A Cognitive Model Based on Neuromodulated Plasticity

Figure 1

The architecture of the cognitive model. The model includes 3 main modules: sensory module, action module, and memory module. Thus, the interactions between agents and environment, that is, stimulus and response, are transferred as the information flows from sensory module to action module, signifying the sensorimotor system. Besides, VTA dopaminergic neurons and learning mechanism work together as the learning system to modify the synaptic weights between working memory and action module. All the above, the agent and the environment, compose a close-loop system.
