Sodium and dead squid
 

http://video.dailytelegraph.com.au/2.../Dancing-squid

The squid is dead "Richard Fan shot the above video on a visit to Hokkaido’s Ikkatei Tabiji restaurant and explains that sodium in the soy causes neurons to fire, making the muscles twitch."

I didnt know salt was this powerful. Should we be cutting out salt based on this vid? P/N damaged neurons may fire on hi sodium diet

I think it is the monosodium glutamate in the soy sauce.

There are channels in nerve cells called sodium ion channels.
Some drugs block these, and hence are used in PN.
Lidocaine is one.

That is a totally creepy video, but fascinating too. I'm sending it to my son. He'll love it.

It reminds me of a Korean restaurant my son took me to. I ordered some Japanese noodle dish that came with fish flakes on it all over. The whole thing was waving and moving, and I said-- OMG this is ALIVE??! Within seconds EVERYONE was looking at us and a manager appeared and thus followed the explanations! I could never do a squid like this one in the video.
Although I don't mind them cooked up in other ways...LOL

I bet that squid has to be pretty fresh to react like that.
