The cost of an action potential
Journal of Neuroscience Methods, 2000Neuronal modules, or 'cell-assemblies', comprising millions of mutually interconnected cells have been postulated to form the basis of many functions of the brain, such as mood, sleep, hunger, vigilance, and more. Depending on the extent of the module, neurocommunication in cell-assemblies might exceed metabolic resources. A medium-size (10000 neurons)

Neurobiology of Learning and Memory, 2000
Neurons compute in part by integrating, on a time scale of milliseconds, many synaptic inputs and generating a digital output-the "action potential" of classic electrophysiology. Recent discoveries indicate that neurons also perform a second, much slower, integration operating on a time scale of minutes or even hours.

New Progestins and Potential Actions
Journal of the Society for Gynecologic Investigation, 2000Newer, nonsteroidal, orally active, tissue-selective progestins are being developed through a molecular approach to compound selection with human progesterone receptor (hPR) serving as the molecular target. The co-transfection and binding assays are used to test receptor selectivity and cross reactivity with a panel of receptors.

Action Potential in Charophytes
2007The plant action potential (AP) has been studied for more than half a century. The experimental system was provided mainly by the large charophyte cells, which allowed insertion of early large electrodes, manipulation of cell compartments, and inside and outside media.

In this chapter we meet the action potential, the fundamental electrical signalling mechanism used by the body. We introduce the cycle of ion movements associated with the generation of an action potential and the role of different ion gates. We then analyse the system of action potential generation in terms of a simple electrical circuit model.

1974
Bernstein (1902, 1912), the founder of the modern membrane theory, regarded the action potential as the “negative wave” of the resting potential. He considered that during stimulation of a nerve or muscle fiber certain chemical changes which give rise to a reversible increase in the ionic permeability of the cell membrane take place at the point of ...

An ideology is defined as a set of ideas that “explains and evaluates social conditions, helps people understand their place in society, and provides a program for social and political action” (Ball & Dagger, 2011, p. 4). As such, these concepts underpin the actions of various groups and organizations, including that of the Anonymous hacker group ...
