...) by deflection in the same direction, depending on the sign of ctenophore geotaxis (positive or negative). The beat frequency of many cilia is controlled by concentrations of Ca 2+ , membrane potential and neural input. How these factors affect deflection-induced ciliary beating in balancers was investigated...

...T. Fenchel; B. J. Finlay ABSTRACT Geotaxis is demonstrated in the ciliated protozoon Loxodes . This behaviour is mediated by a mechanoreceptor which is probably the Müller body, an organelle characteristic of loxodid ciliates. The geotactic response is sensitive to dissolved oxygen tension...
