Extracellular research measures and characterizes the electrical properties of cells and tissues, particularly neurons and neuronal tissue. Measurements are usually performed either in the extracellular fluid near the cell of interest, or non-invasively. These measurements can be divided into three main groups, which include single/multiple unit recordings, whole nerve recordings, and extracellular field potentials. Epithelial voltage clamping recording can also be classified under extracellular recordings.

Easily acquire and analyze extracellular potentials from nerves and brain slices, and seamlessly assess conscious neural activity, extracellular spikes, and extracelllular field potentials, by using a combination of the PowerLab 35 series and our extracellular neural amplifiers.
