Accelerated critical neural pathway formation is a medical procedure, a type of genetic engineering, designed to enhance the formation of cognitive pathways in the Human brain. The procedure can result in tremendously increased intelligence in areas such as analysis, deduction, induction, and theoretical exposition. There is also, however, a high likelihood of dramatic and often unpredictable side effects on the personality of the patient. These can include, but may not be limited too: anti-social personality, violent tendencies, a reversion to child-like states of interaction, and the appearance of a catatonic state.
In 2375 Doctor Karen Loews took several of her patients, all of whom had undergone accelerated critical neural pathway formation, to Deep Space 9 for interaction with Julian Bashir. Dr. Lowes believed that because Bashir had also undergone genetic engineering, but without the associated side-effects, that he might be able to help some of her patients relate to the outside world in a normal fashion.
