This is a technical overview of research on "frequency processing", which has become a popular topic in neurophysiology and cognitive science. It collects papers from several researchers that offer an up-to-date overview of empirical studies and theoretical models.

Our mind works well because it is good at creating associations. Associations depend on frequency, the frequency with which two events co-occur (the occurrence of one is followed or preceded by the occurrence of the other).

All sensory inputs are unique, but it would be unfeasible for our mind to treat each sensory input as a separate event. It is much easier to deal with "categories" of sensory inputs. We build categories to simplify the world. We build categories based on frequencies. So the processing of frequencies is key to our survival.
