This is an ultra violet image of the neuron with dye showing the shape of the sensory neuron.
1. What is the electrode measuring? Transmembrane potential, also called membrane potential.
2. Why use leeches in neurophysiology experiments? Relatively small number and the large size of the neurons have have made the leech popular with neurobiologists.
3. What is the difference between a sensory and a motor neuron? Sensory neurons send information from PNS to CNS. Motor neurons recive information from the CNS that produces a response.
4. Do you think a leech experiences pain? What is pain? Yes, because the leech has has neurons. Pain is a response to stimulation.
5. What were the two most interesting things about doing this lab? Producing an electrical response to the neuron and the dissection process.
6. Anything you found confusing or didn't like about the lab? I didn't find this lab confusing at all, it was fun!
