Is There a Difference Between the Left and Right Hemisphere?

Some people like to talk about it in terms of functions. Like, why do we have two hemispheres that are wired differently? Because sometimes our brain needs to accomplish two jobs that would compete with one another if they were happening in an overlapping way. And so that interpretation piece, some argue, is about predicting the future. Whereas the right hemisphere is focused on processing the here and now. So you need all of the data. You know, you need the whole picture to understand if there's a tiger coming at you,. even if there's nothing in your previous experience to suggest that there could be a tiger.
