CMEA: Customizable Multielectrode Array for Local Field Potential Recordings

Oct 11, 2023

Collecting local field potential (LFP) data to study rhythmic brain activity can be expensive, and building the necessary tools can be difficult and time consuming.  Richard Quansah Amissah and colleagues from the Khokar Lab have developed customizeable multielctrode arrays (CMEA) that can be used for LFP data collection in various brain regions. In addition to LFP, the CMEAs can be used to record single- and multi-unit activity. They describe the steps and materials needed to build a 16-channel array that is lightweight, affordable, and takes less than one hour to build. Importantly, CMEAs are compatible with different neural data acquisition systems. Whether you are looking to collect preliminary data before investing in more expensive electrodes, or looking for an overall more cost-effective way to collect your data, CMEAs are an accessible and low-cost alternative to collect neural data in freely behaving animals.
