Potential, Spike

 

a large and sudden change in electrical potential that accompanies excitation in nerve and muscle cells and fibers. In physiology, the term “spike potential” is often used as a synonym for action potential. In clinical electroencephalography spike potential refers to gross potentials reaching 10 milliseconds in duration that are outwardly similar to the action potential of a nerve. These potentials are detected in an electrocorticogram taken with certain pathological disturbances, particularly epilepsy.

We have therefore studied whether either the transient use of tricaine or telencephalon removal have any residual effects on resting potential, spike height, and current needed to elicit a spike.
