Machine Learning Detection of Plant Bioelectric Responses to Human Eurythmic Gestures:

We recorded bioelectric activity from 2,978 plant samples across three species (basil, salad, tomato) using differential electrode pairs (leaf and soil electrodes) sampling at 142 Hz. Two trained performers executed three specific eurythmic gestures near experimental plants while control plants remained isolated. Random Forest and Convolutional Neural Network classifiers were applied to distinguish control from treatment conditions using engineered features including spectral, temporal, wavelet, and frequency domain characteristics. <b>Results</b>: Random Forest classification achieved 62.7% accuracy (AUC = 0.67) distinguishing eurythmy from control conditions, representing a statistically significant 12.7 percentage point improvement over chance. Individual performer signatures were detectable with 68.2% accuracy, while plant species classification achieved only 44.5% accuracy, indicating minimal species-specific artifacts. Temporal analysis revealed that repeated exposure plants exhibited consistently less negative bioelectric amplitudes compared to single-exposure plants.
