چکیده

The complex dynamics of intracellular calcium regulates cellular responses to information encoded in extracellular signals. Here we study the encoding of these external signals in the context of the Li-Rinzel model. We show that by control of biophysical parameters the information can be encoded in amplitude modulation (AM), frequency modulation (FM), or mixed (AM and FM) modulation. We briefly discuss the possible implications of this role of information encoding for astrocytes.

Regulatory Role of Calcium Channel Blockers on Spontaneous Muscular Activity of Gastrothylax Crumenifer, A Rumen Amphistome

Major proportion of intracellular calcium (Ca 2+ ) is achieved through opening of calcium channels present in the plasma membrane which play an important role in regulating neuromuscular coordination and release of neurotransmitters from nerve terminals. Blockade of these calcium channels adversely affect contractile process and release of neurotransmitters in majority of the neuromuscular prep...

Comparison of the effect of quasitrapezoidal and rectangular pulses on bio- electrical activity, calcium spike properties and afterhyperpolarization potentials of Fl cells of Helix aspersa using intracellular recording

  While the effect of changes of stimulus waveform (quasitrapezoidal and rectangular current pulses) on nerve activation is clear, but there is no evidence on the effect of quasitrapezoidal pulses on ionic currents of cellular membrane. In the present study, the effect of depolarizing quasi-trapezoidal current pulses, in comparison with that of depolarizing rectangular current pulses, on firing...

Coarse-grained entropy rates quantify fast Ca2+ dynamics modulated by pharmacological stimulation.

Calcium (Ca2+) is an ubiquitous intracellular messenger which regulates cellular processes, such as secretion, contraction, and cell proliferation. A variety of cell types respond to hormonal stimuli with periodic oscillations of the intracellular free Ca2+ concentration ([Ca2+]i) which can be modulated in their frequency in a dose-dependent manner. The period of these well-studied oscillations...

P-94: The Effect of Calcium Ionophore A23187 and Ethanol on Parthenogenetic Activation of Mouse Oocytes in Presence of Hydrostatic Pressure and Cy-tochalasin B

Background: Parthenogenetic activation of mammalian oocytes using artificial stimuli is commonly used in various reproductive bio-techniques. Calcium ionophore is known to elevate intracellular calcium levels in the cytoplasm of oocytes through the influx of calcium from extracellular spaces. Ethanol promotes a single intracellular Ca2+ increase of greater and longer amplitude than the initial ...
