Local Field Potentials

Local Field Potentials (LFPs) are electrical signals generated by the collective activity of neurons in a specific brain area. When neurons communicate, they produce small electrical currents that can spread through surrounding tissue. LFPs capture these combined signals, reflecting the overall brain region's neural activity, such as synchronized firing or rhythmic oscillations. They are often recorded using electrodes placed on or near the brain tissue and provide valuable insights into brain functions like perception, movement, and cognition. Essentially, LFPs offer a window into the coordinated electrical activity of neurons in a localized region.
