Abstract
Eye blinks elicited by a mechanically produced tap to the glabella (the flattened area between the eyebrows) are monitored by a device that projects low-intensity infrared light, which is reflected from the eyelid and detected by a phototransistor. Appropriate filtering and decoding circuitry insures reliable tracking of responses. Comparison of the optical eye blink monitor with a minitorque potentiometer monitor showed the two devices to yield similar recordings.

The development of these devices occurred during the course of a research project supported by NIH Grant HD 10511. We wish to thank Alan Taren for his early contribution to the design of the circuits for the optical detector. We also wish to thank Coulbourn Instruments, Inc., for suggesting modifications to improve those circuits.
