Bypassing the visual cortex pathway for generating our fast automatic action!

How does the brain generate a fast automatic action?

Kim et al. find a subcortical loop circuit that generates habitual actions quickly. The posterior thalamus in the loop circuit stably retains reward value memories, even more than 200 days after learning. Historical values can be processed through this short subcortical circuit by bypassing the visual cortex, thus guiding fast automatic actions.

시상을 중심으로 한 fast action loop은 우리가 시각피질을 이용하여 물체가치 판단의 긴 여정을 하지 않고도, 그 물체에 대한 의사결정을 매우 효율적이고 신속하게 하도록 한다.
