Figure Lengend Snippet: Results of Alpha Wave Experiment. A. Real-time analysis in Backyard Brains SpikeRecorder software showing alpha waves (10 Hz, arrow) occurring during the eyes closed condition. B. Representative trace of one event, marked by the “closed” event marker (top). The representative trace was filtered and colored to highlight analyzed regions (below). C. Differences in frequency power for eyes open (yellow) and eyes closed (orange) conditions (left). Plot showing the ratio of alpha power in eyes closed/eyes open conditions for all events, shown as dots (middle). Arrow identifies the event shown at left. Average change in alpha power per participant shown as bar. Histogram showing the change in alpha power for all recorded events (right).
Article Snippet: The open-source software package SpikeRecorder (Backyard Brains, Ann Arbor, MI) was used to visualize and analyze the signal in real-time to identify any noise or signal quality issues.
