Meet the insect that can shrink its brain — and then grow it back again

Posted by in category: neuroscience

Now THAT mechanism could be a game changer for functional, fully reversible cryonic suspension…


Indian jumping ants can shrink their brains by 20 per cent and then expand them back again to allow energy to be temporarily diverted towards egg production, according to a new study.

The inch-long arthropods were already known to be able to catch and kill prey twice their size, jump four inches in the air and compete in 40-day royal rumble death matches to decide the next queen of the colony.

Now new research shows that females prepare their bodies to lay eggs by releasing hormones that make their brains shrink by around 20 percent and cause their ovaries to balloon to five times their normal size.
