Grin2aS/S mice are susceptible to brainstem-derived AGS that can be rescued by NMDAR antagonists.Fig. 4a Mortality curve showing that none of the Grin2a+/+ controls were affected, while audiogenic seizures (AGSs) followed by respiratory arrest (RA) were induced in all Grin2aS/S mice and in a subset of heterozygous Grin2a+/S mutants during the 11 kHz tone exposure [4 repetitions × 20 s tone, 2 s brake; pink squares; p < 0.0001 by Log-rank (Mantel-Cox) test]. b The c-Fos immunoreactivity was specifically increased in the hypothalamus (VMH), the inferior colliculus (IC), and periaqueductal gray (PAG) but not in the hippocampus (HPC) of a resuscitated Grin2aS/S mouse 90 min after AGS when compared to tone-exposed Grin2a+/+ littermates. c Memantine i.p. injection in Grin2aS/S mice, 3 h before tone exposure, rescued AGS susceptibility in Grin2aS/S mice. The rescue effect could still be observed in four out of eight, and in two out of eight, mice 27 and 51 h after memantine treatment, respectively. d Increased c-Fos immunofluorescence (in grayscale) in the medial amygdala (MeA) and the VMH of a Grin2aS/S animal with AGS (saline injection) compared to a memantine rescued Grin2aS/S littermate. In the paraventricular nucleus of the thalamus (PVT), the hippocampus (HPC) and cortex (Cx) there was no difference in c-Fos expression between memantine-injected and saline-injected animals (for fluorescence images, see Supplementary Fig. 5). e As in Fig. 4c but now MK-801 and saline are used for pre-treatment. The MK-801 effect was longer lasting compared to memantine and one out of four animals showed resistance to tone exposure even 4 days after MK-801 injection. f Decreased c-Fos DAB immunosignal in an MK-801 AGS-rescued Grin2aS/S animal (bottom) in the medial amygdala (MeA), the VMH and the PVT when compared to saline-injected Grin2aS/S littermate (top).
