a, Mean firing rate for a right hippocampal cell that responded when seeking passengers (P) and b, for a different right hippocampal cell that responded when seeking SA. c, Goal-responsive cells were not significantly clustered by anatomical region. Some goal-responsive cells modulated their firing rate based on what was being viewed, such as this cell in the right amygdala (d), which responded preferentially when the goal (shop SB) was in view. This panel shows firing rates for all combinations of shop being viewed and shop being sought; view 
goal conjunctive cells were not clustered by anatomical region.
