SUMMARY The ciliated protozoan Paramecium spontaneously changes its swimming direction in the absence of external stimuli. Such behavior is based on resting potential fluctuations, the amplitudes of which reach a few mV. When the resting potential fluctuation is positive and large, a spike-like depolarization is frequently elicited that reverses the beating of the cilia associated with directional changes during swimming. We aimed to study how the resting potential fluctuation is amplified…

Mechanism regulating Ca2+-dependent mechanosensory behaviour in sea urchin spermatozoa.
TLDR
The results show that the Ca(2+)-dependent mechanosensory behaviour of the sea urchin sperm is regulated by organized functioning of the membrane environment including the plasma membrane proteins and flagellasialin.
Excitation of Paramecium with Membrane Potential Generation for Swimming Direction by Cilia
TLDR
Electro-physical modellings for two kinds of excitation modes for excitation of paramecium with Ca2+ and K+ channels are found common to modelling of neuron with Na+ and Clchannels.
Computational modelling elucidates the mechanism of ciliary regulation in health and disease
TLDR
A detailed systems model for calcium, membrane potential and cyclic nucleotide-dependent ciliary motility regulation is developed and a novel type of ciliary excitability is described which plays the major role in ciliary movement regulation.
The interaction between metabolism and the plasma membrane potential, and intracellular pH
TLDR
Results suggest that the mitochondrial F0F1-ATPase might be involved in the mechanism by which glycolytic oscillations are driving the oscillations in the mitochondrial membrane potential and the cytosolic pH, and argue that the metabolism is driving them.
Pharmacological investigation of the bioluminescence signaling pathway of the dinoflagellate Lingulodinium polyedrum: evidence for the role of stretch‐activated ion channels
TLDR
Results are consistent with the presence of stretch‐ activated and voltage‐gated ion channels in the bioluminescence mechanotransduction signaling pathway, with spontaneous flashing associated with a stretch‐activated component at the plasma membrane.
Simultaneous coupling of phototaxis and electrotaxis in Volvox algae.
TLDR
The coupling of taxis is qualitatively explained based on the polarization of the swimming cells induced by the simultaneous photo- and electric stimulation, which did not emerge in the single stimulation experiments.
Positive and Negative Action Potentials in Paramecium Relating to Neurons
TLDR
It is found that common modellings are applied to excitation in paramecium and neuron with positive and negative potentials except ion channels.
Photobiomodulation by Infrared Diode Laser: Effects on Intracellular Calcium Concentration and Nitric Oxide Production of Paramecium
TLDR
The effect of both 808 and 980 nm diode laser irradiated with flat‐top hand‐piece on [Ca2+]i and NO production of Paramecium primaurelia and the only parameters to induce a release of stored calcium were the 980 nm and 64 or 96 J cm−2.
Integrative Neuroscience of Paramecium, a “Swimming Neuron”
Abstract Paramecium is a unicellular organism that swims in fresh water by beating thousands of cilia. When it is stimulated (mechanically, chemically, optically, thermally…), it often swims backward…
Microtubule Disruption does not Impair Learning in the Unicellular Organism Paramecium: Implications for Information Processing in Microtubules
TLDR
The results suggest that microtubules are probably not vital for the learning behavior in P. caudatum, and calls for a further revisitation of the microtubular information processing hypothesis.

TLDR
Measurements of membrane constants before and after deciliation and estimations of the cable constants of a single cilium suggest that the cilia of Paramecium may be fully isopotential along their length and with the major cell compartment.
Membrane noise in Paramecium
TLDR
The Paramecium surface membrane controls the locomotor activity, in particular ciliary reversal, by ionic conductance mechanisms like those in other excitable cells1,2.
Changes in Membrane Potential during Adaptation to External Potassium Ions in Paramecium Caudatum
TLDR
In the process of adaptation of Paramecium, there was a change in membrane potential: transfer of the cells to a lower K+ concentration caused depolarization of the potential, whereas transfer to a higher concentration produced a hyperpolarization.
Microdomain Ca2+ Activation during Exocytosis in Paramecium Cells. Superposition of Local Subplasmalemmal Calcium Store Activation by Local Ca2+ Influx
TLDR
It is suggested that Ca2+ mobilization from subplasmalemmal storage compartments, covering almost the entire cell surface, is a key event, and only the combination ofCa2+ flushes, primarily from internal and secondarily from external sources, can produce a signal triggering rapid, local exocytotic responses, as requested for Paramecium defense.

TLDR
The effect of removal of cilia is reported on the electro-physiological responses of paramecium to mechanical as well as some other stimuli.
Cold-sensitive Ca2+ Influx in Paramecium
TLDR
It is indicated that Paramecium cells have Ca2+ channels that are permeable to Ca2+, Ba2+ and Sr2+ in the anterior soma membrane and the channels are opened by cooling.

Results indicate that Parameciumcells have Ca 2+ channels that are permeable to Ca , Ba and Sr 2+ in the anterior soma membrane and the channels are opened by cooling.
Ca2+ release from subplasmalemmal stores as a primary event during exocytosis in Paramecium cells
TLDR
It is concluded that the primary effect of AED (as of caffeine) is the mobilization of Ca2+ from the subplasmalemmal pools which not only activates exocytosis but secondarily also spatially segregated plas malemmal Ca(2+)-dependent ion channels which serve to refill depleted stores.
Ca2+-dependent photoreceptor potential in Paramecium bursaria
TLDR
Photostimulation of deciliated specimens of chlorella-free P. bursaria elicited a transient depolarization of the membrane potential that is primarily caused by a transient increase in the membrane conductance to Ca 2+.
