1. What is the electrode measuring?
The electrical current in the neuron. Voltage against time.
2. Why use leeches in neurophysiology experiments?
They have a simple nervous system, which obey many of the samerules as complex ones like ours, so discoveries in simple systemsmay help us to better understand ourselves.
3. What is the difference between a sensory and a motor neuron?
A sensory neuron takes the impulse from the receptors to the CNS,and a motor neuron takes the impulse from the CNS to the effectors(muscles or glands).
4. Do you think a leech experiences pain? What is pain?
I think all things experience pain. Pain is a typical sensory experience that may be described as the unpleasant awareness of a noxious stimulus or bodily harm.
5. What were the two most interesting things about doing this lab?
The information about the leaches, and finding the neuron.
6. Anything you found confusing or didn't like about the lab?
I found the lab quite boring. Interesting, but boring.
