Kainic acid receptors mediate EPSCs at several hippocampal synapses 1,2,3,4,5. Application of exogenous agonists of this class of receptors has also been shown to depress both excitatory and ...

Sudden cardiac death resulting from fibrillation -- erratic heartbeat due to electrical instability -- is one of the leading causes of death in the United States. Now, researchers have discovered a ...

The transport of ions is essential to maintain electrophysiological balance on either side of the membrane, called osmotic balance, which is needed for signals to be transduced from their chemical ...

Historically, researchers impaled giant squid, snail, and frog axons with electrodes to study nerve function by measuring ion channels. Today, electrophysiologists have enhanced their ability to ...

The QRS complex consists of the Q wave, the R wave and the S wave. The QRS complex comes after the P wave when the SA nodal action potential travels through the AV node to the ventricles to cause ...

An arrhythmia (also termed cardiac dysrhythmia) is described as an irregular heartbeat caused by aberrant electrical activity in the heart. There are multiple categories of arrhythmia, each of which ...
