BBC News: ‘Sarcasm’ brain areas discovered

‘Sarcasm’ brain areas discovered

The scientists pinpointed three important brain areas Scientists say they have located the parts of the brain that comprehend sarcasm - honestly.

By comparing healthy people and those with damage to different parts of the brain, they found the front of the brain was key to understanding sarcasm.

Damage to any of three different areas could render individuals unable to understand sarcastic comments.

Dr Shamay-Tsoory said this fitted with what is already known about the anatomy of the brain.

She said language areas on the left hand side of the brain interpret the literal meaning of words and the frontal lobes and the right side of the brain understand the social and emotional context.

An area called the right ventromedial prefrontal cortex then integrates the literal meaning with the social/emotional context, which will reveal any sarcasm.

“A lesion in each region in the network can impair sarcasm, because if someone has a problem understanding a social situation, he or she may fail to understand the literal language,” she said.

Dawn of Man

I hope some of you watched the Bowerbirds video, because it is really excellent. David Attenborough, the guy who made the documentary, is one of the most awesome people in the world, and that special is one of his best nature films.

I’ve been out of commission for the last few weeks with some personal issues, so I haven’t been able to do anything with this site. However, now I’m putting together my college class, and I’ll be compiling some more videos to show them. I’ll try to post anything interesting here too, but if I forget you can follow along on the course website or my own site.

Anyway, I wanted to show you guys 2001: A Space Odyssey in class but couldn’t find it at Blockbuster. Luckily, YouTube comes through.

Spore

Spore is the new game by the creator of Sim City. And its freaking awesome.  If you haven’t watched it yet, you should. Its worth it, believe me. And you have to watch it all the way to the end.

Still Having Difficulty With The Clark vs. Descartes Problem?

I was recently surfing the web- marveling at how vast and unorganized the internet really is… when I came across an undelivered speech prepared for a conference on Science & Literature in 1991 in Montreal. It happened to be about the nature of the mind and intelligence. In short: a fascinating read. Thought I’d post it! Have fun!

“Human nature and technology”

We are unknown to ourselves… and with good reason. We have never sought ourselves — how could it happen that we should ever find ourselves? … Whatever else there is in life, so-called ‘experiences’– which of us has sufficient earnestness for them? Or sufficient time? Present experience has, I am afraid, always found us ‘absent-minded’: we cannot give our hearts to it– not even our ears! rather, as one divinely preoccupied and immersed in himself into whose ear the bell has just boomed with all its strength the twelve beats of noon suddenly starts up and asks himself: ‘what really was that which just struck?’ so we sometimes rub our ears afterward and ask, utterly surprised and disconcerted, ‘what really was that which we have just experienced?’ and moreover: ‘who are we really?’

On the Genealogy of Morals, preface, Nietzsche

Notice the title of this post is in quotes. Remember what that means?

One of the most common criticisms on the evaluations was that the course title and description did not accurately reflect the course content. I admit that I was not as strong on the ‘human nature’ aspect as I was on the ‘technology’ side. But I think I can defend my approach.

Almost everyone we read agrees that a discussion of human nature cannot discount the effects of technology on our social and individual lives. I went into the course with the strong bias that the title of the course was entirely redundant- there is no discussion of human nature without discussing technology, and there is no discussion of technology without a treatment of human nature.

But as the Nietzsche quote above suggests, the two discussion are not just mutually reinforcing. Both bear a strong parallel, emphasized later by Heidegger and Jonas, not to mention Gibson: in neither case do we understand what is going on. We can’t explain our own selves any better than we can explain our technology. We lose ourselves, including our technology, in the process of living our lives. Not until later can we stop and ask the question “who are we?” and “what are these machines that are so important to our lives?”

Gehlen suggests that the inorganic is fundamentally more knowable than the organic. This may be questionable epistemology, but it implies that the technology that surrounds us is easier to discuss than our own nature. We saw during our own brainstorming session at the beginning of class that our opinions on technology were much less articulate than our understanding of human nature; and yet, our discussion of human nature was often confused, overly general, and served to simply reaffirm our received biases. By the end of the class, we were talking much more intelligently about technology, and everyone claimed to have a hightened sense of awareness of the affects of technology on their own lives.

I’d like to think that this process entailed not only a deeper understanding of technology, but also a deeper understanding of your nature as a human being. Since we never had the opportunity to close that chapter of the discussion, I’d like you guys to use this post to respond to the following question: How has your understanding of human nature changed since you’ve taken this class?

Ampulex compressa

As an adult, Ampulex compressa seems like your normal wasp, buzzing about and mating. But things get weird when it’s time for a female to lay an egg. She finds a cockroach to make her egg’s host, and proceeds to deliver two precise stings. The first she delivers to the roach’s mid-section, causing its front legs buckle. The brief paralysis caused by the first sting gives the wasp the luxury of time to deliver a more precise sting to the head.

The wasp slips her stinger through the roach’s exoskeleton and directly into its brain. She apparently use ssensors along the sides of the stinger to guide it through the brain, a bit like a surgeon snaking his way to an appendix with a laparoscope. She continues to probe the roach’s brain until she reaches one particular spot that appears to control the escape reflex. She injects a second venom that influences these neurons in such a way that the escape reflex disappears.

From the outside, the effect is surreal. The wasp does not paralyze the cockroach. In fact, the roach is able to lift up its front legs again and walk. But now it cannot move of its own accord. The wasp takes hold of one of the roach’s antennae and leads it–in the words of Israeli scientists who study Ampulex–like a dog on a leash.

The zombie roach crawls where its master leads, which turns out to be the wasp’s burrow. The roach creeps obediently into the burrow and sits there quietly, while the wasp plugs up the burrow with pebbles. Now the wasp turns to the roach once more and lays an egg on its underside. The roach does not resist. The egg hatches, and the larva chews a hole in the side of the roach. In it goes.

The larva grows inside the roach, devouring the organs of its host, for about eight days. It is then ready to weave itself a cocoon–which it makes within the roach as well. After four more weeks, the wasp grows to an adult. It breaks out of its cocoon, and out of the roach as well. Seeing a full-grown wasp crawl out of a roach suddenly makes those Alien movies look pretty derivative. |The Wisdom of Parasites|
