Since little is known about how dopamine affects aversive learning in humans, Frick et al. recently sought to describe the role of dopamine in fear memory formation within the human amygdala, which we review in this blog post.
Storing aversive memories is important to survival, but learned avoidance responses decrease over time without reinforcement. Since little is known about the mechanisms behind this process, Bengoetxea de Tena et al. evaluated how naive rats respond to a learning and memory task under fear conditions in a recently published study, which we review in this blog post.
