The measurement chamber for earthworm experiments is used in
neurophysiological experiments on intact worms. This involves stimulation of
the worm by electrical or tactile means and measurement of its action
potential. Worms remain uninjured and can be returned to their habitat after
completion of the experiment.

A cover with holes drilled in it allows worms to be secured transversely across
the apparatus without difficulty and two replaceable longitudinal securing
mechanisms prevent them moving along. Contact with the worms is via a long
line of electrodes which can be connected to the bio-amplifier via 2-mm
sockets and special cables or to the stimulus generator of the biomeasurement
interface. Tactile stimuli can be provoked through the hole in
the cover. The measurement chamber can be quickly and easily dismantled
after completion of the experiments.
