Targeted extracellular recording
WebMay 23, 2024 · Extracellular recording methods, such as multielectrode arrays and multitransistor arrays, are noninvasive and allow long-term and multiplexed measurements. However, extracellular recording sacrifices the one-to-one correspondence between the cells and electrodes, and also suffers from significantly reduced signal strength and quality. 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.

WebJun 26, 2013 · Pre-visualization of the target neuron is particularly useful for challenging recording conditions, for which classical single-cell recordings are often prohibitively difficult8-11. 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. ...
