| Topic: How do they know ...? | |
|---|---|
|
|
This has always been a curiosity of mine. How do doctors or scientists really know which parts of our brain are affected by certain stimuli? Or where our memory is really stored? Do they dissect people's brains and ask them where they feel it while prodding and poking around in there? Don't laugh, or roll your eyes, I'm serious! What about you? Anything you've ever been curious to know? Don't be shy about posting your query here because somebody else might know the answer... |

That answers my question... of course... why didn't I think of that first... women have the innate ability to tell us where everything's at, and what's going on, and when...
|
|
|
|

|
|
|
Actually, yeah, they do...
There have been studies done where the patient is under local anesthesia and doctors take thin probes and slowly stimulate each section of the brain and "map" out what sections control responses by asking questions and judging reactions. |

IDK... I don't like to be a doubting Thomas... but it doesn't make sense to me that sticking a probe to my brain and then asking me to recall a memory lets them know which part of my brain that memory is stored in.

They do it so in case there is a patient with a tumor in one part of the brain and they want to operate. They have to know if they are going to affect the speech center, the co-ordination center, destroy memory or other more vital ares by removing the tumor.

Oh, okay... now that makes sense...  thanks for clearing this query up for me...

No problem

they mapped the parts of the human brain decades ago---tools like a MTI ---there have been separate countless ongoing studies by different groups and people who come up with the same results plus info from hands work by doctors thats how they know so much,,

I'm going to say I thought I understood until I experienced certain things for myself.
I'm fluently bilingual in English and Spanish. Speak, read and write in both languages. I noticed a long time ago that when I'm tired toward the point of exhaustion, I lose my ability to speak Spanish, even though it's my native language. I don't drink often, much less get actually drunk. But in an occasion I did a few years back, I noticed the alcohol makes me lose my vocabulary in English. Scientists say your language abilities reside in some part of the brain. If that is so, wouldn't all language abilities reside in the same part? And wouldn't they all be affected equally when operating under impaired conditions? Or does it matter the conditions of the impairment? Just curious Oh. Now that you have me thinking, A third kind if impairment comes from migraines. Why when I have a migraine on th right side if my head does it seem like I have a higher tolerance for pain before the pain brings on nausea? Yet when it occurs on the left side it seems to hurt less but make me nauseated sooner? |

well that is an actual scan of my brain

My son was brain damaged at the age of 13 from a text driver.
I'm not going to get into this topic but let me just say they know. |

Well actually it's all falsifiable hypothesis, the very first rule of true science.
Most brain mapping was done between the late 19th and early 20th centuries, much of it France, most of it by studying the effects of brain trauma and the results of brain surgery. It is by inferrence. More recent medical research, in the last few years in Germany and Wales have found that in fact brain mapping is erroneous, that brain function is actually amorphous and not confined to specific regions, but happen upon specific regions by evolutionary convenience only as a likelihood. eg. one German patient in particular was born with only the right hemisphere of her brain, the left hemisphere left unformed and useless. In early childhood she had many troubles and experienced fits and siezures, however by her late teens her right hemisphere had adopted virtually all normal brain function that anybody has, and currently doctors describe her as a happy and intelligent young lady with a great sense of humour. Similarly severe brain trauma victims and post brain surgery outpatients with entire sections of their brains removed have subsequently recovered most or all healthy brain function as it simply moves somewhere else when the place it normally resides is lost. Again this is published in medical journals and directly challenges the neurological assertion of regional brain function. Where brain mapping came about however, was in the field of psychiatry, in modern times evolved as neurosciences, its role is largely in therapeutic treatment as opposed to surgical. Neurosurgery causes brain trauma to save a life, it's the therapists who have to try to work at rehabilitation following surgery. And brain mapping, whilst fallacious in the strictest biological sense, is an effective tool for them to use to help with that. Put simply, if your speech centre of the brain is cut out, assuming a healthy lifestyle and effective therapy, your brain will simply reinvent that same brain function somewhere else. |

Darn IT dodo! You're giving all my secrets away! 
Of course I don't mind scrubbing the toilet after I take the rock off my finger so it doesn't prevent me from reaching into the bowl...

Awesome self analysis, dreamer... you've sparked my curiosity even further with what you've discovered... seems there's much more to pinpointing exact brain function then pros know or are investigating yet. Or maybe they already have and a theory or paper has been advanced on the topics you question. |

My son was brain damaged at the age of 13 from a text driver. I'm not going to get into this topic but let me just say they know.  How unfortunate about your son. I hope he was able to recover satisfactorily as he matured?
Warm regards to you both.

Thank you, vanaheim... for this most telling history... this is astonishing news, but very welcome to help satiate my suspicions.

In some cases I have heard this to be true, but in the cases with massive stroke patients, it doesn't happen due to the damage.

A good deal of the knowledge comes from studying people who have had brain injury, strokes, etc.
For example, if the Broca's area of the brain is damaged, people have difficulty with speech and/or comprehension. So, we know that the Broca's area is necessary for speech |
