You see an obstacle in the middle of the road while driving and have to decide whether to swerve to the left or to the right. There is little time, and you have to integrate perceptual information (visual, auditory, tactile, proprioceptive, …), memory (previous experience, condition of car and road, …), and so on. The complex and parallel interactions of neural information from these sources then boil down into a quick, resolute action. This is the process of decision-making.
