[Morphology of the posterior colliculus in epileptic hamsters]

In an inbred strain of Golden hamsters with audiogenic seizures, we have studied the collicular participation, planning a morphologic study of posterior colliculus central nucleus. The parameters used have been: number of neurons and glia, neuronal areas and area of all the colliculus. The measurement and the counts have been done in both sides and for to validate the results we have used an A.N.O.V.A.. In the epileptic group, there are a less number of neurons and a major correlation Nucleus/cytoplasm. The left-right correlations are positive for the neurons, while in the control group are for the glia. Although, the number of neurons in the epileptic animals are less, this are more active, which can be related to the participation of the colliculus in the audiogenic seizures.
