Video 4. Animated reconstruction of a neuromast from a Notch-overexpression transgenic animal.
This neuromast from a Notch-overexpresion larva (N1) contains ten mature hair cells and one pair of immature hair cells along with eleven axonal terminals. Hair cells are colored according to their anteroposterior positions following rearrangement: more anterior hair cells in reddish shades and more posterior hair cells in blue. The terminals that form ribbon synapses with the former are delineated in various hues of orange and those associated with the latter are shaded green. The single efferent terminal is black. The spaces between the hair cells, and those around which the axonal terminals are arrayed, represent the positions of unseen supporting cells. In the second half of the sequence all the hair cells save one are removed to provide a view of the pattern of innervation, which is then further restricted to show the single dominant terminal. Occasional discontinuities in the terminals are an artifact of three-dimensional rendering rather than signifying an absence of data.
