A targeted extracellular approach for recording long-term …

WebA targeted extracellular approach (also known as loose-patch) accomplishes this objective. Because low resistance seals (<20 MOmega) do not influence the cell membrane and because the normal intracellular milieu is maintained, this approach is the least invasive method for monitoring the endogenous electrical activity of single cells. WebAnother challenge of extracellular recording is locating the targeted neurons in the absence of visual guidance, especially in deep brain structures. This usually necessitates stereotaxic methods of electrode positioning and the need to verify the location of the recording site post hoc. ...
