Isolated surgical lesions were made in three Macaca mulatta monkeys. Two had right optic tract section. One control underwent section of the right half of the chiasm. Preoperative evaluation revealed no fundus, pupil, or VER abnormalities. Postoperatively, a classic Marcus Gunn pupil was found contralateral to the isolated optic tract lesions. The control had normal pupils. The nature of the le...

It seems to be an open question whether Propositional Dynamic Logic (PDL) has Craig Interpolation. In fact, it even seems to be an open question if this is an open question: Multiple proofs have been claimed to be found but all of them also have been claimed to be wrong, both more or less publicly.

THE Marcus Gunn phenomenon is a well-known clinical entity wherein abnormal palpebral movements are associated with movements of the jaw. No record has been found in the literature of a case in which an associated concomitant convergent strabismus corrected itself automatically with the elevation of the ipsilateral ptotic lid when the jaw was opened or when ptosis was passively or surgically co...
