Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
Kainic acid can be used to create epilepsy models and can be administered systemically, into the hippocampus, or amygdala, and is reproducible in various species. The systemic Kainic acid model closely mimics the manifestations of human temporal lobe epilepsy. When injected at a dose of 5 nM into the neostriatum, substantia nigra, or cerebellum, over half of the Kainic acid disappears from the injection site and brain within 0.5 hours, with radioactivity detected in other brain regions at concentrations lower than 7 pmol/mg[3][4][6].
Administration: 10 μg in 5 μL • i.c.v.
(2) After the operation, skin was sutured, and keep the mice under a warming place until they wake up.
(3) 48 hours after lateral ventricle injection, the mice are anaesthetized using Isoflurane and then sequentially intracardially perfused with saline and PFA (4%, 30 mL). Rapidly remove The mouse brain processed for paraffin embedding or frozen sections.
Histology analysis: Showed Triangulated pyknotic nuclei and cytoplasmic shrinkage in the hippocampal neuron, and induced neuronal loss.

KA treatment: Lidocaine (3%) and KA (2 mg/mL) were infused bilaterally into the LC via delivery cannulas connected to the cannula drug delivery system in a 0.2 μL volume per side at a rate of 0.1 μL/10 s 30 min after training. Pharmacological inhibition of the LC reduced conditioned fear memory in mice, whereas activation of the LC reversed the SGB-induced reduction in conditioned fear memory [n = 8, F (3, 28) = 53.26, P < 0.0001; NS + Vehicle vs. NS + Lid, n = 8, P < 0.0001; SGB + Vehicle vs. SGB + KA, n = 8, P < 0.0001].
