生物体通常会在周围寻找更好的环境,更多的食物,或者躲避捕食者。通常,动物通过整合来自环境的感觉线索与它们的运动器官来做到这一点。对于具有运动性的单细胞或小生物体,由于其小尺寸而施加的基本物理限制导致了特定于微观世界的替代导航策略。有趣的是,这些无数的探索行为或感觉功能的基础是多尺度周期性活动的开始,例如纤毛和鞭毛的波动,毛细胞的振动,或迁移中性粒细胞的振荡形状模式。在这里,我探讨振荡动力学基础微真核生物和假设,这些积极的振荡发挥了关键作用,提高保真度的自适应感觉运动整合。
Living organisms routinely navigate their surroundings in search of better conditions, more food, or to avoid predators. Typically, animals do so by integrating sensory cues from the environment with their locomotor apparatuses. For single cells or small organisms that possess motility, fundamental physical constraints imposed by their small size have led to alternative navigation strategies that are specific to the microscopic world. Intriguingly, underlying these myriad exploratory behaviours or sensory functions is the onset of periodic activity at multiple scales, such as the undulations of cilia and flagella, the vibrations of hair cells, or the oscillatory shape modes of migrating neutrophils. Here, I explore oscillatory dynamics in basal microeukaryotes and hypothesize that these active oscillations play a critical role in enhancing the fidelity of adaptive sensorimotor integration.
