The auditory cortex is typically defined as that portion of the cortex containing neurons that respond to sound. This definition is
adequate in a narrow context, but does not take into account sufficiently the subtleties associated with more complex behaviors and cognitive
processes. Thus, it is easy to demonstrate that cortical regions essentially unrelated to sound processing may nevertheless be activated
by an auditory stimulus; conversely, it is possible to demonstrate responses within classical auditory cortical regions in the
complete absence of sound. We give several examples that indicate that responses in auditory cortex cannot be predicted based solely
on knowledge of stimulus features. Rather, factors such as memory, attention, and mental imagery can be shown to play a major role
in modulating or producing neural responses within auditory cortex. We argue that the interactions between classically defined auditory
regions and other sensory, motor, and cognitive systems underlie many behaviors of interest; and that a more complete understanding of
these processes will emerge from a consideration of the distributed nature of auditory cortical function.
