    This study reveals Rapid Eye Movement (REM) sleep is a stochastic process, modeled as a semi-Markov process. Oculomotor analysis confirmed two independent REM entities, validated in zero-gravity.

    Area of Science:

    • Neuroscience
    • Sleep Science
    • Oculomotor Research

    Context:

    • Investigating the temporal dynamics of Rapid Eye Movement (REM) sleep.
    • Utilizing oculomotor frequencies as a proxy for REM-process analysis.
    • Applying quantitative methods to understand time-dependency in biological processes.

    Purpose:

    • To characterize the REM-process as a stochastic point process.
    • To model the occurrence of REM events using transition probability matrices.
    • To test a hypothesis on REM-sleep configurations in microgravity.

    Summary:

    • REM-sleep was identified as a stochastic point process.
    • A two-state, first-order semi-Markov process model described REM event occurrences.
    • Oculomotor patterns indicated two independent REM-sleep entities with distinct frequencies.
