Recording of nerve and muscle potentials by mechanical stimulation at the front end of an earthworm (Cobra3)

Principle and tasks

To work on the following themes by measuring nerve and muscle potentials:

• The difference in sensitivity of the front and rear ends
• The facilitation effect
• Conduction velocity and fibre diameter
• Synaptic depression

What you can learn about

• Nerve and muscle potentials
• Positive feedback
• Synaptic depression
• Synaptic facilitation
• Conduction velocity in median and lateral giant nerve fibres
