Genetic Influences on Seizure Susceptibility in Rodent Models
Summary
Seizure susceptibility in rodents is governed by a complex interplay of multiple genes and environmental factors. Inbred strains, substrains and genetically engineered lines have revealed that baseline excitability, seizure threshold and the propensity to develop chronic epilepsy vary markedly according to genetic background. Chemoconvulsant models such as kainic acid, pentylenetetrazole and flurothyl administration yield reproducible seizures, while audiogenic protocols induce sound-triggered convulsions in susceptible strains. Repeated stimulation paradigms uncover processes of epileptogenesis, whereby initial seizures alter neural circuits and gene expression to facilitate later events. Mapping studies in structured populations, including recombinant inbred panels and diversity outbred stocks, have identified quantitative trait loci related to ion channels, synaptic organisers and transcriptional regulators. Targeted deletions and transgenic overexpression of candidate genes confirm the roles of potassium, sodium and calcium channel subunits in modulating network excitability. Collectively, these models illuminate the polygenic architecture of seizure vulnerability and underpin efforts to translate genetic discoveries into novel therapeutic strategies.

Genetic Influences on Seizure Susceptibility in Rodent Models publication trend
The graph below shows the total number of articles in genetic influences on seizure susceptibility in rodent models across all publications each year (not limited to Nature Index journals).
Technical terms
Seizure threshold: The minimum intensity of a stimulus required to evoke a convulsive event.
Status epilepticus: A prolonged or rapidly recurring seizure state that constitutes a neurological emergency.
Kindling: A process by which repeated subconvulsive stimuli induce increasing seizure susceptibility and eventual spontaneous seizures.
Epileptogenesis: The sequence of molecular and cellular changes that converts a non-epileptic brain into one prone to recurrent seizures.
Quantitative trait locus (QTL): A genomic region statistically associated with variation in a measurable phenotype such as seizure susceptibility.
Audiogenic epilepsy: Seizure induction by auditory stimuli in strains genetically predisposed to sound-triggered convulsions.
Chemoconvulsant: A chemical agent used experimentally to induce seizures for the study of epilepsy mechanisms.
