Source: Fallegger, F. et al., Subdural Soft Electrocorticography (ECoG) Array Implantation and Long-Term Cortical Recording in Minipigs. J. Vis. Exp. (2023). This video demonstrates the implantation of a soft electrocorticography array and the long-term cortical recordings in a minipig. It outlines the steps involved in surgically implanting the array over the minipig's auditory cortex and recording both baseline and sound stimulus-evoked neuronal action potentials.
