In Ted Chiang’s “Understand”, the protagonist, Leon takes a new hormone therapy (hormone K therapy) to regenerate neurons after an accident rendered him in a vegetative state. Leon regains consciousness and subsequently gains extreme intelligence and extraordinary motor skills. With his new superhuman abilities, Leon evades the pursuit of the US government and becomes enraptured with finding new Gestalt patterns in the universe.

Chiang explains how hormone K increases the number of synapses and, thus, the critical mass of the brain. Individuals are then able to use their new synapses and neural connections to their “fullest extent”, so they are able to increase their intelligence. However, the concept of Hebbian plasticity makes me doubt individuals would be able to use their new synapses to their “fullest extent”.
