    Alcohol impairs smooth and saccadic eye tracking by increasing processing time and decreasing velocity, unlike marijuana. This study investigated alcohol

    Area of Science:

    • Neuroscience
    • Ophthalmology
    • Pharmacology

    Background:

    • Smooth pursuit and saccadic eye movements are crucial for visual perception.
    • Alcohol is known to affect cognitive and motor functions, but its specific impact on eye movements requires further elucidation.

    Purpose of the Study:

    • To investigate the effects of alcohol and marijuana on smooth pursuit and saccadic eye movement breakdown frequencies.
    • To determine the specific mechanisms by which alcohol impairs eye tracking.

    Main Methods:

    • Experienced alcohol and marijuana users tracked a horizontally oscillating spot.
    • Eye movements were recorded as oscillation frequency increased.
    • Smooth and saccadic eye movement cutoff frequencies were determined.

    Main Results:

    • Alcohol significantly reduced smooth and saccadic eye movement cutoff frequencies.
    • Low alcohol doses impaired smooth tracking, while saccadic tracking remained unaffected.
    • Alcohol increased central processing time for smooth tracking and increased latency for saccadic tracking.

    Conclusions:

    • Alcohol, but not marijuana, impairs both smooth and saccadic eye tracking.
    • Alcohol's effects on eye movements are likely mediated by central mechanisms in the brainstem and cerebellum.
    • Findings suggest alcohol increases processing time and alters velocity/latency in eye movement generation.
