Last year, we launched our “human human interface” allowing a connection between complete strangers to be built artificially, bypassing chance.
But there are those lucky people who don’t need a mechano-electrical connection, who say they simply “feel something” in the presence of another. Being in the same room together, subjects report feeling “warmer,” that there is a sort of “energy flow” and even sometimes stating “we are on the same wavelength.”
When giving talks to the public, we are often asked if we can find a way to detect this “energy” and “connection” between two people who are enamored with each other.
This connection, of course, is due the emission of love waves.
It a very elusive signal some unfortunate people spend a lifetime trying to experience, and we hereby announce our new R&D initiative to detect the emission of such waves.
This has been a long time in coming and has always been the master plan of Backyard Brains. We have developed amplifiers to detect neural activity in cockroaches, then muscle activity in humans, and, very recently, human heart, brain, and eye wave activity. These were merely prototypes giving us the technical skills required to detect the only signal we have really ever wanted to observe (and it is the most difficult to detect): the extramission of affection.
When people are with people they enjoy, many things happen in their body.
-Eye Contact Increase
-Heart Rate Increase
-Increased Blood Flow to Face
-Love Wave Emission
All of the above responses are recordable via current technology, save for, alas, the last, the love wave. Though the human body is itself an excellent love wave detector (this is the “energy” people often report feeling), detecting this signal “in transit” through the air is very difficult.
Below is the current state of our design:
Stay tuned of our efforts to detect this signal that so many of you have asked for. It has not escaped our notice that once we successfully detect and isolate the love wave, we can amplify and broadcast it over a range much greater than the two people emitting it. We will rebuild Wardenclyffe Tower, but this time, we will manifest Mr. Tesla’s true desire that he hid from J.P. Morgan. Instead of delivering global power, we will deliver global love.
With Love Waves amplified and spread across the planet, World Peace, the longing of so many religious leaders, shall finally be revealed. We haven’t a moment to lose.
“I have predicted electrical oscillations which were of such intensity that when circulating through my arms and chest they have melted wires which joined my hands, and still I felt no inconvenience. I have energized with such oscillations…”
My name is Greg McMurtry. I am a sophomore at the University of Michigan studying mechanical engineering, and I have been working with Backyard Brains for the past four months. Currently, I am working with cockroaches and their descending contralateral movement detector “DCMD” neuron. Current research suggests that this neuron is correlated with the detection of and reaction to approaching objects. To test this, we try to take a neural recording from this nerve using a BYB Spikerbox. We then attempt to stimulate the nerve by shining a flashlight at the cockroach to emulate a change in its visual field. My project has two main goals. The first is to develop and refine an experiment that teaches students about the cockroach’s vision and its DCMD. This experiment will be similar in nature to the neural interface surgery used to transform an ordinary cockroach into a RoboRoach. The second purpose of this project is to see how the insects react to certain approaching objects to gain further insight into what the DCMD neuron does and what its response to external stimuli reveals about insect vision.
The procedure used to conduct experiments on the cockroach’s DCMD required that the insect be placed on its back so that electrodes may be inserted through the neck into the DCMD neuron. These electrodes are then connected to the Spikerbox, which can detect any neural activity. In order to gain clear access to the neck, the cockroach’s head was initially anchored back using a piece of string and tape.
This anchoring process was extremely difficult, and it typically took anywhere from five to fifteen minutes to slide the string under the cockroach’s mandible, pulls its head back, and tape the string down without the head shifting during the process. After this process was completed, the cockroach was usually able to move its head into a position that made it very difficult to insert the electrodes. Even if it did not move its head into a difficult position, the cockroach was able to break free from the string and tape within ten minutes of being anchored, leaving a small time frame to conduct the actual experiment.
Frustrated by the difficulty of anchoring the roach’s head back, I began to think of alternative methods to do the same task. Drawing inspiration from the head immobilizers used by emergency services, I began to sketch potential concepts in my lab notebook.
After encouragement from the BYB team, I began designing a more precise model. I began by taking measurements of the cockroach at various points of its body, measurements of the cork, and measurements of the SpikerBox in order to determine the required dimensions for the holder.
When the to-scale model was sketched, I began designing the first model of the Head’s Up! Roach Holder using Sketchup. After printing and assembling the Head’s Up! Roach Holder, I tested it out immediately to see if it worked and if I would need to make changes.
It worked! I was excited that my initial design not only worked, but also far surpassed the string and tape method. It was able to lock both the cockroach’s body and head into place for over an hour, something that the simple tape and string was unable to do.
As a result of this completely immobilized state, I was able to place the electrodes in near perfect position. Initially, a steady beam from a flashlight did not evoke any bioelectrical response. When the flashlight was placed in strobe mode, faint popping sounds were heard coming from the Spikerbox. Upon further testing and combined with visual confirmation from the recordings from the Spikerbox app, these popping sounds were confirmed to be the DCMD neuron processing and reacting to the visual stimulus.
