alexa Updated List of High Journal Impact Factor Action Potential Journals

OMICS International organises 3000+ Global Conferenceseries Events every year across USA, Europe & Asia with support from 1000 more scientific societies and Publishes 700+ Open Access Journals which contains over 50000 eminent personalities, reputed scientists as editorial board members.

Action Potential

As per available reports about 19 journals, 10 Conferences and 14 Workshops are presently dedicated exclusively to action potential and about 382 articles are being published on the action potential. In terms of research annually, USA, India, Japan, Brazil and Canada are some of the leading countries where maximum studies related to action potential are being carried out. As reported in above mentioned article, in physiology, an action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called excitable cells, which include neurons, muscle cells, and endocrine cells, as well as in some plant cells. In neurons, they play a central role in cell-to-cell communication. In other types of cells, their main function is to activate intracellular processes. In muscle cells, for example, an action potential is the first step in the chain of events leading to contraction. In beta cells of the pancreas, they provoke release of insulin. Action potentials in neurons are also known as "nerve impulses" or "spikes", and the temporal sequence of action potentials generated by a neuron is called its "spike train". A neuron that emits an action potential is often said to "fire".

Action potentials are generated by special types of voltage-gated ion channels embedded in a cell's plasma membrane. These channels are shut when the membrane potential is near the resting potential of the cell, but they rapidly begin to open if the membrane potential increases to a precisely defined threshold value. When the channels open (in response to depolarization in transmembrane voltage), they allow an inward flow of sodium ions, which changes the electrochemical gradient, which in turn produces a further rise in the membrane potential. This then causes more channels to open, producing a greater electric current across the cell membrane, and so on. The process proceeds explosively until all of the available ion channels are open, resulting in a large upswing in the membrane potential. The rapid influx of sodium ions causes the polarity of the plasma membrane to reverse, and the ion channels then rapidly inactivate. As the sodium channels close, sodium ions can no longer enter the neuron, and then they are actively transported back out of the plasma membrane. Potassium channels are then activated, and there is an outward current of potassium ions, returning the electrochemical gradient to the resting state. After an action potential has occurred, there is a transient negative shift, called the after hyperpolarization or refractory period, due to additional potassium currents. This is the mechanism that prevents an action potential from traveling back the way it just came.

An academic journal – hosted by OMICS International – a pioneer in open access publishing–and is listed among the top 10 journals in action potential. Each year research scientists have noticed a rise in the number of congresses being held in this field.

OMICS International hosts over 700 leading-edge peer reviewed Open Access Journals and organize over 3000 International Conferences annually all over the world. OMICS International journals have over 3 million readers and the fame and success of the same can be attributed to the strong editorial board which contains over 50000 eminent personalities that ensure a rapid, quality and quick review process. OMICS International signed an agreement with more than 1000 International Societies to make healthcare information Open Access.
