See Benedict's Carey's article on Henry Molaison — known during his lifetime only as H.M., to protect his privacy — who lost the ability to form new memories after a brain operation in 1953, and over the next half century became the most studied patient in brain science. Here is the dissection in progress:
We have reached the corpus callosum. The team is resting for the night. The brain will be safe surrounded by our chillers until tomorrow morning. The cutting will resume again at 8AM PST.
Tomorrow will be a big day - We will try to cover the medial temporal lobes and the area surrounding the hippocampus.
