We talk about the brain, but of course every brain is slightly different, and maybe there are some individuals or some conditions in which the electrical properties of neurons are such that they require more stimulus to fire, and that would lead to differences in brain function.
Vi snakker om hjernen men hver hjerne er lidt forskellig og måske er der nogle mennesker eller nogle omstændigheder hvor neuronernes elektriske egenskaber kræver mere stimulering for at transmittere og det ville give forskellig hjernefunktion.
