There has been extensive research into methods of improving neural memory. Cycloserine, an antibiotic that has been, and continues to be, used extensively in the treatment of drug-resistant tuberculosis, was shown to be effective in promoting memory in small doses (much less than those used for tuberculosis) both in animals and humans. We, therefore, propose that cycloserine has the potential of enhancing the memory properties of neurones supplying pharyngeal muscles and propose to study the effect of using it on the severity of sleep apneas of the obstructive and central varieties.
