LEECH NEUROPHYSIOLOGY LAB: 1. What is the electrode measuring?
Impulse activity of the neurons. 2. Why use leeches in neurophysiology experiments?
Because the nerve structures are very large in comparison to other animals. 3. What is the difference between a sensory and a motor neuron?
A sensory neuron sends impulses based on some external input where a motor
neuron is to move a muscle.
4. Do you think a leech experiences pain? What is pain?
In this experiment, no due to it is a cyber leech. But in the real world I would say,
yes otherwise why use anesthesia on the leech. Unless it is to keep it from
moving as it is being dissected. 5. What were the two most interesting things about doing this lab?
Finding the different neurons and seeing different impulses each one had. 6. Anything you found confusing or didn't like about the lab?
No, I found it to be very straight forward.
