FIGURE 5.
Sign language‐specific voxels (resulting from the “sign language (SL) comprehension > SLA observation” contrast) in Broca's area and their function in nonsigners according to the BrainMap database which contained the results of 3,406 papers describing 16,901 experiments at the time of search. (a) Transverse plane of the left hemisphere at z = 14, showing voxels in left inferior frontal gyrus (IFG) spanning BA 44 and BA 45 which survived the “SL comprehension > SLA observation” contrast. (b) Sagittal plane at x = −48 showing this largest SL‐specific cluster (2,336 mm3) in left IFG spanning BA 44 and BA 45. (c) Number of studies with nonsigners in the BrainMap database that report peaks in voxels of the SL‐specific cluster in left IFG (BA 44 and 45), organized by behavioral domain. For details, see Appendix M. (d) Number of studies with nonsigners in the BrainMap database that report peaks in voxels of the SL‐specific cluster in left IFG (BA 44 and 45) organized by behavioral subdomain within the domain of cognition.
