Amnesia effects, outcomes, ectt..?

depends on what part of the brain is affected. for example, going through the space/time continuum, will it affect his motor skills? then maybe he would forget how to grab things. He would recognize them, but be unable to know how to work them. Or perhaps it affect the visual part of the brain, the back side of your brain, he wouldn't be able to recognize anything visual, but somehow would know how to function with his motor skills. This is what will make it interesting. How does he know this person? He doesn't visually recognize her, but her voice is so familiar..... I added a site with the map of the brain. Maybe it will stimulate some ideas/
