Chronic neural probe for simultaneous recording of single-unit, multi-unit, and local field potential activity from multiple brain sites.
OBJECTIVE Drug resistant focal epilepsy can be treated by resecting the epileptic focus requiring a precise focus localisation using stereoelectroencephalography (SEEG) probes. As commercial SEEG probes offer only a limited spatial resolution, probes of higher channel count and design freedom enabling the incorporation of macro and microelectrodes would help increasing spatial resolution and th...
متن کاملComprehensive chronic laminar single-unit, multi-unit, and local field potential recording performance with planar single shank electrode arrays.
BACKGROUND Intracortical electrode arrays that can record extracellular action potentials from small, targeted groups of neurons are critical for basic neuroscience research and emerging clinical applications. In general, these electrode devices suffer from reliability and variability issues, which have led to comparative studies of existing and emerging electrode designs to optimize performanc...
متن کاملLocal Field Potential, Relationship to Unit Activity
Unit activity usually refers to timing of spikes elicited by individual neurons (single-unit activity, SUA) or local (r < 140 mm) population of neurons (multiunit activity, MUA; Buzsáki 2004). Although local field potential (LFP) reflects both subthreshold and spiking activities that are summed over larger population of neurons (r < 450 mm; Berens et al. 2008), usually it does not display discr...
متن کاملSurgical Implantation of Chronic Neural Electrodes for Recording Single Unit Activity and Electrocorticographic Signals
The success of long-term electrophysiological recordings often depends on the quality of the implantation surgery. Here we provide useful information for surgeons who are learning the process of implanting electrode systems. We demonstrate the implantation procedure of both a penetrating and a surface electrode. The surgical process is described from start to finish, including detailed descr...
متن کاملA new method for acquisition and analysis of single unit recording data
Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...
