Animal Models of Audiogenic Seizures
Summary
Animal models of audiogenic seizures have been instrumental in elucidating the neural circuits and genetic factors underlying reflex epilepsy. In these models, high‐intensity acoustic stimuli provoke a stereotyped sequence of behaviours—initial wild‐running followed by clonic and tonic convulsions—mediated primarily by hyperexcitability within the inferior colliculi and associated brainstem pathways. A range of genetically predisposed strains, including Krushinsky–Molodkina rats, Wistar Audiogenic Rats and GASH/Sal hamsters, display distinct susceptibility profiles that reflect alterations in glutamatergic, GABAergic and dopaminergic neurotransmission. These preparations facilitate the study of seizure propagation, synaptic and receptor dynamics, and the role of neuroinflammation. They serve as platforms for preclinical screening of antiepileptic agents, investigation of neuromodulation approaches such as vagus nerve stimulation, and examination of behavioural comorbidities like social deficits. Recent advances in transcriptomics, protein mapping and receptor binding assays continue to deepen our understanding of the molecular mechanisms that govern audiogenic susceptibility, informing translational strategies for diagnosis and therapy.

Technical terms
Audiogenic seizure: A convulsive event triggered by high-intensity sound stimuli in genetically or pharmacologically susceptible animals.
Wild-running: The early, panic-like phase of an audiogenic seizure characterised by rapid, uncoordinated locomotion.
Inferior colliculus: A midbrain auditory nucleus central to processing acoustic stimuli and initiating audiogenic seizures.
Vagus nerve stimulation: A neuromodulation therapy involving electrical pulses delivered to the vagus nerve to reduce seizure frequency and severity.
