    In the transgenic mice used by Dr Rebecca Campbell’s team, GnRH neurons in the brain give off a green fluorescent glow. The yellow/red-coloured neuron has also been filled with neurobiotin (which glows red) to show how long its dendrites are.

    The length of the dendrites is unusual – more than 2 mm, so the cells are 100 times longer than they are wide! Knowing this has helped Rebecca solve a puzzle on how GnRH neurons make connections in the brain.
