Epigenetic regulation of mirror neuron development, and related evolutionary hypotheses
Abstract
This chapter offers a brief review of theories on mirror neuron development, highlighting different models. These models focus on either the role of genetic mechanisms or the contributions of experience and of learning processes in shaping the brain circuits involved in action–perception coupling. As an alternative, the chapter proposes an epigenetic model for mirror neuron development, explaining how such a model can help to elucidate, within a unifying explanatory framework, the emergence, diversity, and functional reuse of mirror neurons. Lastly, a related evolutionary scenario is sketched in which epigenetic regulation, genetic assimilation/the Baldwin effect, and niche construction play crucial roles in mirror neuron evolution.
