This represents a simple (but historically important and well recognised) example of an oscillatory neural population model, convenient here for ease of introduction, analysis and simulation.
Brenner also chose it as it is easy to grow in bulk populations, and convenient for genetic analysis.
While a 10-mm TST cutoff for all populations is convenient, it feels simplistic given the known variation in nontuberculous mycobacteria exposure both between countries and within the United States (7) and the likely high coverage of Bacillus Calmette-Guérin vaccination in the foreign-born population.
