Disentangling hippocampal and amygdala contribution to human anxiety-like behavior
Anxiety comprises a suite of behaviors to deal with potential threat and is often modeled in
approach–avoidance conflict tasks. Collectively, these tests constitute a predominant …

[PDF][PDF] Human hippocampus arbitrates approach-avoidance conflict
Animal models of human anxiety often invoke a conflict between approach and avoidance
[1, 2]. In these, a key behavioral assay comprises passive avoidance of potential threat and …

Hippocampal representation of threat features and behavior in a human approach–avoidance conflict anxiety task
A Abivardi, S Khemka, DR Bach - Journal of Neuroscience, 2020 - Soc Neuroscience
Decisions under threat are crucial to survival and require integration of distinct situational
features, such as threat probability and magnitude. Recent evidence from human lesion and …

Parsing the role of the hippocampus in approach–avoidance conflict
The hippocampus plays a central role in the approach–avoidance conflict that is central to
the genesis of anxiety. However, its exact functional contribution has yet to be identified. We …

Rodent models of anxiety have implicated the ventral hippocampus in approach–avoidance
conflict processing. Few studies have, however, examined whether the human hippocampus …

Dissecting the function of hippocampal oscillations in a human anxiety model
Neural oscillations in hippocampus and medial prefrontal cortex (mPFC) are a hallmark of
rodent anxiety models that build on conflict between approach and avoidance. Yet, the …

[HTML][HTML] Amygdala lesions reduce anxiety-like behavior in a human benzodiazepine-sensitive approach–avoidance conflict test
Background Rodent approach–avoidance conflict tests are common preclinical models of
human anxiety disorder. Their translational validity mainly rests on the observation that …

Neural substrates of approach‐avoidance conflict decision‐making
Animal approach‐avoidance conflict paradigms have been used extensively to
operationalize anxiety, quantify the effects of anxiolytic agents, and probe the neural basis of …