Though significant progress has been made with this project, there is still much more that has to be done. The Head’s Up! Roach Holder will most likely undergo slight revisions so that its height can be adjusted for cockroaches of varying sizes. Future testing will be done in order to qualify the response of the prep based on the electrode positions. The only problem I foresee is determining and verifying the optimal electrode position to get reliable and consistent readings.
Regardless of any possibilities that lie ahead, this research position will continue to be both interesting and rewarding. Check the blog for an update in April!
On January 1st, we received a New Year’s gift from another continent: Neuroscience tools and experiments made by a group of high school students selected from the 20 best rated schools of Iran. They were written lab reports, submitted for an interdisciplinary neuroscience competition that utilized our open source experiments with cockroaches as a resource for the kids to make their own research and inventions.We here summarize and celebrate their efforts, you can also download the original reports yourself. This is a result of our 3 year friendship with Mohsen Omrani, an Iranian neuroscientist, doing research in nearby Ontario, Canada. He acts as a community liason between the Iran Science communities and the wide network of scientists around the world (Every Iranian Neuroscientist we know seems to be a colleague of Mohsen).
Of note is that in Iran, students choose to follow a biology route or a mathematical root when they are in the 9th grade. There was an emphasis for each team to have students with both biology background and mathematics background so they learn to be able to communicate with each other. So what then did the students investigate?
To begin, a question we often are asked is: “Why Cockroaches?” Indeed this was also asked by members of the Allameh Helli 4 High-school: they submitted the hypothesis that the cockroach is the perfect “explorer” companion for a researcher, because of their access and survival in complicated and uncertain environments. In other words, they declare that roaches could become better tools than robots for scientists to reach unknown places. The main influences for this conclusion was the article “Line following terrestrial insect biobots” by Tahmid Latif and Alper Bozkurt .
The most remarkable thing about this competition is not that the students built their own tools for the experiments using open source resources, like schematics, code and design… but they made their own custom modifications to design different experiments from the ones we had made.
One excellent example of this is the Robo Roach version (a remote controlled cockroach) of Alireza Farzad, Behzad Haghgoo, Amir Reza Haji Anzehaei, Aria Hassanpour, Mohammad Reza Osouli of Allame Helli one High School.
They used an IR System to send a signal to a IR receiver circuit that’s connected to the cockroach antenna AND their cerci. We have only begun cercal stimulation, the Iranian students beat us to it! In words of the students:
“Cerci is a very sensitive organ which receives smallest movements of the air and warns the cockroach to run. We thought that cerci may have a low adaptation rate because it is directly related to its life being. By stimulating the cerci we make an illusion of danger and we make the cockroach run forward”.
Their results to this new experiment was that “ 3V potential difference is the best combination for cerci electric stimulation” and that the cockroach doesn’t adapt to the stimulation of the cerci, unlike the antennas that show strong adaptation properties.
Danial Zohourian and Amir Masoud Azadfar, from a different high school, focused on cerci stimulation only, coming up with a very useful table of results on how fast the cockroach goes (steps/ per second) according to voltage.
||Steps per Second
||10 steps in 7 seconds
||9 steps in 3 seconds
||12 steps in 4 seconds
||13 steps in 3 seconds
||10 steps in 5 seconds
||13 steps in 4 seconds
Interestingly, they had a different outcome than the students from Allame Helli one High School: they concluded that best stimulation is at 2 volts, not 3, and that cercal stimulation does adapt.
So what is the correct answer? Only that new experiments are necessary to understand why there are different results, and what improvements are important to obtain a more accurate conclusion. But as we have learned, the best experiments come from disputes between scientists that motivate each other to improve their work.
Regarding on this emphasis on possible errors to improve experiments, the writing of students Tarannom Taghavi and Nastaran Fatemi, from Kherad high school caught our attention. They tried to tackle the main problem of the Roboroach: the behvioral adaptation to the stimuli that controls the cockroach: “ If we can produce the signals in it’s ganglion and send it to the cockroach, there won’t be adaptation anymore. As we are creating the signals and sending it to its decision making center, we might be able to take control of cockroach’s decision making process.” They did this by recording roaches signal with a spikerbox and trying to send it back to the ganglia.
Interpretation of the electric signal obtained from the cockroach.
Although it wasn’t successful, coming up with this hypothesis to solve the main problem of RoboRoaches was impressively creative. And, as we noted, we really liked the focus of their paper in the mistakes that were made and how to make corrections for a future experiment: they were the only students that made emphasis on the importance of iteration, of making a lot of failed experiments that are patiently and constantly improved, before making any discovery. Thus our informal “Golden Cockroach” award goes to Tarannom Taghavi and Nastaran Fatemi.
Finally, we want to give a special mention to the only group that designed a new interface: a special cockroach treadmill to estimate the adherence of these insects legs:
Keep on inventing, Keep on discovering, our fellow young colleagues across the globe.
