• For studying:

— Synaptic transmission

— Nerve conduction

• Applications include:

— Vagus nerve

— Cervical ganglion

The HSE-HA Marsh Ganglion Bath is intended to test the action of drugs on the synaptic transmission or nerve conduction in the vagus nerve or the cervical ganglion. The bath is an open-top Perspex bath which is divided into three chambers by two sliding separators. Each of these separators consists of a lower and an upper part with a cutout to allow the nerve to pass through. The chambers are sealed against each other with Silicone paste. The first chamber contains two platinum electrodes for stimulation. In the second chamber the solution is fed in close to the bottom of the chamber and drawn off at the surface. The Marsh Ganglion Bath includes the necessary components to produce two plastic recording electrodes to interconnect the recording chamber and electrode with the PHDA headstage amplifier. The prepared electrodes can be used for up to two weeks （with proper storage） to record extracellular potentials from the nerve preparation. In addition a stimulator, electronic equipment and an amplifier with high-impedance input and a peak height detector （PLUGSYS module PHDA） is required
