``Modeling the Nervous System: Reaction Time and the Central Nervous System,'' by Brindell Horelick and SinanKoont,UMAP67. The module models the process by which the central nervous system reacts to a stimulus, and it compares the predictions of the model with experimental data. Students learn what conclusions can be drawn from the model about reaction time and are given an opportunity to discuss the merits of various assumptions about the relation between intensity of excitation and stimulus intensity.

In Projects 2–5, complete the requirements of the designated UMAP module (see enclosed CD for UMAP modules).
