Before revision:  The controller is unique in the sense that (1) all data are encoded and processed by a spiking neural network (SNN), and (2) by mimicking the associated brain areas' connectivity , the SNN required no training to operate.
After revision:  The controller is unique in the sense that (1) all data are encoded and processed by a spiking neural network (SNN), and (2) by mimicking the associated brain areas' connectivity , the SNN is biologically interpretable and requires no training to operate.
