The claims behind it

clm-1s2876z90hpresentanterograde tracerstrength: weakproposed

A weakly labeled site posterior to the S2 spot appeared in all genital cortex injections. The authors tentatively assign it to area PV, a further somatosensory field.

Made by an AI model reading the paper (claude-opus-5-5, extract@0.3.0); a second AI model (claude-opus-5-5) disagrees. “The object ID is the one used for secondary somatosensory cortex, but the paper treats PV as a separate area posterior to S2.”

A strongly labeled spot in putative S2, at the S2 genital location, appeared in every penis and clitoris cortex injection. Weaker label was seen at contralateral S2.
