Teacher Feature: Jess S.’s Superb Teacher Research!

With our impending (PAID!) Summer Research Experience for Teachers (RET), based on our previous successful Summer Research Fellowships, we wanted to highlight the successes of our pilot teacher for this upcoming program.

Meet Jessica S., Neuroscientist, Plant Scientist, and Pea-Pod Costume Designer Extraordinaire!

We all had goofy costumes featuring neuroscience research themes for the 4th of July Parade…

Jess participated in the Summer of 201’s undergraduate research fellowship as our first teacher fellow!

From Jess’s first blog post, detailing her research experience:

“Hi! I’m Jessica, a high school Biology/Anatomy&Physiology/Marine Biology/Forensics teacher in southern California.

“I’m the only high school teacher in this summer Fellowship of the Brain but hopefully I’ll make a good enough impression so they’ll invite more teachers in the future… after all, we ARE the market.”

Jess’s grit and hustle led to a successful poster presentation at the end of the summer, and then she began transforming her research into a curriculum for her students!

Then, the following summer of 2019, Jess joined the International Research Fellowship to continue her research, to perform new (pedagogical) research, and preparing articles for publication – which have been accepted and will be published soon!

For a deeper look at her journey, and for a taste of what you might experience during your summer RET, check out all of Jessica’s Blog Posts:

BYB Needs You! Seeking Neuroscience Experiment Intern

Neuroscience Experiment Intern Wanted
(Downtown Ann Arbor)

Compensation: $15/hr based on 40-hour work week
Employment type: full-time internship

Backyard Brains is seeking a neuroscience intern to continue ongoing experiments!

You:
-A STEM undergrad, currently taking a break from the classroom. (Recent grad or gap year preferable)
-Passionate about scientific discovery and designing innovative, impactful experiments
-Experienced in or excited by a future of scientific outreach
-Able to guide a project through every step and take initiative when help is needed
-Looking forward to being a Neuroscience ambassador!

-Work in our Ann Arbor office during normal business hours (no parking on-site)

Our experiments have been featured in 9 TED talks and numerous popular science TV shows, such as White Rabbit Project and Bill Nye Saves The World. Your work will provide a basis for further research and even be included in peer-reviewed journal articles (authorship!).

To apply:
Please send your CV and cover letter including your research experience (if any) to hello@backyardbrains.com. Tell us why you are interested in applying for an internship at BYB!

We Are:
Backyard Brains is a DIY Neuroscience company devoted to bringing the brain to everyone! Because everyone has a brain, that complex but extremely fascinating puppet master of the body. We need more people interested in studying the brain because 20% of the world will have a neurological disorder… and there are no cures! Historically, you need to be a graduate student with funding at a major university to study the brain, but not any more! Backyard Brains wants to help everyone be a neuroscientist! We provide affordable neuroscience experiment kits for students of all ages to learn (hands-on) about electrophysiology. Now everyone from schoolchildren to grad students and every grade in between can experiment with similar tools used by real neuroscientists worldwide! What will you discover?


Getting Started with the Muscle SpikerShield Pro

Hey everyone! I’m Pablo, a junior from Nido de Aguilas High School in Santiago, Chile. In my free time, I like to doodle and run.

My project is a multi-channel version of the experiment that my colleague and friend Cristian developed: it consists of using the SpikerShield Pro’s ability to get data from multiple channels to create a musical instrument. In this instrument, flexing a muscle is analogous to playing a key in a keyboard. Obviously, the amount of channels limits this keyboard to six notes, but according to my limited musical knowledge, this is enough to create a coherent melody. In fact, the Arduino program currently has four settings which can be accessed using the red button: Mary Had a Little Lamb, Frere Jacques, major pentatonic scale and the minor blues scale. All the notes are in arrays with six elements, each corresponding to a channel. To add more possibilities, holding the white button in the board makes all the notes in the current setting one octave higher. You can download my code here.

The “loop” part of the code works by reading the red button, white button, and all six channels. First, it decides which set of notes to use for that iteration of the loop, which is controlled by the red button, then it checks if the white button has been clicked, which affects the pitch of the final note it plays. The last step is to decide which tone to actually play, which the code does by selecting the largest reading of all the muscles. Now, you might be thinking that playing music with two vastly different muscles, say your forehead and your forearm, will never work because a signal from the forearm will always be bigger than the signal of even the strongest forehead flex. However, the SpikerShield Pro can control the gain from each individual channel (the little white knobs) which can make a channel more or less sensitive to a signal, so every muscle has a fair chance of being played.

One challenge I faced when I developed this project is the lack of documentation of this particular product for novice programmers. Most of the times I’ve played around with an Arduino, I’ve relied extensively on the built-in tutorials and online resources, but this time I only had the board’s schematic, which at first glance bears a closer resemblance to black spaghetti than a discernible circuit and the default program which sends the signals from the board to Spike Recorder. Running the aforementioned program was not a challenge, but reading the code, not being fully aware of what it was, proved to be confusing. I only started making progress once Tim Marzullo showed me an outdated sketch meant for this shield. However, with this project in the open, I doubt this is a problem other users will face; the heart of the code — presenting the sensor’s readings as an array and mapping those raw values to a usable scale — can be used for most projects.

The second biggest challenge was and still is, my absolute ignorance about music theory. I never learned to play an instrument, and the most complicated song I managed to play is “Hot Crossed Buns”, though that is probably a skill I’ve lost. I’ve always enjoyed music, but much like hot dogs, I preferred to enjoy the finished product rather than learning how it is made. After adding the melody of Mary Had a Little Lamb and Frere Jacques, I did not know what other songs to add. After a fair amount of research, I came upon pentatonic scales, which are comprised of five notes.

Though the musical aspect is worth examining, what attracted me more is its role in many musical traditions, ranging from the ancient Greeks to the Andes. During the 19th century, composers like Debussy used the simplicity of the scale to create a folksy in their composition, resulting in music like La fille aux cheveux de lin. Later on, rock, blues, and jazz artists adopted the scale as a tool for their respective styles of improvisation. I think this is the area where my particular instrument shows the most potential because it is only capable of playing one note at a time, and also because flexing muscles to create sound is very intuitive. However, this is a hypothesis I will let the reader confirm.
