Partially isolated cortex (“undercut”) is an efficient animal model of posttraumatic epileptogenesis. Here we demonstrate how to make a novel surgical device and use it to make more precise and consistent lesions to generate this model.

Here, we describe the preparation of rhinal cortex-hippocampus organotypic slices. Under a gradual and controlled deprivation of serum, these slices depict evolving epileptic-like events and can be considered an ex vivo model of epileptogenesis. This system represents an excellent tool for monitoring the dynamics of spontaneous activity, as well as for assessing the progression of neuroinflammatory features throughout the course of epileptogenesis.

Here, we present a systematic approach for developing physiologically relevant, sensitive and specific in vivo assays for interpreting variation in human pathology. Transient genetic manipulation via microinjection of WT and mutant human mRNA and morpholino (MO) antisense oligonucleotides harness the tractability of the developing zebrafish embryo to rapidly assay pathogenic mutations, especially, but not exclusively, in the context of human developmental disorders.

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules. Skeletal Model Simpler two-dimensional representations of chemical compounds are accomplished using skeletal models. The illustration shows only the molecular framework or bonds without explicitly showing the atoms. In this representation, many of the carbon atoms...

FAQs
Epileptogenesis Model research commonly organizes disease progression around three linked levels: an initiating injury or genetic disturbance, altered neuronal excitability and synaptic signaling, and broader network reorganization. These levels are not isolated events. Early molecular and cellular changes can reshape circuit behavior, while circuit changes may support spontaneous seizures. Tracking their sequence helps researchers distinguish causes from later consequences.
Changes in neuronal excitability and synaptic signaling provide a mechanistic link between an initiating disturbance and abnormal network activity. They show how individual neurons and their connections may become more likely to participate in seizure-generating activity. Studying these changes allows researchers to connect molecular or cellular events with later circuit-level behavior and identify processes that could be targeted before recurrent seizures become established.
Animal, cellular, and computational models examine different levels of the same disease process. Animal systems can represent interacting brain circuits and disease progression, cellular systems focus on neuronal and synaptic mechanisms, and computational systems can represent network behavior or test mechanistic relationships. Using these approaches together helps connect observations across scales rather than relying on one experimental perspective.
A study generally selects an animal, cellular, or computational system, incorporates an initiating injury or genetic disturbance when appropriate, and follows subsequent changes in excitability, synaptic signaling, and network organization. Researchers then examine whether the system develops seizure-related activity and compare findings across stages. This staged workflow supports investigation of progression instead of measuring seizures as an isolated endpoint.
These models can reveal molecular, cellular, and circuit-level changes that accompany disease progression, while also helping researchers evaluate potential biomarkers. Biomarkers are measurable features that may indicate an evolving pathological process or its stage. Such information can connect early brain changes with later spontaneous seizures and help determine whether an intervention affects disease development rather than only seizure expression.
They are especially useful when the research goal is to prevent or modify epilepsy development, rather than simply suppress seizures after the condition is established. By examining changes before and after recurrent seizure activity emerges, researchers can test whether a therapy influences underlying progression. In neuroscience, this supports more precise treatment strategies linked to specific molecular, cellular, or circuit mechanisms.
