Boycott copied his technique from neurosurgeon Wilder Penfield, who treated epilepsy patients by burning out the misbehaving bits of their brains.

You know, just to see what would happen. A zap in one spot above the ears caused a tingle in the left hand. In another spot, tingles in the leg. And so Penfield discovered that the sensory cortex is a homunculus, with specific brain areas mapping onto different parts of your body. Over time, scientists tried the electrical stimulation technique on all kinds of animalsincluding Boycott's cuttlefish.

Chiao tried out the same thing in a related cephalopod, the oval squidbut he took it to the next level. In a paper published in the Journal of Neuroscience in January, he describes putting electrodes in a bunch of different parts of the optic lobe, stimulating them, and recording the resulting body patterns.

March 23, Stanford researcher investigates how squid communicate in the dark Researchers begin to reveal how social squid communicate in the near-blackness of the deep sea.

Such antagonistic displays may be particularly important for Humboldt squid because these animals are highly cannibalistic. As Burford explained. When we hook a Humboldt squid on a fishing line and try to reel it in, sometimes the other squids will start to eat it, following it all the way to surface.

In addition, the scientists noted that the squids sometimes use patterns in specific sequences, similar to how humans arrange words in a sentence. Though the meaning of the signals remains unknown, this work suggests that Humboldt squids use changes in body patterns as a consistent and effective means of communication.

This finding contradicts a lingering paradigm in marine biology that behavioral signals are uncommon in the deep sea because of lack of light. Based on near-surface night-time observations and squid dissections, the authors believe that Humboldt squid can make their entire bodies glow with a yellow-green bioluminescence. Unlike most other glowing animals, however, the glowing organs photophores in Humboldt squid are located underneath their skin. A group of Humboldt squid swim in formation about meters feet below the surface of Monterey Bay.
