Therapy target
| | | |
| mice with Scn1a haploinsufficiency display hyperactivity, stereotyped behaviors, social interaction deficits, and impaired context-dependent spatial memory | |
Scn1a+/- mice exhibit hyperactivity, increased anxiety, and increased stereotyped behaviors, which are phenocopies of autistic traits in Dravet sdr |
