I participated in a fMRI study last week and they gave me pictures of my brain. I thought I'd share. I did notice one cool congenital anomaly and I looked it up. It's called "cavum septum pellucidum". It's present in 10% or less of the population and it is benign. It's a splitting of the septum pellucidum into two parts. It can be caused by trauma. Looks like mom did drop me on my head...just kidding. The rest of the brain is just fine, though, as far as I could tell.
