It’s fascinating to me the effect food has on the brain, but also the effect that our brain can have on deciding which foods we choose to eat. Do you ever wonder why you get mean or agitated when you’re hungry? Or why do you search for snacks when you’re stressed, or even don’t eat at all? We tackle hypotheses related to this in the lab every day using mouse models! If we can start to uncover how the brain both directs and responds to our food environments, we can better understand behavior, but potentially also ask new questions about the connection of our energy state, i.e. how hungry we are, to brain function. ‘You are what you eat’ is a saying, and we are trying to understand how the brain, and the food we eat, interact to make this happen.
