  In this work, we aim to devise an end-to-end spiking implementation for
contour tracking in 3D media inspired by chemotaxis, where the worm reaches the
region which has the given set concentration. For a planer medium, efficient
contour tracking algorithms have already been devised, but a new degree of
freedom has quite a few challenges. Here we devise an algorithm based on
klinokinesis - where the motion of the worm is in response to the stimuli but
not proportional to it. Thus the path followed is not the shortest, but we can
track the set concentration successfully. We are using simple LIF neurons for
the neural network implementation, considering the feasibility of its
implementation in the neuromorphic computing hardware.
