Probe and Identify Sensory Neurons
This section simulates a real neurophysiological experiment that explores the leech's nervous system. You may want to review background on the Neuron, Resting Potential, Action Potential, and Voltage Display before starting the simulation.
![Several pieces of lab equipment are set up together. On the right is a dissection microscope, which is positioned over the dish holding the leech section. There are several tools to the left of the microscope. The tools are used to place a very fine glass electrode precisely into the leech neuron.](images/probe1/leech_step9a.jpg)
