(Bremmer, et al. 2001; Downar, et al. 2000). Some studies Ofsomatosensory processing
have reported activity in STS (Burton, et al. 2006; Disbrow, et al. 2001; Golaszewski, et
al. 2OO2)but it is unclear Ifsomatosensory, auditory and visual responses occur in
human STSms as they do in macaque STP.

The primary goal of our experiments was to test the hypothesis that human
STSms responds to somatosensory, auditory and visual stimulation. A secondary goal,
contingent on the presence of somatosensory responses in STSms, was to test the
hypothesis that multisensory integration between touch and Sound occurs in STSms.
Because a benchmark of multisensory integration is a differential response to
multisensory compared with Unisensory stimulation (Beauchamp 2005b), we compared
the response to multisensory and unisensory somatosensory and auditory stimulation.
The final goal of the experiments was to characterize somatosensory and visual
responses in STSms to a broad range of stimuli to allow an assessment of whether
human STSms has similar response properties as macaque STP, above and beyond

Methods

We used a single subject approach, identifying STSms on cortical surface models
created for each individual subject. To allow us to devote the bulk of the experimental
time to studying somatosensory responses in STSms, we used functional localizers (Saxe,
et al. 2006) to map visual responses in STSms in Experiment 1 and visual and auditory
