What Main Advantage Do Both Drosophila and C

Question

What main advantage do both Drosophila and C. elegans provide as an animal model in neuroscience?
A) They have small neurons from which it is easy to record activity during a behavior.
B) They are good for precise genetic manipulations that link the functions of specific genes or neuronal populations to the development and function of the nervous system.
C) They have large, identified neurons that are easy to record from electrophysiologically.
D) The connections of all the neurons have been mapped.

Accepted Answer

Both Drosophila and C. elegans have very small neurons. Although all of the neural connections have been identified in C. elegans, this is not the case for Drosophila.
