from what i hear and the info i gather, deer are very smart animals. they may return after being spooked because they are naturally curious. but they won't come back unless they feel safe. if they're memmory only last 7 mins then how do they follow the same trails, or the same scrape line from year to year. i think your info is wrong tho i have never studied a the brain of a deer or anything like that
