Special Issue Information

Dear Colleagues,

Animal models are powerful tools for investigating the key principles and underlying mechanisms of diseases and disorders. The use of animal models has allowed us to conduct various types of experiments and interrogate the mechanisms underlying diseases and disorders in manners that are unfeasible and unthinkable to apply to human patients. The usefulness of any animal model depends on various parameters such as predictive validity, symptoms, similarity to human conditions, and tractability. To date, various mammalian and non-mammalian animal models of neurological disorders have been established and characterized. They reflect the genetics, behavioral, and/or electrophysiological phenotypes of human patients.

There are various neurological disorders but, in this issue, we are mainly focusing on five prominent disorders: Parkinson’s disease, Alzheimer’s disease, epilepsy, Huntington’s disease, and schizophrenia. This Special Issue will provide experimental evidence, updated views, and new treatment strategies regarding these disorders. Critical discussions on the advantages and limitations of animal models used to mirror these neurological disorders are also welcome. This Special Issue will cover original articles and reviews on every aspect of mammalian and non-mammalian animal models of Parkinson’s disease, Alzheimer’s disease, epilepsy, Huntington’s disease, and schizophreniaThis may include (but is not limited to) genetic, pharmacological, chemogenetic (such as DREADDs), and optogenetic models of neurological disorders. In this issue, we also encourage authors to submit work on rare neurological and developmental disorders which affect the brain, spinal cord, or peripheral nerves.

Moreover, we encourage submissions on novel tools and methods related to animal models of the abovementioned neurological disorders as well. Tools and methods will only be considered if they are novel, well documented, discussed, and have the potential to be useful to the scientific world.

This study investigates audiogenic epilepsy in Krushinsky-Molodkina (KM) rats, questioning the efficacy of conventional EEG techniques in capturing seizures during animal restraint. Using a wireless EEG system that allows unrestricted movement, our aim was to gather ecologically valid data. Nine male KM rats, prone to audiogenic seizures, received implants of wireless EEG transmitters that target specific seizure-related brain regions. These regions included the inferior colliculus (IC), pontine reticular nucleus, oral part (PnO), ventrolateral periaqueductal gray (VLPAG), dorsal area of the secondary auditory cortex (AuD), and motor cortex (M1), facilitating seizure observation without movement constraints. Our findings indicate that targeted neural intervention via electrode implantation significantly reduced convulsive seizures in approximately half of the subjects, suggesting therapeutic potential. Furthermore, the amplitude of brain activity in the IC, PnO, and AuD upon audiogenic stimulus onset significantly influenced seizure severity and nature, highlighting these areas as pivotal for epileptic propagation. Severe cases exhibited dual waves of seizure generalization, indicative of intricate neural network interactions. Distinctive interplay between specific brain regions, disrupted during convulsive activity, suggests neural circuit reconfiguration in response to escalating seizure intensity. These discoveries challenge conventional methodologies, opening avenues for novel approaches in epilepsy research and therapeutic interventions. Full article
