The aim of this study was to investigate the infrastructure of the reticular thalamic nucleus (RTN) in rats
of WAG/Rij strain, an established model for human absence epilepsy. Most RTN neurons are medium-to large-sized and have either
dark or light appearance, depending on their functional state. Moreover, small-sized neurons with short axons are present,
their characteristics being described for the first time.
Key words: the reticular thalamic nucleus, absence epilepsy, rats of the WAG/Rij strain
