title: Focal cortical seizures prevent HRP and HRP-WGA labeling only in neurons bidirectionally connected to the cortex.
abstract: Intracortical implants of polyacrylamide gel containing horseradish peroxidase labeled cortical efferents and perikarya in some cortical areas and a number of subcortical formations. When epileptogenic penicillin was added to the gel, no labeling was seen in the efferents and cell bodies of the cortex, thalamus, or claustrum, whereas the magnocellular nuclei of the basal forebrain, raphe nuclei and locus coeruleus did contain the label.
