Recent research suggests that the mediodorsal (MD) thalamus may "amplify the connectivity (signaling strength) of just the circuits in the cortex needed for the current context. This helps the flexibility (of the mammalian brain) to make complex decisions by wiring the many associations on which decisions depend into weakly connected cortical circuits". Researchers founds that "enhancing MD activity magnified the ability of mice to "think". This lowered by more than 25 percent their error rate in deciding which conflicting sensory stimuli to follow to find the reward".
