Description from the Website: Record electrical activities of individual neurons while you deliver mechanical stimulus to the attached skin. Inject fluorescent dyes into the neurons to visualize their morphology. Identify the neurons based on the morphology and the response to stimuli, comparing them to previously published results. This lab is less intellectual challenging compared to the other four virtual labs (the immunology, transgenic fly, bacteria identification, and cardiology lab). However, for students without experiences in dissection class, this virtual lab can be a good tour. Moreover, the glossary provided from this lab can be helpful for instructors in preparing the lessons of neurophysiology. Some features in this lab: 1. Although the first few stages are very procedural and can be finished by plainly following the instruction, please read the notebook window to understand the meaning of each step. 2. Probe and identify ganglion sensory cells is the most crucial step in this lab, so please read the notebook carefully. 3. There is no formal ending of this lab, you can repeat testing for different cells. 4. One problem I have is that I can't find the explanations for these different cell types in "Atlas".
