The Fiber Disease

... most reports indicate that the basal extracellular glutamate sampled with this technique is unperturbed by TTX or by removal of calcium from the perfusion medium. This has led many to conclude that microdialysis has limited utility for sampling the neurotransmitter pool of glutamate. However, ...
