= Tetrode (biology)
{wiki=Tetrode_(biology)}
In biology, a "tetrode" refers to a type of electrode that is used to record electrical activity from multiple neurons simultaneously. The term is commonly used in neurophysiology, particularly in studies involving the brain and nervous system. A tetrode typically consists of four individual electrodes arranged in a configuration that allows for better spatial resolution and the ability to differentiate between the signals of nearby neurons.
