studies were made on the effect of the neuroexcitatory agent kainic acid , microinjected into raphe dorsal nucleus by glass micropipette and an air pressure system in doses ranging from 0.2 to 24.0 nmol ( in volumes from 0.05 microliter to 0.47 microliter ) , on the somatosensory evoked potentials and their cycles of recovery ( excitability ) obtained from cortex ( primary somatosensory and parietal associative ) , thalamus ( ventral posterolateral nucleus and centre median nucleus ) , mesencephalic reticular formation and raphe dorsal nucleus .
