Example of a CO stained barrel field in an RI (BXD63) mouse. (A) Photomicrograph of the entire barrel field. (B) Line drawing showing prominent barrel subfields: PMBSF posterior medial barrel subfield, ALBSF anterior lateral barrel subfield, LJ lower jaw, FBS forepaw barrel subfield, and HBS hindpaw barrel subfield. Individual PMBSF barrels are outlined and labeled. Five prominent rows of barrels (A through E) are seen. In addition, four posteriorly located straddler barrels (α, β, γ, δ) are also seen. Total area of PMBSF (barrels and septal regions between barrels) was measured as outlined in figure. Scale 500 μm.
