  • Analyzed data from rodent T-maze alternation tasks.
  • Investigated statistical limitations of existing experimental data.

    • Main Results:

    • Current electrophysiological recordings and analyses possess insufficient statistical power.
    • Meaningful comparisons between dynamic time warping and traditional analyses (Fourier, wavelet) are not yet possible.
    • Larger and cleaner datasets are required for advanced comparative analyses.

    Conclusions:

    • Existing experimental paradigms for studying prefrontal cortex function are statistically limited.
    • Dynamic time warping shows potential for analyzing neural synchronicity.
    • Future research requires improved data acquisition and larger datasets for robust conclusions on neural correlates of behavior.
