given the fact that the highest brain concentrations of iron are found in dopaminergic structures ( see 42 for review ) , and the essential role of intact dopaminergic systems to attentional and learning processes ( 15b,30 ) , the resultant behavioural changes due to the reduction of dopaminergic activity in iron-deficient animals may go some way to explain the adverse effects on cognition , behavioural patterns , learning and attention , event-related potentials ( erps ) and eeg changes reported in iron-deficient children ( 19-28,30 ) .
