Schematic representation of human and rodent EEG electrode placement, ERPs and gamma oscillations.

A) Human scalp EEG array using the International 10–20 System for electrode placement; B) example of rodent EEG using implanted tripolar electrodes; C) schematic representation of stereotypical auditory-evoked ERP with characteristic positive and negative voltage deflections. ERP latencies and peaks can vary according to electrode placement, experimental paradigm and species; D) example of neural oscillations-gamma oscillations at baseline and following auditory stimulus, contrasting wildtype and GluN1 knockout mice. S – stimulus, KO – knockout, WT – wildtype. Panel B adapted from Connolly et al. (2003) with permission, panel C adapted from Gandal et al. (2012b) with permission.
