title: [Activities evoked in different strain structures by stimulation of the contralateral tectum in the chick].
abstract: In the chick, as soon as hatching, the responses recorded in various areas in the "accessorius hyperstriatum" (Wulst) seem to be very localized in relation with the stimulated region of the contralateral tectum. Very similar results are obtained within the other striate structures. These observations suggest in first part, that the tectal efferents project very diffusely to various striate structures and, in other part, that it exists in these a rather precise tectotopy and a columnar organisation. These results appear very constant during the first month of the hatching.
