Localization of LPFC practiced-to-novel decision rule transfer. (A) Searchlight MVPA of decision rule four-way classifications (practiced → novel, whole block) within LPFC. The highlighted locations are clusters of “searchlights” (spheres with 9.6 mm radii) that consistently decoded which decision rule individuals were using. See Table 5 for a list of significant clusters. (B) Most of the searchlights were only able to decode a single pair-wise comparison, with two pair-wise comparisons as the maximum decoded by any single searchlight. This demonstrates an advantage of using MVPA with anatomical ROIs rather than searchlights, and suggests the Figure 2C result is due to spatially variable or distributed coding of rules within LPFC. (C) Localization of the pair-wise results, restricted to the significant four-way classification searchlights to correct for multiple comparisons.
