Key result
The vestibulo-ocular reflex compensating for heartbeat-induced head perturbations can detect human drowsiness in a stationary environment, with horizontal VOR parameters achieving 85.9% accuracy for awake states and 80.8% for drowsy states.
Why the study?
Whether the vestibulo-ocular reflex can detect drowsiness in stationary environments lacking exogenous head movements remained questioned.
Population
15 healthy participants (12 male, 3 female), average age 22±1.8 years.

The vestibulo-ocular reflex compensating for heartbeat-induced head perturbations can serve as an indicator of drowsiness in stationary environments.
Yamanaka et al. (2024) conducted an observational in Drowsiness (n=15). Drowsiness vs. Awake state was evaluated on Change in horizontal vestibulo-ocular reflex (VOR) gain and variability with increasing drowsiness levels (p=<0.001). The vestibulo-ocular reflex compensating for heartbeat-induced head perturbations can detect human drowsiness in a stationary environment, with horizontal VOR parameters achieving 85.9% accuracy for awake states and 80.8% for drowsy states.
