Distinct Activity Patterns of the Human Bed Nucleus of the Stria Terminalis and Amygdala during Fear Learning

Neuropsychology Review
Kelly LuyckLaura Luyten

Abstract

The amygdala and, more recently, also the bed nucleus of the stria terminalis, have been widely implicated in fear and anxiety. Much of our current knowledge is derived from animal studies and suggests an intricate convergence and divergence in functions related to defensive responding. In a recent paper, Klumpers and colleagues set out to examine these functions in a human fear learning procedure using functional magnetic resonance imaging. Their main findings were a role for the bed nucleus of the stria terminalis in threat anticipation, and for the amygdala in threat confrontation. Here, we provide a critical summary of this interesting study and point out some important issues that were not addressed by its authors. In particular, we first take a closer look at the striking differences between both samples that were combined for the study, and, secondly, we provide an in-depth discussion of their findings in relation to existing neurobehavioral models.

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.
