Quantum Contact (H2): EEG-Linked Micro-Coherence in Double-Slit Signals — Bilingual EN/ES

Bilingual (EN/ES) paper reporting Hypothesis H2 of the Quantum Contact project: EEG-linked micro-coherence in double-slit sensor time series. The study tests whether high EEG Attention/Meditation states correlate with reduced micro-variability (rolling standard deviation) and increased coherence between sensors, using Spearman correlation with a one-sided permutation test and selectivity control (S1 as control). Includes methods, results, discussion, and dataset-based analysis for the recorded sessions.
