An investigation of low-level stimulus-induced measures of driver drowsiness
… and response variables could be used to detect eyelid closure associated with drowsiness, and. to provide ‘potential measures of driver· drowsiness. In. the study, eyelid closure was defined as the measurement standard of drowsiness. Eyelid closure, in studies conducted at Duke University, was a …

Forces Generated by Cell Intercalculation Tow Epidermal Sheets in Mammalian Tissue Morphogenesis
… late mammalian development by studying embryonic eyelid closure in mice, a process in which an epithelium locally reshapes, expands, and moves over another epithelium. Using a combination of lineage tracing and genetic ablation facilitated by ultrasound-guided lentiviral injection, I establish …

Performance and alertness of railroad engineers on long duration trips
… of performance. Objective (percentage eyelid closure and psychomotor reaction time) and subjective (self reported fatigue, workload, and stress) were used to provide measurement of alertness. No significant result was found when comparing the performance and alertness measures between …

Experimental evaluation of subjective ratings of drowsiness and development of drowsiness definitions
… that a regression model can be developed using eyelid closure measures, simple EEG measures and simple heart-rate measures to predict performance impairment due to drowsiness.

Tear film structure of the contact lens wearer
… induced localised lipid thickness increase. Eyelid closure was seen to compress the lipid film and instillation of saline broke up the lipid film. It can be seen that the pre-soft lens tear film usually possesses a thin superficial lipid layer and an aqueous phase of limited dimensions. On …

Higher Order Conditioning of the Eyeblink Reflex
… of the US. A predictive blink is such that eyelid closure is maximal at the time of expected air puff delivery. Physical and pharmacological manipulation experiments have determined that this behaviour is dependent on the cerebellum, and theoretical accounts based on the structure of the …
