| Ratna Angela Sarabdjitsingh, Julie Jezequel, Natasha Pasricha, Lenka Mikasova, Amber Kerkhofs, Henk Karst, Laurent Groc, Marian Joël. Ultradian corticosterone pulses balance glutamatergic transmission and synaptic plasticity. Proceedings of the National Academy of Sciences of the United States of America. vol 111. issue 39. 2015-04-30. PMID:25225407. |
