Music Memories Stored In Different Part of Brain Than Other Memories 94
An anonymous reader writes "Scientists have long believed that the ability to learn and appreciate music was stored in a different part of the brain than other types of memories. Now, researchers in Berlin think that they have concluded that theory. Dr. Christoph J. Ploner, Carson Finke, and Nazli Esfahani at the Department of Neurology at the Virchow campus in Berlin, Germany have examined a man who has lost all of his memories but has retained his ability to remember and learn songs."

I'd be curious to find out how psychological trauma affects music memory. Nothing fucks with memory worse than severe psychological trauma other than traumatic brain injuries). One of the reasons, as far as I understand, that psychological trauma affects memory is because adrenaline and cortisol are hormones used to form flashbulb memories. People who are traumatized often produce these hormones for longer durations and this damages the brain. If people who have psychologically caused memory loss can still form memories of music normally, that would imply that adrenaline and cortisol don't have an impact. It would also imply that music can't form flashbulb memories.
On a practical note, this might also imply that sound memories (like the sound of a gunshot or the words someone spoke in a violent confrontation) are less useful in court if they can't form flashbulb memories.

My grandfather has very advanced Alzheimers. He's been to the point for a while where he can't recognize family and doesn't have much to say about anything. However, in the 40's & 50's, he was a musician (played harmonica in a jazz-standards harmonica band). Through the 80's & 90's, he had a recording studio in his house and kept his music alive through multitracking himself. He definitely built his music into parts of his brain that haven't been ravaged by the disease.
Given a harmonica, he can bring back those songs, almost note-perfect.
I've also wondered if it's possible that music (or the ability to play) gets pushed into some sort of muscle memory rather than memory in the brain. As a musician myself, I know I can think about other things as I play things that are super-well-rehearsed. My fingers just somehow find the right notes.

Reminds me of Scott Adam's Spasmodic Dysphonia, and how he could not speak normally, but sing and speak in rhyme. http://www.outsidethebeltway.com/scott_adams_fixes_own_brain_can_now_speak/ [outsidethebeltway.com]
It's a different disease, but similar in the way that music is treated different by the brain.

I have always been able to memorize plays or poetry with almost effortless ease. In fact in my acting days at school I often knew pretty much all the words of all the parts (except for the acts/scenes that I was not involved in rehearsing) and I can still quote vast tracts of plays that I've not re-read for 20 years.
I also play the piano. Playing that from memory is a herculean effort with hours and hours of repetitive work required to get anything to stick. It also doesn't take very long for me to forget again unless I regularly play through something and I can get sudden blank moments when playing through something that I've played through dozens of times before without a problem. It's also not stress related as it happens regardless of whether I'm playing with someone else listening.

It's not "muscle memory", it's procedural memory, and it really comes from the brain! There's nothing magical about playing your tune and thinking of something else, without being conscious of what your fingers do. We all do lots of things without being conscious of every minute movement required.
Like walking to work. You don't have to vividly recall the way, you don't need to pay a constant, conscious attention to your surroundings. You just think about something else, and your feet and eyes (or walking stick if you're blind) relay the necessary information to your reptilian brain to run the procedure. You step out of your home and before you realize it, you're at your desk. Just as your fingers "somehow find the right notes", your legs somehow transport you to work.
Procedural memory is much more robust than "normal" memory. That's why Alzheimer's patients still know how to walk, take a shower, wipe their ass, do a triple jump, or dance the lambada. There's nothing surprising about them being able to play music, except for non-musicians or people who have tried learning an instrument, and who haven't got to the stage where what is learnt is pushed back in procedural memory.
Notice how sometimes, you make a mistake in your tune, and you can't remember for shit how the next part goes, unless you take it from the top ? That's the tell-tale sign your tune is in procedural memory : it's great because it allows you to think of something else, but it sucks when you make a mistake because procedural memory is "read" in sequences only. That's why it's good to rehearse your tunes by starting at an arbitrary point, so you have multiple points of entry to the same procedural sequence.
