132. Adapting the Behavioral ‘Human Intruder Paradigm’ to Probe Neural Threat Processing Across Species

Defensive responses to threat are highly evolutionarily conserved. Here, we conduct a cross-species study to examine the neurocircuitry mediating threat processing in youth and non-human primates (NHPs) using a novel adaptation of the Human Intruder Paradigm (HIP; behavioral task developed in NHPs) for functional imaging.
