Fig. 4. Application of a mushroom body-inspired spiking network for navigation control in a roving robot through sequence learning. (a) Block scheme of the architecture; (b) Activity generated in the context layer when the sequence A-B-C-D is acquired and the different sub-sequences generated are learned by the network. The red circles represent the active neurons. (From [14], with permission ©2018 Springer Nature). 24 IEEE Instrumentation & Measurement Magazine December 2022
