Two effects working here: - The recall effect when you see the same areas again. [0] - The effect of running itself. Your ARAS (or Ascending RAS, or Ascending Reticular Activating System -- not everyone uses the same acronym) in your brainstem is hurling a whole lot of neurotransmitters (like adrenaline and dopamine) towards your hippocampus. Long story short: you'll be able to remember better for the next 30 to 60 minutes. [1] [0] Too lazy to look up the source (sorry, not having my day in terms of productivity), anyone who studied psychology would've learned the study about people diving under water and doing a memory task and then having a much better recall underwater then on land regarding that memory task. [1] Source: learned it at the Vrije Universiteit Amsterdam from Prof. Dr. Erik Scherder. I still don't know where a paper is that describes the full story. I also couldn't find too much information about it online, and I never had enough time to fully figure the story out. So if there's a neuroscientist in the room, please help me out :D
