Lab Practical - Foxy - Global Potential of the Crab Nerve: Influence of Stimulation Intensity on the Amplitude of the Response of the Isolated Crab Nerve

Extract from the 1st STL syllabus:
Living systems use two main communication pathways:
- nervous communication
- hormonal communication

Scientific problem:
What are the characteristics of the electrical signals that make up nerve messages?
How are these messages emitted and encoded?
How is information transmitted from neuron to neuron?

Experiment goal:
Demonstrate that the nerve response amplitude is proportional to the intensity of the electrical stimulation.
Highlight the existence of a stimulation threshold.
