What are the differences between intracellular recording and extracellular recording in terms of their methodologies and applications?

Intracellular recording involves inserting a microelectrode into a single cell to measure its electrical activity, providing detailed information about the cell's membrane potential and ion channels. Extracellular recording involves placing electrodes outside of cells to record the collective activity of multiple cells, offering a broader view of neural activity in a region. Intracellular recording is more precise but limited to one cell, while extracellular recording captures activity from multiple cells simultaneously. Intracellular recording is often used for studying individual cell properties, while extracellular recording is useful for studying network activity and communication between cells.
