Small shifts in blood sodium may influence human brain excitability

This exploratory study in healthy young adults found that plasma sodium levels within the normal clinical range are significantly associated with resting motor threshold, an indirect measure of corticospinal excitability. Lower sodium concentrations were linked to lower thresholds, suggesting subtle physiological variation in electrolytes may relate to interindividual differences in brain excitability.
