(A and B) Cortical cell-type-specific inputs to the CLA (A) and CLA outputs to isocortex (B). The CLA (in white) is an anteroposterior elongated and curved strip in each hemisphere. Red stars in the CLA represent principal neurons. These are the same in (C) and (D). Solid and dashed arrows represent strong and weak projections, respectively. Major brain divisions seen through the transparent cortex are represented by different background colors.
(C and D) Subcortical structures send inputs to bilateral, ipsilateral, or contralateral CLA (C), and the CLA sends outputs to some structures ipsilaterally or bilaterally (D).
