Architecture of the 200N (A) and 2N-DINASAUR (B) models. (A) The original version of DINASAUR with 200 nodes, inspired from Trappenberg et al. (2001) and previously described in Bompas and Sumner (2011). (B) The 2-node version of the model introduced here allows for a fair comparison with manual responses. It also has mutual inhibition, self-excitation and leakage, an endogenous signal that favours the target. It no longer contains a fixation node to keep neural activity stable before stimuli appear; instead this role is performed by common endogenous inhibition.
