Protecting Sight #240: What happens when you remove the hippocampus? Horizontal chop technique & junctional epidermolysis bullosa (JEB). The science of well-being.

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, podcast, or significant work.

Here is today’s list:

1. Ted Talk – Sam Kean: What happens when you remove the hippocampus?“When Henry Molaison (now widely known as H.M.) cracked his skull in an accident, he began blacking out and having seizures. In an attempt to cure him, daredevil surgeon Dr. William Skoville removed H.M.’s hippocampus. Luckily, the seizures did go away — but so did his long-term memory! Sam Kean walks us through this astonishing medical case, detailing everything H.M. taught us about the brain and memory. [Directed by Anton Bogaty, narrated by Addison Anderson].” (

2. Cataract Surgery – Uday Devgan MD – CataractCoach 1008: Horizontal Chop Technique. Excellent technique.
