olfactory receptor neurons project into the olfactory bulb(part of brain) and cluster into glomeruli, the glomerulus communicates info from the olfactory neurons to the brain A given scent creates a telltale pattern of electrical activity that the brain recognizes.

Gate control theory

suggests that the spinal cord contains a neurological 'gate' that either blocks pain signals or allows them to continue on to the brain.
