Heterogeneity in cilia patterning enables multiple flow functions in Paramecium

Daphne M. Laan, Aikaterini Maria Kourkoulou, Guillermina R. Ramirez-San Juan

Paramecium tetraurelia partitions its ciliary array into a dense, fast-beating domain anterior to the oral apparatus that drives feeding flows and a sparser, slower domain that drives swimming.

Metachronal wave coordination encodes multimodal swimming in ciliated unicellular predators

Aikaterini Maria Kourkoulou, Maggie Liu, Arnold J. T. M. Mathijssen, Guillermina R. Ramirez-San Juan

This study shows how metachronal wave coordination in Didinium nasutum enables diverse swimming behaviors by regulating propulsion and maneuverability through dynamic ciliary patterns.
