A transient developmental window of fast-spiking interneuron dysfunction in a mouse model of Dravet syndrome

(Favero et al. 2018) Several years ago, researchers showed that Scn1a mutations in mice are primarily expressed in GABAergic interneurons, the inhibitory neurons that counteract excitatory neurons in the brain. A defect in these inhibitory neurons causes excess excitation, resulting in seizures and epilepsy in Dravet syndrome. However, that research was done primarily on brain …
