Long description

This is a drawing of the same worm species from Figure 15, with numerous coloured dots marked throughout its body, particularly near its ends and upper and lower surfaces. These mark positions of neurons and muscles. Next to this is a highly interconnected web of coloured circles (nodes) and lines. The colours indicate the type of neuron: Sensory neuron in blue, Interneuron in orange and Motor neuron in yellow. Pink/purple circles are muscles. The size of the node is proportional to the number of its connections. (In this particular study, researchers were studying the response of the worm to gentle touch. The nodes of a few sensory neurons are triangular in shape indicating where the input touch was applied. Filled nodes indicate neurons that were previously known to be involved in the worm’s response.)
