An open question for consideration by the group forum.
A psychologist from UCLA claimed that he 'invented' comodulation in
1994. I have found references in the 80s - many in auditory processing:
the CMR or 'comodulation masking release'; others in simultaneous
excitation and inhibition of cortical neurons. Hall's study from 1987
and BC Moore's review on several applicaitons dating from 1990 are just
two published studies that pre-date this claim.
Can anyone shed light on this for me? As a broadly, though not
precisely defined function, correlative modulation or comodulation is a
valuable tool. However, I cannot satisfy myself that any precise
formalism exists now to describe this cross-channel correlation measure.
Can you name the mystery psychologist? Can you rationalize his claim?
Can anyone point to a precise definition of comodulation as a rigorous
Thank you in advance,
