What Does The Cerebrum Do ?
« on: 06/10/2008 13:31:20 »
Dear Cerebrumologists, experts in brains and people who have them !

As a sheepy, I am course fortunate to be in possession of my very own brain !

Look..here it is *flips boot lid, latch open , scoops brain out*



Now that's a quality brain is it not ?..as far as brains go..it's a looker !..it's mine..all mine  *morose unhinged laughter*..mwahahawwwhahaaaaw !!


But large parts of my cerebral cortex are ' silent areas', that is to say, they give neither sensation nor movement when stimulated by an electric current. I can chop em out and still live. I would not become demented (well more than I already am :)). My personality might change though, but, providing the motor sensory areas are left intact, it is amazing what large amounts of the cerebral cortex can be sacrificed without any marked changes taking place in behaviour.

Has our massive cerebrum become too large ? a sort of overgrown fungus which is merely filling up space in my head ? Or do I have more brain than i know what to do with ? It is generally understood that  we utilize just a fraction of our available brainpower yes ?...so is it that the cerebral cortex wields powers and potentials that we have just not developed ?

We reach the end of our lives with a brain only partly utilized...the other organs fail but the cerebrum is still youthful

Why's that then ?


whajafink ?

Hugs & Shmishs

It is a widely believed myth that we only use a fraction of out brain.
If this were true JFK would have had a longer career  :)

We could have become too intelligent for our own good,
 e.g. the invention of atomic/biological weapons, or internal combustion engine, (causing anthropogenic global warming),
 could cause our extinction.

At least 5% of those over 85 have dementia.

Dear Cerebrumologists, experts in brains

A British neurologist who wrote textbooks on the subject was called "Walter Brain", i.e. Dr Brain the brain doctor.

(His books should have been entitled "Walter on the brain:) )

Thank ewe Mr RD.....but this does not explain the relevant redundancy of the cerebellum.

People may grow old with dementia (and as you say it's only 5%...quite small).....this means that 95% do not have dementia.

It's the cerebellum that I am particularly interested in , in this case...it's takes up what seems to be a lot of space !!...for what appears to be little brain power !!...that's expensive scaffolding !!..or perhaps padding ? ;)

I was always under the impression that it kicked in when other more active areas of the brain were permanently injured and people are able that area of the brain to relearn the things the other portion can no longer hold and kind of start over using unused areas of the cerebellum. Am I mistaken in this...???

if the discussion relates to what the cerebrum is all about i have little to add here. if it relates to the cerebellum, i would say that it functions as a sub-system to the cerebrum in that it allows for the greater precision in all motor functions (which include such higher motor functions as talking so it is not excluded from higher intellectual functions). in animals such as birds one sees that nearly the entire brain is cerebellar-like for they function mostly motorically.
