EducationNow that I’ve got the ear clip unipolar EEG set up, I’m finally ready to record. I have my subject wear two headbands: one around the head like a normal sweatband and one under the chin and over C3 like in my previous experiments. I had to do a quick test to get the polarity […] -
UncategorizedMany EEG experiments are done using 21 electrode helmets to gain better localization resolution. In our case, this will not be necessary. Since the secondary motor area generates the readiness potential, the strongest RP signal is found immediately over that region, contralateral to the side of the body performing the task. In our case, the […]

EducationBy Patrick Glover DETAILS A longstanding debate in philosophy focuses on the existence of free will. Do humans have some inherent moral agency, or are our brains just biological machines, subject to the same physical determinism as any other animal? Modern neuroscience can provide some insight to these questions, such as Benjamin Libet’s famous 1986 experiments […] -
Fellowship— Written by Milica Manojlovic — Aaaand the results are in! So, just a quick recap – we were hoping to get as much data on the way we process the Pinocchio illusion by measuring different behavioral outcomes as well as the EMG in three timepoints. As far as the behavioral measures are concerned, we questioned
EducationPh.D. student and friend of Backyard Brains, Brinnae Bent of Duke University, recently hosted a class for seniors participating in the “Osher Lifelong Learning Institute at Duke (OLLI at Duke).” With help from some colleagues at North Carolina State University, she put on an afternoon workshop in Electrophysiology for these lifelong learners. From its website, […]
UncategorizedThose of you in the Midwest, bring your families and friends to the Maker Faire at the Henry Ford Museum this weekend (July 31st and August 1st). Backyard Brains will be participating in this nerd paradise. Our exhibit number is 3534. Also, the “silent third” partner of Backyard Brains was recently highlighted by the […]
FellowshipCall for Undergraduates in Biology or Engineering Fields Do you have an interest in neuroscience? Do you like squids or dragonflies? Electrical, Mechanical or Computer engineering? Want to develop your own experiments and publish your results? Learn to communicate with the public? Maybe even all of the above? Then you’re in luck! The Backyard Brains Summer Research […]
FellowshipCall for Undergraduates in Biology or Engineering Fields: Are you a neuroscience nerd? Do you want to learn how the brains of animals like squids or dragonflies work? Is your background in Electrical, Mechanical or Computer Engineering? Want to develop your own innovative experiments and publish your results? Learn to communicate those stunning results with the […]
OutreachOn June 17th, the A2 Tech Trek took place in downtown Ann Arbor hosted by Ann Arbor SPARK. The purpose of the Tech Trek was for ‘Downtown Ann Arbor technology companies opening their doors to the public’. Over 50 companies participated in this event with close to 500 people pre-registered. Backyard Brains participated in this year’s […]![[Summer’16 Internship] Arduino, EEG, and Free Will: Measuring awareness times](https://cdn.hackaday.io/images/2015661470085560114.JPG)
EducationLibet had the subjects view an oscilloscope with a dot rotating periodically in a circle, and subjects were asked to retroactively report where the dot was when they first became aware that they were about to perform the voluntary task. He could then calculate the average latency between when the subject reported awareness and when […]![[Summer’16 Internship] Arduino, EEG, and Free Will: Three Channels!](https://cdn.hackaday.io/images/6218711468935472851.png)
EducationIt took a lot of tinkering, but I’ve finally performed the free will experiment using multiple electrodes on the scalp. The hardware setup was fairly simple. Take two more Heart/Brain shields, switch C7 for a 47µF cap on both, and stack them on top of the existing setup using headers. Make sure each shield has a […]![[Summer’16 Internship] Arduino, EEG, and Free Will: A big](https://cdn.hackaday.io/images/7529791467230878252.jpg)
InternshipI had been searching for a readiness potential for weeks, trying to sift through noise two orders of magnitude louder than the signal itself, with little success. This morning Greg, my research mentor, pointed out that since I’m using a bipolar electrode EEG, the op-amp is only magnifying the difference between the two leads over […]
