They're known for their timidity and love
of cheese, but scientists have tapped into the 'killer instinct' of
mice, to turn them into aggressive 'zombies'.
Researchers
isolated the brain circuitry in mice that coordinates predatory
hunting, including one set of neurons in the amygdala - the brain's
centre of emotion and motivation, making the animal pursue prey.
They
also 'switched on' another set in the brain region signalling the
animal to use its jaw and neck muscles to bite anything in its path – a
little like a fictional zombie.
