The tonopotic organization of the auditory cortex has
been a great interest for neuroscientists to understand
the encoding of sounds in the brain. An auditory
experimental design consisting of three random frequency
ranges and a continuous sampling scheme was presented to
study the tonotopic organization in awake marmoset,
which had been shown to have great potential as a novel
animal model for auditory studies. For the first time,
we demonstrated the robust BOLD fMRI response as well as
the tonotopic map in auditory cortex of awake marmosets.
