Robust undulatory locomotion through neuromechanical adjustments in a dissipative medium

Journal of The Royal Society Interface, Год журнала: 2025, Номер 22(222)

Dissipative environments are ubiquitous in nature, from microscopic swimmers low-Reynolds-number fluids to macroscopic animals frictional media. In this study, we consider a mathematical model of slender elastic locomotor with an internal rhythmic neural pattern generator examine various undulatory locomotion such as Caenorhabditis elegans swimming and crawling behaviours. By using local mechanical load mechanosensory feedback, have found that robustly emerges different rheological This progressive behaviour is then characterized global attractor through dynamical systems analysis Poincaré section. Furthermore, by controlling the mechanosensation, were able design manoeuvre progressive, reverse turning motions well apparently random, complex behaviours, reminiscent those experimentally observed C. elegans. The mechanisms together our methodology, useful for deciphering animal adaptive behaviours designing robots capable wide range dissipative environments.

Computational fluid–structure interaction in biology and soft robots: A review

Physics of Fluids, Год журнала: 2024, Номер 36(10)

Опубликована: Окт. 1, 2024

The omnipresence of fluid–structure interaction (FSI) in biological systems is indisputable—from the vibration leaves to locomotion fish, flying birds, and cardiovascular biomechanics; FSI indeed ubiquitous. Even stimuli-responsive soft robots that typically operate inside a fluid medium, these physical interactions are prevalent. Therefore, it becomes mandatory have thorough understanding their fully coupled physics involving strong two-way between solid domains. Although state-of-the-art computational frameworks robust numerical techniques been developed study complex mechanisms associated nonlinearities multiple spatiotemporal scales, we believe timely review current development, emerging techniques, future challenges would further stimulate research along this direction. explore broad landscape myriad avenues herald emphasizing manifold occurrences biology advanced robotic technologies, while underlining plethora adopted fundamental phenomena.

Harnessing spinal circuit reorganization for targeted functional recovery after spinal cord injury

Neurobiology of Disease, Год журнала: 2025, Номер unknown, С. 106854 - 106854

Опубликована: Фев. 1, 2025

Spinal cord injury (SCI) disrupts the communication between brain and spinal cord, resulting in loss of motor function below site. However, spontaneous structural functional plasticity occurs neural circuits after SCI, with unaffected synaptic inputs forming new connections detour pathways to support recovery. The review discusses various mechanisms circuit reorganization post-SCI, including supraspinal pathways, interneurons, central pattern generators. Functional recovery may rely on maintaining a balance excitatory inhibitory activity, as well enhancing proprioceptive input, which plays key role limb stability. emphasizes importance endogenous neuronal regeneration, neuromodulation therapies (such electrical stimulation) proprioception SCI treatment. Future research should integrate advanced technologies such gene targeting, imaging, single-cell mapping better understand underpinning recovery, aiming identify subpopulations for targeted reconstruction enhanced By harnessing reorganization, these efforts hold potential pave way more precise effective strategies SCI.
