“…These are the ventral (vestibular), intermediate (lateral line) and dorsal longitudinal columns (electrosensory), respectively (Fig. 2) [Wullimann and Grothe 2014]. Depending on the number of placodes (see above), two ( Sarcopterygians ), three ( Myxoids and Petromyzontids ) or four ( Chondrichthyes and ray-finned fish) separate nerves innervate the lateral line neuromasts, of which only the posterior lateral line nerve innervates neuromasts on the trunk.…”

Detection of motion is a feature essential to any living animal. In vertebrates, mechanosensory hair cells organized into the lateral line and vestibular systems are used to detect external water or head/body motion, respectively. While the neuronal components to detect these physical attributes are similar between the two sensory systems, the organizational pattern of the receptors in the periphery and the distribution of hindbrain afferent and efferent projections are adapted to the specific functions of the respective system. Here we provide a concise review comparing the functional organization of the vestibular and lateral line systems from the development of the organs to the wiring from the periphery and the first processing stages. The goal of this review is to highlight the similarities and differences to demonstrate how evolution caused a common neuronal substrate to adapt to different functions, one for the detection of external water stimuli and the generation of sensory maps and the other for the detection of self-motion and the generation of motor commands for immediate behavioral reactions.

“…The effective stimulus differs between superficial and canal neuromasts because of their morphology and location (Chagnaud and Coombs, 2014); while superficial neuromasts primarily detect velocity, fluid dynamics within the canals means that flow inside the canal is proportional to the acceleration differences between the fish and surrounding water, which are detected by canal neuromasts. Information about the velocity and acceleration components of nearby water movements are then conducted by lateral line nerves to the brain, where they are ultimately integrated with other neural circuits to produce appropriate behavioral responses (Bleckmann and Mogdans, 2014;Wullimann and Grothe, 2014).…”

“…Several nuclei of the SDMN receive input from mechanosensory-processing regions ( Fig. 3; reviewed in Wullimann and Grothe, 2014), indicating that hydrodynamic information has the potential to affect social decisions. To date, only a single study has examined the role of mechanosensory signals in mediating activation of decision-making circuits in the brain .…”

“…To date, only a single study has examined the role of mechanosensory signals in mediating activation of decision-making circuits in the brain . Several studies have used neurophysiological and tract-tracing methods to elucidate where in the brain mechanosensory information is processed (reviewed in Bleckmann and Mogdans, 2014;Wullimann and Grothe, 2014), but these were performed on anesthetized, non-behaving animals while often using controlled artificial stimuli such as a vibrating sphere. In an alternative approach, we recently examined where in the brain socially relevant mechanosensory information is processed in awake, behaving animals, using lateral-line-intact and -ablated A. burtoni males .…”

Mechanosensory signaling as a potential mode of communication during social interactions in fishes

Signals produced during social interactions convey crucial information about the sender's identity, quality, reproductive state and social status. Fishes can detect near-body water movements via the mechanosensory lateral line system, and this sense is used during several common fish behaviors, such as schooling, rheotaxis and predator-prey interactions. In addition, many fish behaviors, such as aggressive lateral displays and reproductive body quivers, involve fin and body motions that generate water movements that can be detected by the lateral line system of nearby fish. This mechanosensory system is well studied for its role in obstacle avoidance and detection of inadvertent hydrodynamic cues generated during schooling and predator-prey interactions; however, little research has focused on the role of mechanosensory communication during social interactions. Here, we summarize the current literature on the use of mechanosensation-mediated behaviors during agonistic and reproductive encounters, as well as during parental care. Based on these studies, we hypothesize that mechanosensory signaling is an important but often overlooked mode of communication during conspecific social interactions in many fish species, and we highlight its importance during multimodal communication. Finally, we suggest potential avenues of future research that would allow us to better understand the role of mechanosensation in fish communication.

“…The first relay station for lateral line information processing is the medial octavolateralis nucleus (MON) of the medulla (e.g., Wullimann and Grothe 2014). Like primary lateral line afferents, many medullary lateral line units respond to bulk water flow (Kröther et al 2002) and to the water motions generated by a stationary vibrating sphere (Coombs et al 1998;Ali et al 2010).…”

Medullary lateral line units of rudd, Scardinius erythrophthalmus, are sensitive to Kármán vortex streets

We investigated the responses of medullary lateral line units of the rudd, Scardinius erythrophthalmus, to bulk water flow (7 cm s(-1)) and to water flow that contained vortices shed by an upstream half cylinder (diameter 1, 2, and 3 cm). Thirty-five percent of the medullary units either increased or decreased their discharge rate with the increasing cylinder diameter. In some units, the spike patterns revealed the vortex shedding frequency, i.e., in these units the amplitude of spike train frequency spectra was similar or identical to the vortex shedding frequency.
