Neuropixels Probe Recording Activity in Neurons
This simulation shows how two different types of neural implants record the activity of brain cells. A single electrode [metal spike at left descending from top of image] picks up the activity of neurons only at its tip. The Neuropixels probe [long strip with checkerboard pattern] detects activity with electrodes all along its length.
