Schematic illustration of MNS in the macaque monkey brain.
Area F5 is connected with the inferior parietal lobule (areas AIP-anterior intra-parietal, PF and PFG). Within the frontal lobe, area F5 is connected with hand/mouth representations of primary motor cortex (Source: Craighero et al. [16]).

Overview of TGAR-HMM learning architecture.
The observed behaviour sequence is first arranged through topological map. This topological map is then used to update the state structure for estimating the optimal number of states and the transition probabilities among these states.
