Simulated rippleβbehavioral data must be constrained by reported parameters, not invented wholesale. Three reported anchors define defensible ranges: state-dependent PPC ripple rates (NREM 0.5Β±0.2/s; wake 0.1Β±0.02/s; REM 0.01Β±0.04/s) ; arousal modulation of human hippocampal ripples (highest in NREM, lowest in wake, anterior > posterior) ; and cross-hemispheric amplitude synchrony vs weak phase synchrony .
Simulation parameters: log-normal event timing (ΞΌ, Ο fit to rates above), 146 Hz carrier with Β±5 Hz jitter, 53Β±20 ms duration, 13.5Β±1.9% hippocampalβPPC co-occurrence within Β±50 ms . Behavioral coupling: pre-training baseline = control group; learning sessions scale coupling strength (p=0.02) .
Coding pipeline (Python): numpy RNG for event trains; scipy.signal for 100β250 Hz bandpass + Hilbert envelope; ripple detection at 2β4 SD threshold (method-sensitive: 80β160 Hz bands differ across studies ); pingouin PLV for phase synchrony; TOST for equivalence .
Blindspots: epilepsy cohorts limit generalizability; detection thresholds bias event counts; simulations are illustrative, not observed data.
