✦ Synopsis

The use of television systems to generate patterned stimuli for the examination of EPs has disadvantages due to the frame frequency of 50Hz of television sets. Because of this, changes in the pattern last 20 msec, with the result that the variability in EP latencies is larger than in the results obtained by projector systems. Furthermore, 50 Hz noise on the recordings, transmitted through the visual system, may be seen.

A system, controlled by a microcomputer (LSI-1 l/23 with appropriate peripherals) for conducting evoked potential (EP) experiments, is described. In each experimental trial, a stimulus is applied and multichannel EEG is sampled, displayed, and stored in an output file. Any required length of pre-and

## Abstract **BACKGROUND:** The potential use of plants as production systems to establish bioprocesses has been established over the past decade. However, the lack of efficient initial concentration and separation procedures affect the generic acceptance of plants as economically viable systems. I
