Some researchers are so impressed by the depth and power of strong language that they are using it as a peephole into the architecture of the brain, as a means of probing the tangled, cryptic bonds between the newer, "higher" regions of the brain in charge of intellect, reason and planning, and the older, more "bestial" neural neighborhoods that give birth to our emotions.
Researchers point out that cursing is often an amalgam of raw, spontaneous feeling and targeted, gimlet-eyed cunning. When one person curses at another, they say, the curser rarely spews obscenities and insults at random, but rather will assess the object of his wrath, and adjust the content of the "uncontrollable" outburst accordingly.
Because cursing calls on the thinking and feeling pathways of the brain in roughly equal measure and with handily assessable fervor, scientists say that by studying the neural circuitry behind it they are gaining new insights into how the different domains of the brain communicate - and all for the sake of a well-venomed retort.
The urge to speak the unspeakable may be very complex. The person is gripped by a desire to curse, to voice something wildly inappropriate. Higher-order linguistic circuits are tapped, to contrive the content of the curse. The brain's impulse control center struggles to short-circuit the collusion between emotions system urge and the neural source, where decisions to act or desist from acting may be carried out, and it may succeed for a time.
Yet the urge mounts, until at last the speech pathways fire, the verboten is spoken, and archaic and refined brains alike must shoulder the blame.
