Exemplary pictures of MEA chips and electrodes of different shapes. A multielectrode array from Multichannel Systems© with 60 electrodes and chamber containing cell culture medium. B Arrangement of electrodes in an array of 60. C Clusters of myenteric neurons growing on planar microelectrodes, scale bar 50 μm. D SEM picture of a planar electrode, scale bar 10 μm. E and F SEM pictures of nanostructured MEA electrodes with tube- and mushroom-like nanostructures, scale bars 2 and 5 μm, respectively (insets: magnification of nanostructures, scale bar: 200 nm; taken with permission from Decker et al., 2019)
