Scientists Find 'Altruistic' Center of the Brain

davidwr writes "A team of researchers at Duke University published a paper linking the brain's posterior superior temporal cortex to altruistic behavior. The BBC also picked up the story. If confirmed this has applications in neurology, psychology, child-rearing, and a host of other domains. From the BBC piece: 'Using brain scans, the US investigators found this region related to a person's real-life unselfish behaviour. The Duke University Medical Center study on 45 volunteers is published in Nature Neuroscience. The participants were asked to disclose how often they engaged in different helping behaviours, such as doing charity work, and were also asked to play a computer game designed to measure altruism.'"

    I'm sick of being altruistic while selfish bastards get all the money.

      Better yet- this could be the key to a new version of communism. Only those with well-developed altruistic brains need apply to be Alphas or Betas in our brave, new world.

    This just seems like a very roundabout, tenuous way to find the altruism center. They used an extremely unreliable method -- survey responses -- and then had people play a computer game they *know* is pretend, which would just show how altruistic they are in fake scenarios, which isn't really altruism, just like my willingness to slaughter demons in Doom doesn't show a real "willingness to resort to violence".

    Much cheaper way to accomplish the same thing:

    -Scan Ayn Rand's brain (Peikoff would be a fine subsititute today if you need a living one).
    -Compare to an average human's brain.
    -Look for the most striking difference.

      I'm being evaluated for a medial temporal lobectomy for epileptic seizures.

      I'll let you guys know if I wake up after the surgery to find that I'm altruistic on my left side only. Or maybe I won't care about keeping you informed anymore; I figure it's 50-50.

      Man I wish I knew someone who was having brain surgery. It would be so much fun to speak gibberish to them when they wake up, and then when they start screaming just say, "aww man don't worry I am just messing with you". Yeah I just know they would love that.

      The whole claim is built on a suspect modularist model, by which one finds a "center" for everything. High-level behaviors may correspond with certain activations in certain regions in neuro-typical people, but that's by no means the same thing as finding an "x" center, either. It could be that what is being activated is responsible for something far simpler - such as facial recognition, or even the production of affect - but that the altruistic behavior per se is considerably more distributed. The remarkable plasticity of brain function suggests that this search for "x" centers is fraught with problems.

      I've had no working sense of humor for days at a time. This isn't one of those times though. But I've regained consciousness surrounded by unhelpful people before, so cracks like that bring back sore memories for me. The worst is when people (esp. cops) think I'm on drugs. I wake up with 1% of my brain working and retrograde amnesia and a migraine with nausea and right away people are giving me bullshit about drugs.

    You need to brush up on your Ayn Rand. The term "altruist" is used as a derogatory term, and "voluntary altruism" is something to be reviled and weakness.

    "Nobody respects an altruist, neither in private life nor in international affairs. An altruist is a person who keeps sacrificing himself and his values, which means: sacrificing his friends to his enemies, his allies to his protagonists, his interests to any cry for help, his strength to anyone's weakness, his convictions to anyone's wishes, the truth to any lie, the good to any evil."

    "It stands to reason that where there's sacrifice, there's someone collecting sacrificial offerings. Where there's service, there's someone being served. The man who speaks to you of sacrifice, speaks of slaves and masters. And intends to be the master."

    "Just as life is an end in itself, so every living human being is an end in himself, not the means to the ends or the welfare of others - and, therefore, man must live for his own sake, neither sacrificing himself to others nor sacrificing others to himself."

    To that end, I suggest Ayn Rand was a self-serving bitch.

    While it is true that we are born selfish...

    What on Earth does this mean?

    We are social primates, and therefore have evolved a variety of reciprocal-aid mechanisms in our behaviour. We are more likely to show helping behaviour toward our closer kin, but because we also (as a species) practice exogamy (breeding outside our kin group) rather vigorously we have a tendency to show helping behaviour toward anyone or anything that even looks remotely like us.

    When raised in sufficiently violent, unloving circumstances that tendency may never be developed, but contra Freud it is not repression of our nature that makes us humane (anymore than feral, asocialized humans behave humanely) but rather a nurturing, loving and secure upbringing.

    Firstly, 45 is not enough for a statistical analysis involving brain scans, there is enough multiplicity as it is, there was bound to be *some* congruence. Seriously, they are making predictions from 45 people?!?!
    IAAFR (I am an fMRI researcher) and I can say without reservation that this comment is blatantly incorrect. As with any statistical analsysis, you take into account the variability in the data when making statistical tests. You have some idea of what to expect based on chance alone, and you must exceed that by a tremendous amount. With fMRI we tend to be excessively conservative with statistics, since we do a statistical test at every voxel in the image acquired -- it takes very high levels of statistical parameters to be accepted as a significant result.

    45 subjects is actually a very large sample for an imaging study (fMRI is very expensive). Most studies use 12-16 people.

    As for the term "volunteers", anyone who participates in research in the U.S. is a volunteer. We cannot and should not force people to participate in research studies. The term volunteer does not mean they were not compensated for their time.
