Enkephalin constrains fear learning via volume transmission to the lateral amygdala

Roger Wang, Joanna Oi-Yue Yau, Muskaan Kalra, Sophia Gilchrist, Abbey Livermore, Gabrielle C. Gregoriou, Merle Schennink, Cesar Moreno, Rakulan Santhakumar, Neda Rafiei, Zian Hao, Julianne Estrella, Thea Thomsen, Emilie Hartvig, Maria Capertonova, , Elena E. Bagley

This study shows that enkephalin released in the amygdala during fear learning suppresses dopamine release, thereby constraining fear memory formation.

Opioid withdrawal abruptly disrupts amygdala circuit function by reducing peptide actions

Gabrielle C. Gregoriou, Sahil Patel, Sebastian Pyne, Bryony L. Winters, Elena E. Bagley

The paper shows opioid withdrawal reduces peptide activity in the amygdala by increasing neprilysin via PKA, disrupting synaptic transmission and potentially leading to compulsive drug use.

Brief optogenetic inhibition of rat lateral or ventrolateral periaqueductal gray augments the acquisition of Pavlovian fear conditioning.

Neda Assareh, Elena E. Bagley, Pascal Carrive, Gavan P. McNally

This study inhibits rat lateral and ventrolateral periaqueductal gray neurons during fear conditioning and finds it enhances fear learning and defensive responses.
