“I think it is possible for novices and high school students to publish papers (and it is the dream and goal of our team)… That is why we are planning an experiment. We want to publish with a school in Santiago, Chile, collaborating with second and third year high school students. We are collecting data on electrical signals in plants… If it works, we will tell you…”
Dear readers, 21 months after writing this, the day has arrived. We did it! Our paper recently appeared in the academic journal “Plant Signaling and Behavior” about our experiments in electrophysiology in plants, with 5 high school students as the first authors. You can read the paper here.
Electrical signals in plants? What? Yes, it is understudied and often misunderstood, but plants do have signals similar to the electrical signals we have in our hearts, muscles, and brain. However, they are much slower (1,000-15,000 times slower). But what are they for? In the famous examples of the venus flytrap and the sensitive mimosa, the electrical signals coordinate their fast movements, but electrical signals also exist in plants that do not move quickly, such as tomatoes, chili peppers, basil, etc.
One of the functions of electrical signals in plants is as an alarm signal. For example, if a herbivore is eating a plant, an electrical signal passes through the branches saying “we are under attack” and the plant can synthesize bitter compounds so that the leaves taste bitter. A plant cannot escape when under attack, and it has the problem that it is “stuck in place forever” (i.e., it cannot run away from a threat, or fight physically), but there are protection systems and defenses (thorns, poisons, production of bitter compounds, etc.).
As electrophysiology in plants is understudied, we wanted to further investigate electrical signals in plants that do not necessarily move rapidly. And with that idea, we began to work on an ambitious project with the (high school) Colegio Alberto Blest Gana (CABG) in San Ramón, Santiago.
But before discussing the results, we must give a little more context about the scientific publication process.
Start the presses! Backyard Brains has a new publication! Our Neurorobot paper is titled “Neurorobotics Workshop for High School Students Promotes Competence and Confidence in Computational Neuroscience.” You can read the article in its entirety on the Frontiers in Neurorobotics website–because we believe neuroscience knowledge is for everyone, and no one should have to pay for access! The paper details our recent work developing the methodologies essential for making neurorobotics accessible in high school classrooms.
We began the Neurorobot project in 2018, when notable neuroscientist Christopher Harris joined the team with his gaggle of “brain-based rugrats” in tow. The Neurorobot aimed to bring neurorobotics more enticing to high school learners, and we quickly started to brainstorm (pun intended!) how we would implement such experiments in schools.
The Neurorobot Workshops
Chris ran the workshop at 2 high schools, sharing his 1-week Neurorobot workshop with nearly 300 students total. The students piloted the Neurorobot App developed for controlling the bots, and were able to provide feedback on the successes and shortcomings of the workshops.
The workshops were targeted to give students a base of knowledge and increase their confidence on the scientific topics studied. Both prior to and after the week-long sessions, students were presented a quiz, and their responses were analyzed for retention and comfort level. We found a significant improvement on all content questions, showcasing the effectiveness of our learning tools.
The Neurorobot Fellowship Project
If you recall, one of our fellows spent his summer working on the Neurorobot project. Ilya worked on coding the machine learning and computer vision aspects of the bot. Throughout the summer, he made progress posts, which can be found below:
There is nothing like hands-on application to showcase room for improvement, and our Neurorobotics Workshop definitely did so! We ran into some unexpected issues and tried to adapt on the fly, and we are so excited to keep this momentum going. Based on our successes, we hope to pilot more Neurorobotics programs in the future! Is your school interested?

Hot off the presses! Read all about it! Mantis Shrimp Wrangler Extraordinaire Dan has been published!
Backyard Brains Senior Fellow Dan Pollack has had his research published in JUNE, the Journal for Undergraduate Neuroscience Education: “An Electrophysiological Investigation of Power-Amplification in the Ballistic Mantis Shrimp Punch.” The paper offers a rundown of Dan’s research, culminating in a template laboratory exercise for use in classrooms, studying the electrophysiology of power-amplified limb movement in arthropods, with a specific focus on mantis shrimp strikes. How do mantis shrimps punch so hard, and how can we study the phenomena in the classroom?
