How and where simple volatile organic molecules act in the central nervous system to cause loss of consciousness and insensitivity to pain has eluded investigation; yet remarkable progress has been made recently towards identifying possible molecular targets through which the mechanism of anesthesia is tranduced.

Voltage-gated ion channels in epilepsies: circuit dysfunctions and treatments.
TIPS - Trends in Pharmacological SciencesEpileptic encephalopathies are generally considered to be functional disruptions in the balance between neural excitation and inhibition. Excitatory and inhibitory voltage-gated ion channels are key targets of antiepileptic drugs, playing a critical role

Voltage gating of ion channels
Quarterly Reviews of Biophysics, 1994Voltage-gated ion channels are membrane proteins that play a central role in the propagation and transduction of cellular signals (Hille, 1992). Calcium ions entering cells through voltage-gated calcium channels serve as the trigger for neurotransmitter release, muscle contraction, and the release of hormones. Voltage-gated sodium channels initiate the

Neurotrophins Differentially Regulate Voltage-Gated Ion Channels
Molecular and Cellular Neuroscience, 1997Neurotrophic factors profoundly affect neuronal differentiation, but whether they influence neuronal phenotype in instructive ways remains unclear: do different neurotrophic factors always trigger identical programs of differentiation or can each impose distinct functional properties even when acting upon the same population of target neurons?

Voltage Gated Ion Channels and Sleep
The Journal of Membrane BiologyIon channels are integral components of the nervous system, playing a pivotal role in shaping membrane potential, neuronal excitability, synaptic transmission and plasticity. Dysfunction in these channels, such as improper expression or localization, can lead to irregular neuronal excitability and synaptic communication, which may manifest as various ...

Diseases caused by voltage-gated ion channels
Molecular Aspects of Medicine, 1997Ion channels regulate the transfer of ions between the outer and the inner surface of the cell membrane. The opening of ion channels may be triggered by the binding of a ligand or variations in the membrane potential. Voltage-gated ion channels are an important class of such channels, that are involved in the generation and propagation of action ...

The kinetics of voltage-gated ion channels
Quarterly Reviews of Biophysics, 1994When Hodgkin & Huxley (1952) first embarked on the analysis of their voltageclamp data on the ionic currents in the squid giant axon, they hoped to be able to deduce a mechanism from it, but it soon became clear that the electrical data would by themselves yield only very general information about the class of system likely to be involved.

Molecular pathophysiology of voltage-gated ion channels
1996In addition to the clarification of the pathology of a whole group of hereditary diseases, the study of the consequences of these mutations at the levels of the whole system (patient), organ and cells (excised muscle specimens), and of the channel proteins has taught us that our current opinions on channel structure-function relations are far from ...

Both voltage-gated and ligand-gated ion channels are large protein molecules, as is the sodium pump Na,K-ATPase. In recent years the primary structure of a number of them has been determined, and by combining this information with the biophysical evidence, major advances have been made in our understanding of how they work at the molecular and ...

On the opening of voltage-gated ion channels
Physiology & Behavior, 2007Voltage-gated ion channels are key players in fast neuronal signalling. Detailed knowledge about channel gating is essential for our understanding of channel function in general and of drug action of channels in particular. Despite a number of recent atomic channel structures, the opening of voltage-gated channels is the subject of heated debates. Here
