"However, sometimes even lone whales will make the social sounds, which would seem to cast doubt on the whole 'social interaction' theory."

Do you never talk to yourself while alone? Or just say something aloud that you know no one will hear? Doesn't sound that much different to me.

Good blog. Your writing might be enough to spare you when the machines assert their lordship.

This week's Science. Poor creationists- they miss the whole point

Humpback whales have "human" brain cells: study

Mon Nov 27, 1:42 PM ET

WASHINGTON (Reuters) - Humpback whales have a type of brain cell seen only in humans, the great apes, and other cetaceans such as dolphins, U.S. researchers reported on Monday.

This might mean such whales are more intelligent than they have been given credit for, and suggests the basis for complex brains either evolved more than once, or has gone unused by most species of animals, the researchers said.

The finding may help explain some of the behaviors seen in whales, such as intricate communication skills, the formation of alliances, cooperation, cultural transmission and tool usage, the researchers report in The Anatomical Record.

Patrick Hof and Estel Van der Gucht of the Department of Neuroscience at Mount Sinai School of Medicine in New York studied the brains of humpback whales and discovered a type of cell called a spindle neuron in the cortex, in areas comparable to where they are seen in humans and great apes.

Although the function of spindle neurons is not well understood, they may be involved in cognition -- learning, remembering and recognizing the world around oneself. Spindle cells may be affected by
Alzheimer's disease and other debilitating brain disorders such as autism and schizophrenia.

'COMPLEX SOCIAL PATTERNS'

The researches found spindle neurons in the same location in toothed whales with the largest brains, which the researchers said suggests that they may be related to brain size. Toothed whales such as orcas are generally considered more intelligent than baleen whales such as humpbacks and blue whales, which filter water for their food.

The humpbacks also had structures that resembled "islands" in the cerebral cortex, also seen in some other mammals.

These islands may have evolved in order to promote fast and efficient communication between neurons, the researchers said.

Spindle neurons probably first appeared in the common ancestor of hominids, humans and great apes about 15 million years ago, the researchers said -- they are not seen in lesser apes or monkeys.

In cetaceans they would have evolved earlier, possibly as early as 30 million years ago, the researchers said.

Either the spindle neurons were only kept in the animals with the largest brains or they evolved several times independently, the researchers said.

"In spite of the relative scarcity of information on many cetacean species, it is important to note in this context that sperm whales, killer whales, and certainly humpback whales, exhibit complex social patterns that included intricate communication skills, coalition-formation, cooperation, cultural transmission and tool usage," the researchers wrote.

"It is thus likely that some of these abilities are related to comparable histologic complexity in brain organization in cetaceans and in hominids."

"The mating songs are like a bellowing foghorn, with sound waves spreading far and wide in desperate hopes of catching a female's ear."

Wow, so these poor guys are out swimming alone, talking to themselves, bellowing out in sexually frustrated desparation.

So what do you have against whales?

msd

Absolutely nothing against whales, I just like to poke fun at those who would over-romanticize them. :)

Really fascinating post! I hope you had time to see some sea life in Hawaii. I've become very close with marine mammals here! Research on dolphins offers clues to the purpose of whale oil.

Wait a sec, Louise is in Hawaii? How did that not sink into my befuddled brain? Alas, I saw next to nothing of Hawaii, since when I wasn't attending sessions I was madly trying to keep abreast of my deadlines. I went for a couple of long walks in the sunshine, and did some of the work on my lovely balcony with ocean view... but that's about it.

Hi almost married Jen,
Awesome pic of the whale
so has the man been perfecting his 'foghorn' call?

Never mind the termites

Here's wishing you a mighty fine Sunday!

Dear Jennifer, You might have missed Clifford's blog devoted to Mark Fischer's wavelets + whale sounds work ==> http://asymptotia.com/2006/08/02/what-jonah-heard-but-did-not-see/
After many hours of discussions with Mark last October and November, what I want to know: Why are biologists not more interested in cetacean communication? Clearly cetaceans are intelligent, but how much? Today there is not a 'library' that maps cetaceans sounds to their behaviors. Why not? Wouldn't this be the first thing that any scientist would do? Now we have the perfect tools to begin to decipher their language (wavelets), and Mark is finding much more interest in his work from the art community rather than the scientific community.

Hi, I just read your post on how the accelerometer was used to pick up the low frequency sounds. That's really interesting and I am currently exploring infrasound in urban architecture/infrasound created by humans in urbanised areas. It's an interactive artwork that I am working on. Would it possible to get any form of schematics on the accelerometer and piezos and how it was used? That would be so helpful :) Thanks.
