Short communications: An on-line display of single-unit data

The purpose of this short conlmunlication is to describe a simple relatively inexpensive technique for the on-line display of single-unit neurophysiological data. The dot display is a compact method of viewing single-unit activity in response to repeated stimulus presentations. With a quick scan, one can answer such questions as: Does the unit respond? Is the response stable or is it changing? What is the temporal pattern of response?
