  "account": "A study compared the continuous wavelet transform (CWT) and short-time Fourier transform (STFT) methods for analyzing oscillatory potentials in electroretinograms. Researchers analyzed FFERG recordings from multiple cohorts, including rats, mice, and humans with diabetic retinopathy. Both methods were validated using synthetic OP-like bursts. CWT revealed distinct time-frequency patterns and disease-specific OP alterations, exhibiting improved temporal localization and frequency resolution. In contrast, STFT merged transient features and was more susceptible to noise. The CWT-derived dominant-frequency differences reached significance across all models, while STFT differences only reached significance in rats. CWT also resolved two bursts separated by 15 ms but STFT did not. Overall, CWT provides a robust evaluation of OPs, preserving transient OP time-frequency structure in clinical and experimental settings. This analysis may improve the characterization of inner retinal dysfunction in preclinical rodent models and diabetic retinopathy patients.",
  "summary": "Purpose: To compare continuous wavelet transform (CWT) and short-time Fourier transform (STFT) analyses of the oscillatory potentials (OPs) of the dark-adapted full-field electroretinogram (FFERG). Methods: FFERG recordings from Royal College of Surgeons (RCS) and healthy Brown Norway (BN) rats, wild-type and Atoh7 enhancer-knockout (KO) mice, and patients with diabetic retinopathy and healthy…",
