I've been musing about what happened to my son's brain this past semester. I came across an interesting theory based on what I know of other teens I've met.
1- The hormones kick in.
2- Depending on how hard, the brain is dissolved into mush
3- The brains leak out of the head
Now, depending on the teen, the second part can be more interesting. So far my son doesn't fit the theory, but I'm working on that. Either the teen recaptures his brains and uses a spiky hair gel which forces hair over the ears and retains the now liquified brains in the head, or they capture SOME of the brains and use it AS the gel that they spike their hair with. Depending on which approach they take, they may retain some semblance of sanity.
This explains my son's problem. He didn't recapture any of the liquified brains that I can tell. Thus, he has taken an almost complete leave of his senses. Hopefully we'll be able to find the puddle (likely under his bed) at some point in the near future and try out the spiky hair theory.
