Universidad de Zaragoza (orcid)0000-0002-5701-1670 Coupling of neurons favors the bursting behavior and the predominance of the tripod gait 2024 Access copy available to the general public Unrestricted In nature, it has been observed that the dominant locomotor pattern of hexapod insects is often the tripod gait. Our analysis of a Central Pattern Generator (CPG) of the insect movement gives reasons for this dominance: the mathematical CPG model presents the tripod pattern with bursting dynamics in a parametric region where an isolated neuron has a simpler behavior. That is, we show how the coupling of small networks of neurons makes the system to continue having bursting dynamics even when an isolated neuron would be spiking. Moreover, in parametric regions where a neuron shows chaotic dynamics, the CPG exhibits a chaotic synchronization phenomenon: the chaotic tripod gait. In other words, coupling loves bursting… and tripod gait. The hyperchaotic phenomenon is also present and we locate regions where up to four Lyapunov exponents are positive. info:eu-repo/grantAgreement/ES/AEI/PID2019-105674RB-I00 info:eu-repo/grantAgreement/ES/AEI/PID2021-122961NB-I00 info:eu-repo/grantAgreement/ES/DGA/E22-23R info:eu-repo/grantAgreement/ES/DGA/E24-23R info:eu-repo/grantAgreement/ES/DGA-FSE/E24-20R info:eu-repo/grantAgreement/ES/DGA/LMP 94-21 info:eu-repo/grantAgreement/ES/MICINN/PID2022-140556OB-I00 info:eu-repo/grantAgreement/EUR/MICINN/TED2021-130459B-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 5.6 2024 PHYSICS, MATHEMATICAL 1 / 61 = 0.016 2024 Q1 T1 MATHEMATICS, INTERDISCIPLINARY APPLICATIONS 7 / 136 = 0.051 2024 Q1 T1 PHYSICS, MULTIDISCIPLINARY 17 / 114 = 0.149 2024 Q1 T1 1.184 2024 Applied Mathematics 2024 Q1 Mathematical Physics 2024 Q1 Statistical and Nonlinear Physics 2024 Q1 Physics and Astronomy (miscellaneous) 2024 Q1 Mathematics (miscellaneous) 2024 Q1 9.9 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Barrio, R.
