Synaptic plexi of U-fibre layer beneath focal cortical dysplasias: Role in epileptic networks.
CONCLUSION: U-fibre synaptic plexi contribute to excitatory circuitry in the cortex and thus to epileptic networks. Deep white matter neurones form local, less integrated plexi except transmantle dysplasias continuous with cortex. U-fibres may be a barrier to axonal penetration from deep heterotopia. Hypermetabolic neurones suggest repetitive ictogenic depolarizations. Gyral resections should include the U-fibre layer. Neuropathology reports should describe subcortical plexi. Synaptophysin immunoreactivity is a valuable supplement for this purpose.
