Increasing evidence suggests that it is not only the case that brain-based cognitive and emotional processes affect decision-making, but also that decision-making, actions and habits influence in turn the very structure and function of the brain by way of neural plasticity. This indicates that the interplay between brain and agency is made up of a complex feedback loop of reciprocal causality. The assumption that the causal relationship is one way –brain to behavior– results in unsatisfactory neuroscientific analyses of agency. I contend that taking into account reciprocal causality for the purposes of human enhancement is not only a matter of theoretical consistency, but also carries with it important practical implications. Top-down cognitive enhancement –through mind training techniques such as meditation– may have advantages over biomedical enhancement.
