities, then they are a relatively cheap and easy tool for self-improvement.

A young but growing body of research has found that tDCS can reduce impulsivity and cravings for nicotine, alcohol and methamphetamines. It can increase caution, complex thought and performance on cognitive tasks including multitasking, and it may also be beneficial for learning.

In addition to enhancing working memory and self-control, it also might be an effective treatment for depression. It may even improve social skills. While the current method sometimes only provides temporary benefits, an advancement called transcranial Random Noise Stimulation provided a long-lasting benefit in learning math.

All of these benefits explain the rising popularity of tDCS devices. Even the U.S. military is using tDCS to help train drone pilots, for example, but the popularity of tDCS extends beyond official use. Many tDCS enthusiasts have purchased devices for personal use, and some have actually taken to constructing their own tDCS devices.

Before you rush out and buy a tDCS headset online, though (or make one yourself) it may help to know that researchers have sent out "a plea for extreme caution" about use by consumers.

The FDA is still figuring out regulations on the technology, since it could have negative effects if misused. For example, tDCS electrodes must be placed extremely precisely on the head; if placed incorrectly, they could alter the wrong brain regions. They must also have a specific polarity and voltage to be safe and effective.

Members of the tDCS community usually "draw heavily on scientific knowledge" while applying the technology, but that is not enough to rely on to ensure safe consumer use.

Still, even without regulations, tDCS can be widely implemented for medical purposes because of it is used in a systematic and controlled way by trained professionals.

Once the appropriate regulations are in place, though, tDCS opens up huge opportunities for psychiatric treatment and personal growth. It can be used not only to treat mental illnesses, but to increase individual self-control and potential among those who are "normal" as well.

The most exciting part of tDCS is not the benefits that it can offer right now, but what it means for the future. Too much of the human mind has been outside of our control throughout history, but the development of new neurotechnology can give us control of ourselves so that we are no longer slaves to nature.

Waitlisted for a College Class? Here's What to Do!

Dealing with the inevitable realities of college life.

Course registration at college can be a big hassle and is almost never talked about. Classes you want to take fill up before you get a chance to register. You might change your mind about a class you want to take and must struggle to find another class to fit in the same time period. You also have to make sure no classes clash by time. Like I said, it's a big hassle.

This semester, I was waitlisted for two classes. Most people in this situation, especially first years, freak out because they don't know what to do. Here is what you should do when this happens.

Whether you met your new love interest online, through mutual friends, or another way entirely, you'll definitely want to know what you're getting into. I mean, really, what's the point in entering a relationship with someone if you don't know whether or not you're compatible on a very basic level?

Consider these 21 questions to ask in the talking stage when getting to know that new guy or girl you just started talking to:

Challah vs. Easter Bread: A Delicious Dilemma

Is there really such a difference in Challah bread or Easter Bread?

Ever since I could remember, it was a treat to receive Easter Bread made by my grandmother. We would only have it once a year and the wait was excruciating. Now that my grandmother has gotten older, she has stopped baking a lot of her recipes that require a lot of hand usage--her traditional Italian baking means no machines. So for the past few years, I have missed enjoying my Easter Bread.

Top 10 Reasons My School Rocks!

Why I Chose a Small School Over a Big University.

I was asked so many times why I wanted to go to a small school when a big university is so much better. Don't get me wrong, I'm sure a big university is great but I absolutely love going to a small school. I know that I miss out on big sporting events and having people actually know where it is. I can't even count how many times I've been asked where it is and I know they won't know so I just say "somewhere in the middle of Wisconsin." But, I get to know most people at my school and I know my professors very well. Not to mention, being able to walk to the other side of campus in 5 minutes at a casual walking pace. I am so happy I made the decision to go to school where I did. I love my school and these are just a few reasons why.
