Negative experiences can be rewired in the brain, although it may be more challenging than forming them.

“You can wire things in one direction, and if you don't like it, or if your parents don't like it, you can wire it back in another direction. Although, as we both know, there's a little bit of an asymmetry to that. It's kind of easier to get negative experiences wired into the brain, and a little bit harder, or a lot harder as the case may be, to undo those.”
