It's time: A commentary on fear extinction in the human brain using fMRI

Neuroscience and Biobehavioral Reviews

Abstract

The recent meta-analysis by Fullana et al. (2018) is both timely and significant, providing a vital milestone towards understanding the neural networks involved in threat extinction in humans. Fullana et al. (2018) examined both threat extinction and recall separately using sophisticated meta-analytic methods based on raw contrast maps. Importantly, the meta-analysis highlighted a lack of consistent activation across studies for key neural "players" in the threat extinction circuit: the amygdala and ventromedial prefrontal cortex (vmPFC). In the current commentary, we highlight reasons for which this key circuitry may not have resulted from this meta-analysis, and call for a 'gold standard' in the examination of threat extinction using fMRI.

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.
