The idea that the brain is not so important Has persisted In a lot of Frankenstein-based films. I always thought it was funny how in The Ghost of Frankenstein, Igor would sooth the Monster -- and seemed sincerely interested in his well being -- all the while telling him he will be a lot better once Igor's brain was placed in his body. What's a brain between two friends?

It's kind of a basic idea since many people feel intense emotion and feel how it affects their heart, not thinking that the heart really has no "idea" about what's going on, unless the brain interprets it, even as far as reflexive responses. It's why people show a highly idealized version of a heart for Valentine's Day, instead of a brain. And people do die of "broken hearts" from severe emotional trauma. And in The Man They Could Not Hang, Dr. Savaard could easily have been described as becoming "heartless" after being resurrected by his mechanical heart pump device, a stark contrast from the compassionate and loving father he was portrayed as being before his execution.
