A Biologically Inspired Computational Model of Basal Ganglia in Action Selection

Figure 3

Temporal activity of the neurons in each structure of the whole network in a default case, assuming that the input stimulus favors the second response. In this case, the basal ganglia gate the response associated with the higher input stimulus (i.e., the second in this case): the second neuron in the cortex is maximally active, together with the corresponding neuron in the thalamus. The Go and NoGo pathways are both active, but the imbalance induces the correct response to be gated. In this case, the STN activity is low, indicating that the network does not perceive any conflict situation in the cortex.
