We found that Grin2a and Akap11 mutant mice possess several EEG features shared with human schizophrenia and bipolar disorder patients, including elevated gamma oscillations at rest [25, 26], attenuated auditory steady-state responses (ASSR) at gamma frequencies [27, 28], and changes in sleep spindle density [29, 30]. This evidence concerns the gene GRIN2A and bipolar disorder.
