Microprocessor-based system for spike and eye-movement data acquisition and storage

A simple system for simultaneous recording of eye position and spike activity during on-line experimentation is described. The system is based on a relatively inexpensive and widely distributed personal computer. While the hardware is configured from commercially available products, the software has been developed in our laboratory. Data acquisition is controlled by a few routines whose logic is outlined, together with the main limitations and the possible improvements of the system itself.
