Striatal output regulates the postnatal maturation of cortical circuits

Michael Janeček, Tara Deemyad, Yi-Chun Shih, Vicente Valle, Andrew D’Agostino, Michael Matarazzo, Megan S. Perez, Kyle D. Ketchesin, Susana da Silva, Rui T. Peixoto

This study shows that striatal output during early postnatal development affects the activity and maturation of the dorsomedial prefrontal cortex circuits in mice.

Early Postnatal Dysfunction of ACC PV Interneurons in Shank3B-/- Mice

Yi-Chun Shih, Lars Nelson, Michael Janeček, Michael Matarazzo, Andrew D’Agostino, Rui T. Peixoto

This study identifies early dysfunction in ACC PV interneurons and HCN channelopathy in Shank3B-/- mice, leading to circuit reorganization and impaired inhibition.

Late onset of striatal projection neuron hyperexcitability in Fmr1-/y mice

Lars Nelson, Michael Janeček, Michael Matarazzo, Yi-Chun Shih, Rui T. Peixoto

This study shows that striatal projection neurons in Fmr1 knockout mice develop normally but become hyperexcitable by postnatal day 60, with limited response to aripiprazole treatment.
