Common neural mechanisms for the evaluation of facial trustworthiness and emotional expressions as revealed by behavioral adaptation.

abstract：:Surfaces possessing steep variations in depth present severe difficulties for orientationally tuned filter models of stereopsis. These difficulties are discussed in connection with a random-dot stereogram depicting a surface with steep horizontal corrugations. As expected on theoretical grounds, we find that a vertica...
