Figure 8.

The laminar distribution of multisensory neurons and their integrative properties. (a) Multisensory neurons (MS, subthreshold and bimodal; black) predominated in all layers of the LRSS (dotted line indicates 50% of neuronal sample/layer) while proportionally fewer unisensory (T=tactile, dark grey; A=auditory, light grey) neurons occurred in each layer. (b) Multisensory neurons across all layers exhibited integrated responses to combined auditory-tactile stimulation, as well as a higher incidence of response depression (Depr) than response enhancement (Enh). (c) The average (± se) magnitude of response enhancement or response depression was fairly similar across all cortical layers.
