Using a new method which combines a brain microdialysis technique and measurement of nitrite/nitrate levels by the Griess reaction, it has been proven that activation of N-methyl-D-aspartate (NMDA) receptors in the cerebelli of rats which had been under non-anesthetic and freely moving conditions induces the release of nitric oxide (NO). Since L-N(G)-monomethylarginine (L-NMMA), which competitively blocks NO synthesis from L-arginine, significantly inhibited the release of nitrite/nitrate from the rat cerebellum, these results indicate that the new method is capable of measuring NO formation from L-arginine following the stimulation of NMDA receptors. This method should prove useful for investigating the relation between brain functions such as behavior, learning and memory and NO in the central nervous system.
