  1. develop theory create simulation compare with empirical data test behavior in real world Principles Underlying the Construction of Brain-Based Devices Jeff Krichmar The Neurosciences Institute San Diego, California, USA

  2. Construction of an Intelligent Machine Following the Brain Based Model • Design should be constrained by these principles: • Active sensing and autonomous movement in the environment. • Organize the signals from the environment into categories without a priori knowledge or instruction. • Incorporate a simulated brain with detailed neural dynamics and neuroanatomy. • Engage in a behavioral task and adaptation of behavior when an important environmental event occurs. • Allow comparisons with experimental data acquired from animal systems.
