Abstract
Using an experimental model of neonatal recurrent seizures
we investigated the influence of epileptic seizures in the
various forms of synaptic plasticity in neurons of the somatosensory
cortex. We found that early seizures do not affect the
post-tetanic potentiation of the amplitude of the postsynaptic
potentials and the depression of postsynaptic potentials during
high-frequency stimulation. However they result in the chronic
increase of the long-term potentiation of synaptic transmission.
These changes of synaptic plasticity may affect the processing
of the sensory information in patients with a history of recurrent
seizures during early development.
