How to teach this paper: ‘Behavioral time scale synaptic plasticity underlies CA1 place fields,’ by Bittner and Milstein et al. (2017)

Katie Bittner, Aaron Milstein and their colleagues found that cellular learning can happen over longer timescales than Hebb’s rule predicts. How long should we wait to teach students about this phenomenon?
