Figure 1: Ethanol potentiates a potassium current induced by rapid activation of GABA B receptors in cerebellar granule cells in culture. To assess ethanol effects on GIRKs coupled to different ...

Potassium channels are openings that allow charged potassium atoms to cross the cell membrane. Voltage-gated potassium channels—which open only when a specific voltage is reached across the cell ...

Ion selectivity is an important property of cell membrane ion channels. For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready ...

Previous research has suggested that neurons in multiple sclerosis (MS) exhibit metabolic exhaustion, believed to be caused by chronic hyperexcitability, which can lead to neurodegeneration.

Leaflet movements in the mimosa-family tree Samanea saman stem from coordinated volume changes of cells in the leaf motor organs in the adaxial and abaxial motor cells ("flexors" and "extensors").

A University of Vermont study suggests that the astrocytic BK channel is an important participant in the cellular process responsible for signaling regional blood flow changes in the brain, providing ...

The underlying cause of multiple sclerosis, a disease that affects 2.5 million people worldwide, has proven elusive despite more than a century of research. Evidence indicates that multiple sclerosis ...
