An integrated mini-computer system for the automatic control of pharmacological experiments and calculation of results.

A mini-computer system for the automation of pharmacological experiments and for the calculation, printing and storing of results is described. A link between the 1) control unit which powers the pumps, valves, etc., and 2) the computer which processes the digital data allows the synchronization of data collection with the time course of the experiment. Thus results may be immediately expressed in absolute (i.e. stimulus-induced change in tension, etc.) or relative (i.e. % change in response due to drug administration) terms.
