For the able - bodied population, this world sits snugly in the palm of their hands,
evolving by the millisecond on the ubiquitous smartphone that offers endless communication possibilities with a simple swipe.
The channel - like property could have
evolved, says Edwards, to meet the important need of moving large amounts of glutamate quickly, for while the other neurotransmitters are involved in modulating behaviors, such as mood, and therefore don't need to act with
millisecond speed, glutamate functions
by rapid - fire communication between closely placed nerve cells, and could require the fast action of the channel mechanism.
