Department of Psychology, Laurentian University, Sudbury, Ontario, Canada.

The characteristics and consequences of limbic seizures evoked by single peripheral injections of lithium (3 mEq/kg) and pilocarpine (30 mg/kg) were investigated over a three-year period. The seizures occurred when 3 mEq/kg of lithium was followed 4 to 28 hours later by 30 mg/kg of pilocarpine. The seizures did not occur if the intervals were shorter or longer or if the pilocarpine preceded the lithium. The acute mortality or persistent aphagia and adipsia could be compensated by postseizure injections of acepromazine and a special milk-bread diet. Gender, age and preinjection environmental effects, but not hybrid genetics, influenced the seizure onset latency. Fifty to 100 days after the seizures massive lesions were found in the entorhinal-pyriform cortices, amygdala and selected thalamic groups.

UI MeSH Term Description Entries
D008032 Limbic System A set of forebrain structures common to all mammals that is defined functionally and anatomically. It is implicated in the higher integration of visceral, olfactory, and somatic information as well as homeostatic responses including fundamental survival behaviors (feeding, mating, emotion). For most authors, it includes the AMYGDALA; EPITHALAMUS; GYRUS CINGULI; hippocampal formation (see HIPPOCAMPUS); HYPOTHALAMUS; PARAHIPPOCAMPAL GYRUS; SEPTAL NUCLEI; anterior nuclear group of thalamus, and portions of the basal ganglia.

D011950 Receptors, Cholinergic Cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. Cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. Each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.
