FIG. 10. Ontogeny of neuromast distribution in E. lori derived from fluorescent images. (A) 0 dph, 3 mm TL; (B) 10 dph, 4.5 mm SL; (C) 20 dph, 6.5 mm SL; (D) 31 dph, 9 mm SL; and (E) 38 dph, 9 mm SL presettlement larva. Pectoral fin removed to facilitate visualization of all neuromasts on the trunk. Yolk sac not drawn. Scale bar ¼ 1 mm. See Figures 3 and 4 for identity of neuromasts.

FIG. 2. Neuromast distributions in E. lori vitally stained with 4-di-2-ASP (lateral view, rostral to the left). (A) 0 dph (3 mm NL; yolk sac larva, fin folds still present) with only nine neuromasts present on head. By 1 dph, the yolk sac is fully absorbed and by 10 dph, flexion has started. (B) 38 dph (9.5 mm SL, pre-settlement) individual with all neuromast lines present on head; only the neuromasts in lines on operculum and mandible have begun to proliferate. Canal neuromasts are still visible (e.g., dorsal to orbit), indicating that the canals are not yet fully ossified. Settlement occurs at ~30–45 dph, 9–11 mm SL. (C) Wild-caught adult (42 mm SL) with lines of proliferated superficial neuromasts on head. (D) Trunk and tail of 20 dph (6 mm SL) larva. The few neuromasts on trunk will proliferate to become short vertical series of superficial neuromasts (see F). A few neuromasts on the caudal fin occur in three lines. (E) Anterior portion of the trunk (adult, 42 mm SL) illustrating several short lines of neuromasts. (F) Posterior portion of the trunk (adult, 42 mm SL) with well-organized vertical lines of neuromasts (''stitches'') on each myomere along horizontal septum. (G) Caudal fin (adult, 42 mm SL) with three lines (lines lc, lc1, and lc2) of densely placed neuromasts extending from the fin base to the tip of the caudal fin on the membranes between fin rays. Caudal-fin membranes are so thin that the neuromasts from both the left (white arrowhead) and right (yellow arrowhead) side are visible within a line. See Figures 3 and 4 for identification of neuromast lines.

Nuclei of cells in two layers are visible in the neuromast (upper layer, sensory hair cells; lower layer, non-sensory support cells). (C) Left and right CNs (arrows) in the SO canal in the dorsal midline, with canal walls rising (*, Stage IIb), but not yet enclosing the CNs. (D) Left and right CNs (arrows, as in C; cupula of left neuromast is visible) are enclosed in the ossified SO canal (Stage IV; wild-caught settler, 14 mm SL). (E) Example of a line of densely placed superficial neuromasts (line c2) in wild-caught settler (14 mm SL) in the nasal area; prominent olfactory epithelium (oe). Stages of canal development (I–IV) follow Webb and Shirey (2003). (F–J) Ontogeny of superficial neuromast size and shape in E. lori showing diamond shape and gradual restriction of hair cells to a central, oval sensory strip. Axis of best physiological sensitivity (hair cell orientation) is perpendicular to the long axis of the neuromast. (F) 0 dph—neuromast on trunk is already diamond-shaped, (G) 10 dph—neuromast on trunk, (H) 20 dph—neuromast on cheek, (I) 34 dph—neuromast on cheek, note that sensory strip takes up a smaller portion of area of the neuromast compared to those in F–H. (J) Adult—superficial neuromast on caudal fin. Scale bars: A–E, 50 lm; F–H, 2 lm; I–J, 5 lm.

A practical method for estimating coupling functions in complex dynamical systems
<p>A foremost challenge in modern network science is the inverse problem of reconstruction (inference) of coupling equations and network topology from the measurements of the network's dynamics. Of particular interest are the methods that can operate on real (empirical) data without interfering with the system. One of such earlier attempts (Tokuda et al. 2007 Phys. Rev. Lett. 99, 064101) was a method suited for general limit-cycle oscillators, yielding both oscillators' natural frequencies and coupling functions between them (phase equations) from empirically measured time series. The present paper reviews the above method in a way comprehensive to domain-scientists other than physics. It also presents applications of the method to (i) detection of the network connectivity, (ii) inference of the phase sensitivity function, (iii) approximation of the interaction among phase-coherent chaotic oscillators, and (iv) experimental data from a forced Van der Pol electric circuit. This reaffirms the range of applicability of the method for reconstructing coupling functions and makes it accessible to a much wider scientific community.</p>
