Direction sensors

The image, which is reminiscent of an explosion of blue, is a cell structure typical of the extremities of neurons. This structure guides the growth of nerve cells in response to stimuli that indicate where their projections are required. In this case, the marks shows a protein that carries messenger RNA from the body of the neuron to its extremities, where the substances that account for growth are produced. The protein is shown in red where it is more abundant and in blue where it is scarcer.
