neurons | Shelley Sackier

I love learning about the brain.

I’m continually unearthing new research revealing fresh discoveries that must make the neuroscientists who discovered them leap up and down like seven-year-olds when you tell them you’re taking them to the local ice cream parlor for a double scoop.

Some of the studies are astonishing.

Most of the studies are encouraging.

All of the studies are in a version that is appropriate for a twelve-year-old to interpret. That’s pretty much the only way I will be able to absorb all of the astonishing and encouraging data. A neuroscientist I am not. But I do have a brain. And that’s about as much as we share in common—apart from the fact that I will leap up and down for a double scoop when offered as well.

The latest brain study I stumbled upon was all about memory creation. I can’t remember who authored the paper, or which university the research took place at—but that likely points toward exactly why I was out hunting for memory studies in the first place.

The study discussed two particular regions of the brain that need to speak with one another in order to create successful learning:

the hippocampus,

and the prefrontal cortex.

Apparently, if we are working on a task of learning to connect two objects to one another—like shoe and foot, or chair and table—our brain’s neurons are busily firing off. And, as a result, generate brain waves.

And also apparently, these two chunks of gray matter—the hippocampus and the prefrontal cortex—use two different frequencies to communicate whether or not we guessed correctly, in which case we’ll get a blue ribbon to sport, or whether we guessed wrongly, and are then seated in the corner of the room with a pointy shaped hat on our heads.

It all comes down to the oscillation of the waves.

Answering correctly—a thumbs up—makes the waves oscillate at a high rate referred to as the beta frequency (9-16 hertz), and a thumbs down results in a lower oscillation called theta frequency (2-6 hertz).

I’m pretty sure we should add a two thumbs down result in here for the general faction of teenage boys which typically operate at the lowest frequency setting of thunka (-3-0 hertz) just to be on the safe side of science.

If I can remember where I placed the study, I will petition the authors to include my data into their research.

The scientists documented brainwave frequencies while studying test subject animals. These critters were tasked to learn which two images should be connected to one another and which two images should not be coupled. This was done through trial and error. A reward was given to indicate a correct choice. It’s like when you try to teach your cat how to drive. The only way they will receive the reward of finally making it to their favorite acupuncturist on time is if they learn that they must insert a key into the car’s ignition and not a spatula.

Simple, right?

Choosing the “right” answers showed that the pathways between neurons were strengthening. And choosing the “wrong” answers weakened pathways. It was as if the brain was trying to communicate through the oscillation of waves which neural pathway should have a giant WELCOME sign at its entrance, and which should be choking with weeds, overrun with poison ivy and displaying a placard with a skull and crossbones.

And the hope is that now scientists will be able to utilize low voltage electrical stimulation to the brain to “speed up” the process of learning. And who wouldn’t go for that, right?

Soon we’ll all be able to put on a special hat, attach ourselves to the nearest electrical outlet, and begin the once arduous process of learning a language, conquering physics, or watching something like Seth MacFarlane’s film, A Million Ways to Die in the West. With a few tweaks of current control, you’ll be conversing in Chinese, building the next Mars rover, and hacking into production facilities with the intent to destroy wretched films in the nick of time just before they’re widely released for public consumption.

If nothing more, I’m incredibly encouraged by the research taking place and wholly support any studies that will not only retain the vital neurological pathways I’ve worked so hard to establish already, but potentially make it possible for me to go on learning new information that can only enrich and deepen my intellectual experience.

As a reward to myself for having made it through reading this particularly challenging study on cognitive function and its future, I’m heading out to the nearest, local ice cream parlor for a double scoop.

Now if I could only find where I put my spatula …
