Examining the role of the anterior and posterior orbitofrontal cortex in emotional regulation in the common marmoset (Callithrix jacchus)
… a paradigm testing the responses to a distal threat. The first experimental chapter confirmed that this effect is also present with an acute temporary inactivation of the antOFC. Inactivation of the pOFC produced a trend towards a similar anxiogenic-like effect. To elaborate on these findings, …

Targeting AMPA Receptor Modulation during Early Life Adversity: A Mediator for Threat Associated Memories
… for ELA is low. Yet, animal models of the threat response during development have given clues into ways in which early adverse experiences transition later in life. Our previous research has provided behavioral evidence that there are differences in infant and juvenile threat processing, …
