Network causality, axonal computations, and Poffenberger

All brain operations are implemented by networks of neurons. Unfortunately, the networks underlying even the most elementary brain operations remain elusive. This is due to the complexity of the networks, their heterogeneity, and to the multiple computations performed by the axons. Poffenberger's paradigm is one example of a simple task aimed at characterizing the temporal properties of an interhemispheric network which has remained elusive to this day.
