Parallel circadian-like oscillations in LTP and excitation inhibition balance in mouse CA1 reverse direction after puberty

Gonzalo Valdivia, Cristian Moreno, Kaiwen He, Darwin Contreras, Trinh Tran, Anthony D. Ramnaugh, William Xu, Altagracia Contreras, Diego Carlos Fernandez, Daniel Severín, Samer S Hattar, Michela Gallagher, Alfredo Kirkwood

The paper shows that LTP and E/I ratio oscillate with the light-dark cycle in mouse CA1, reversing direction after puberty.

Daily oscillation of the excitation/inhibition ratio is disrupted in two mouse models of autism

Michelle Bridi, Nancy Luo, Grace Kim, Benjamin J Menarchek, Rachel A. Lee, Bryan A. Rodríguez, Daniel Severín, Cristian Moreno, Altagracia Contreras, Christian Wesselborg, Caroline O’Ferrall, Ruchit V. Patel, Sarah J. Bertrand, Sujatha Kannan, Alfredo Kirkwood

The paper examines daily oscillations of the excitation/inhibition ratio in two mouse models of autism and finds disruptions in oscillation patterns rather than overall ratio levels.
