cones and showing limited integration at 3 months post grafting (data not shown). Those data are in contrast to our in vitro co-culture work where rapid functional integration and phenotypic maturation was readily achieved. In sum, this study provides a framework for the generation of distinct ventral prosencephalic neuron types that can be used to study various aspects of development and serves as a powerful in vitro platform to study dysfunction of specific neuron types implicated in a myriad of neuropsychiatric diseases.
