"Cognitive Function
According to the United States Department of Agriculture (USDA) Agricultural Research Center, boron is essential for mental function, hand-eye coordination, attention span, perception and short and long-term memory.5Comparing spectral analysis of electroencephalographic data of low boron intake compared to high boron intake, there was a significant increase in the proportion of low-frequency activity and a decrease in the proportion of higher frequency activity (an effect often observed in general malnutrition or heavy metal toxicity). In addition, low boron intake resulted in "significantly poorer" performance on tasks emphasising: manual dexterity, eye-hand coordination, attention, perception, encoding and short- term memory and long-term memory" http://www.mineralresourcesint.co.uk/minerals/boron.php
