title: Conditioned effects of kindling.
abstract: Mild periodic electrical stimulation to any one of many brain sites leads to the development and progressive intensification of elicited motor seizures. Since its discovery in 1969, this kindling phenomenon has been widely studied both as a model of epileptogenesis and as a form of neuroplasticity, and recently there has been increasing interest in kindling as a model of the interictal (i.e. between-seizures) changes in emotionality that accompany certain forms of epilepsy. Despite the extensive use of the kindling model, little consideration has been given to the role played by the cues regularly associated with the delivery of the kindling stimulations. However, we have recently demonstrated that cues associated with the standard kindling protocol (e.g. the stimulation environment) produce conditioned effects on both the motor seizures and interictal behavior of rats and that some kindling sites, such as the amygdala, produce conditioned interictal behaviors that are defensive in nature. The implications that these findings have for the study of interictal behavioral changes in particular and to kindling research in general are discussed.
